Where to Buy Property Investments in Hounslow: Yields up to 5.7%

Investing in Hounslow? See buy-to-let deals across the UK→

Hounslow is a borough of west London. The average sold price across Hounslow is £509,325 on the HM Land Registry House Price Index, 75.7% above the England average of £289,946 but below the £542,065 London regional average, which makes it one of the more affordable boroughs in West London. The unusual part sits underneath that headline. A Hounslow terraced house sells for 143.4% more than the England terraced average, a steeper premium than the borough's detached stock carries at 116.1%, because in this part of London it is the ordinary mid-market home, not the rare detached one, that the market bids up. That is the stock most buy-to-let investors actually buy. UB2 (Norwood Green) returns the highest gross yield in the borough at 5.7% on a £414,353 asking price, near the bottom of the Hounslow range. The local authority's population grew 13.48% between the 2011 and 2021 censuses, from 253,957 to 288,181 residents.

Twelve postcodes cover the borough, and several reach well beyond it. TW1 sits in Twickenham across the river in Richmond, TW15 and TW19 stretch into Ashford and Stanwell on the Surrey edge, UB2 takes in Southall's Norwood Green, and W4 is Chiswick, so the PropertyData figures for those postcodes reflect the whole postcode district rather than the Hounslow slice. The data tables below cover all twelve, from the £379,681 entry in TW13 (Feltham, Hanworth) to the £744,235 asking price in W4 (Chiswick, Gunnersbury), a 96.0% spread inside a single borough.

This guide covers the London Borough of Hounslow (ONS code E09000018) in the south-west of the capital, running from Chiswick in the east out to Feltham and the Heathrow fringe in the west. Neighbouring areas include Richmond to the south, Ealing to the north, Hillingdon to the west and Spelthorne across the Surrey border. For investors weighing up where to buy across the UK, Hounslow sits at the point where Heathrow's job base, the Great West Road employers and a long transport spine all meet. The wider Ealing and Brent markets to the north share much of the same West London tenant pool.

Why Invest in Hounslow?

Hounslow added 34,224 residents between the 2011 and 2021 censuses, a 13.48% rise to 288,181 that runs more than double the 6.3% England and Wales average. Few outer London boroughs grew that fast. The borough sits in a wedge of West London bracketed by the Thames at Chiswick and Brentford and the runways at Heathrow, and it has absorbed new residents into Feltham, Hounslow town and the Brentford riverside without the price volatility of the inner boroughs. That steady inflow of people is the bedrock of rental demand here.

The local economy is wired into the airport. Transportation and storage is the single largest employment sector at 22.8% of employee jobs, far ahead of any inner-London borough, reflecting Heathrow's logistics, cargo and airline base on the borough's western edge. Wholesale and retail follows at 13.6%, information and communication at 13.0%, with the Great West Road's media and corporate offices feeding that figure, then administrative and support services at 9.3% and accommodation and food at 6.8%. It is a working economy of shift patterns and hospitality as much as office jobs, which spreads tenant demand across price points and supports both standard lets and the short-let market near the airport.

Median gross annual earnings for Hounslow residents are £40,870, which is 4.5% above the Great Britain median of £39,125 but 11.9% below the London regional median of £46,415. That gap matters for a landlord. Hounslow tenants earn London-fringe wages rather than central-London salaries, so affordability bites earlier here than it does closer in, and the postcodes where rent takes the smallest share of income are the ones with the steadiest demand.

Regeneration and Investment in Hounslow

Hounslow has launched a £7.5 billion regeneration of its Great West Road corridor, with 14,000 homes and 25,000 jobs planned across the four-kilometre stretch from Chiswick to Syon Lane. The investment is concentrated along the riverside and the old industrial Golden Mile, where two of the borough's largest schemes are already on site.

• The Brentford Project (Under construction, approximately 900 homes): Ballymore is building nearly 900 new homes alongside retail, leisure and workspace on the south side of Brentford High Street, knitting the town centre back to its waterfront where the Grand Union Canal meets the Thames. The scheme sits beside the Gtech Community Stadium, and its scale adds a substantial residential population to a town centre that had stagnated for decades. Updates at Ballymore.
• Golden Mile London (Masterplanning, 14,000 homes, £7.5 billion): Hounslow Council approved £1 million of first-phase funding in 2025 to bring forward this 15-year programme along the Great West Road, targeting 14,000 homes and 25,000 jobs on the corporate corridor between Chiswick and Brentford. The plan turns a stretch known for office blocks and the GSK and Sky campuses into a mixed residential and employment district served by the Piccadilly line and the area's mainline rail links. Updates at Hounslow Council.
• Future Feltham (Masterplanning, up to 3,000 homes): The Future Feltham Investment Framework, approved by Hounslow Cabinet in December 2025, sets a 15-year plan to deliver up to 3,000 homes around Feltham town centre and the former Ministry of Defence site, which the Mayor of London designated a Housing Zone. Feltham is the cheapest entry point in the borough at a TW13 asking price of £379,681, so a sustained council-led pipeline here lands in the postcode with the most room to move. Updates at Hounslow Council.

Hounslow Property Market Analysis

Average property prices in Hounslow have risen 520.8% since January 1995, from £82,041 to £509,325. The sections below break down that journey cycle by cycle, then drill into current postcode-level data for sold prices, price per square foot, asking prices, growth trends, and monthly transaction volumes.

When was the last house price crash in Hounslow?

Hounslow's sold prices are recorded by HM Land Registry at London borough level, ONS code E09000018, so the figures here cover the whole borough. The Land Registry House Price Index tracks average prices from January 1995 to March 2026, covering 31 years of market cycles.

The 1995 to 2007 boom: Hounslow started at £82,041 in January 1995. By December 2000, prices had reached £156,483, a 90.7% increase in six years as London's market ran hard through the dot-com years. Growth continued through the early 2000s, reaching £252,793 by December 2005. The market peaked at £311,550 in October 2007.

2008 to 2009, the financial crisis: Prices fell from the October 2007 peak of £311,550 to a trough of £255,391 in April 2009. That is a decline of 18.0% over 18 months. The worst year-on-year reading was -17.7% in May 2009. Hounslow's fall tracked the wider market closely, sitting between the England decline of 18.2% (from £183,883 in September 2007 to £150,438 in March 2009) and the London regional fall of 17.8% (from £319,663 in January 2008 to £262,661 in April 2009). A borough this tied to one airport and one trunk road felt the credit crunch as sharply as anywhere in outer London.

Recovery, 2010 to 2012: London led the national recovery, and Hounslow came back faster than most of England. Prices climbed off the April 2009 trough to £289,937 by December 2010, and by September 2012 the average reached £314,097, finally surpassing the October 2007 pre-crash peak of £311,550. That took just under three and a half years from the bottom, well ahead of the eight-and-a-half years many northern markets needed.

The 2013 to 2016 surge: This was Hounslow's strongest run. Prices jumped from £342,647 in December 2013 to £388,184 by December 2014 (13.3% annual growth) and £435,062 by April 2016, as London's post-crisis boom and a wave of buy-to-let buying ahead of the April 2016 stamp duty surcharge pulled prices up fast.

2017 to 2019, the plateau: Growth flattened as London's prime ripple ran out of momentum. Prices edged from £458,920 in December 2017 to £467,876 by December 2019, with annual growth dropping into low single digits. The borough was catching its breath after the surge.

2020 to 2022, the pandemic rebound: After a brief dip to £451,496 in June 2020, the stamp duty holiday and a shift towards more space lifted prices to £486,715 by December 2020 and on to a then-high of £536,611 by November 2022 (12.3% annual growth in the year to that month). Outer London with gardens and fast trains suited the moment.

The 2023 rate shock: Higher mortgage rates cooled the market. Prices eased to £498,443 by December 2023, recording -6.7% annual growth, a sharper correction than many cheaper regions saw because London's higher prices carry more mortgage debt per pound.

2024 to present: The market recovered to £525,299 by December 2024 (5.4% annual growth) and reached an all-time high of £538,581 in August 2025, before easing back to £509,325 by the latest reading in March 2026. That recent softening of 5.4% off the August peak is the part a single annual figure hides. The current price is 63.5% above the pre-crash peak of £311,550.

Long-term growth summary:

• 5 years (March 2021 to March 2026): 6.5% growth (£478,350 to £509,325)
• 10 years (March 2016 to March 2026): 17.3% growth (£434,141 to £509,325)
• 15 years (March 2011 to March 2026): 69.4% growth (£300,582 to £509,325)
• 20 years (March 2006 to March 2026): 93.8% growth (£262,812 to £509,325)
• 30 years (January 1995 to March 2026): 520.8% growth (£82,041 to £509,325)

The 30-year return of 520.8% is among the strongest of any English location, driven by London's long bull run from a low 1995 base. The shape of the last five years is the more useful read for a buyer today: just 6.5% growth over the period, an all-time high in August 2025, and a 5.4% easing since. Hounslow recovered from 2009 in under three and a half years, far quicker than most of England, but an investor who bought at the August 2025 high is currently holding a small paper loss. The borough has done its heavy lifting on capital growth already, and the recent numbers point to a market that has plateaued near its ceiling.

Sold House Prices in Hounslow

The average sold price across all property types in Hounslow is £509,325, which is 75.7% above the England average of £289,946 as of March 2026. A London premium runs through every property type, but it is heaviest where you might least expect it. Terraced houses carry the steepest premium at 143.4% above England, ahead of the borough's detached premium of 116.1%. In most of the country the rarest, largest homes command the biggest premium; in Hounslow the everyday terraced and semi-detached stock does, because that is the bulk of what changes hands in a borough with relatively few detached houses.

Detached houses at £1,016,518 are the one type to clear seven figures, 116.1% above the England detached average. They are scarce here, concentrated in the Surrey-fringe postcodes like TW19 (Stanwell, Wraysbury) and the larger plots of TW15 (Ashford), and they sit outside the range of most buy-to-let buyers. This is owner-occupier territory.

Semi-detached houses at £689,810 carry a 139.4% premium over England's £288,185, the second-steepest in the borough. The semi is Hounslow's family workhorse, found across Heston, Cranford and the Feltham streets, and it is the type that pulls the borough's overall average up so far above England. For a landlord chasing a multi-occupancy or family let, this is the core stock, priced firmly.

Terraced houses at £593,275 show the borough's biggest premium at 143.4% over England's £243,788. The terraced stock is heaviest in TW1 (Twickenham) and the older streets of Hounslow and Isleworth, and London prices it as a genuine alternative to a flat for a family. That 143.4% gap is the clearest sign that in this borough the mid-market home, not the detached one, is where the London premium concentrates.

Flats and maisonettes at £342,569 carry the smallest premium at 59.7% above England's £214,563. Brentford's riverside blocks, the Chiswick conversions in W4 and the new-build flats along the Great West Road make up most of this stock. A flat is the lowest-cost way into the borough and, as the rental tables below show, often the highest-yielding.

Price Per Square Foot in Hounslow

£383 per square foot separates Hounslow's cheapest postcode from its dearest, with TW19 (Stanwell, Wraysbury) at £466 and W4 (Chiswick, Gunnersbury) at £849. Measuring by the square foot strips out how big the homes are and isolates what each location itself commands. The TW and UB postcodes on the western, Heathrow-facing side of the borough cluster tightly in the high £400s to low £500s, then the eastern, riverside postcodes step up sharply.

TW19 at £466 is the cheapest space in the borough, on the far western edge where Stanwell and Wraysbury sit between the reservoirs and the Heathrow perimeter. That is reflected in the price: the same money buys more floor area here than anywhere else in Hounslow, drawn from 212 transactions analysed.

W4 at £849 is the dearest, 82% above TW19. Chiswick is a different market from the rest of the borough, with period terraces, riverside conversions and a high street that competes with inner-London neighbourhoods. Across 637 transactions analysed, W4's per-square-foot rate sits closer to Hammersmith than to Feltham, which is why an investor's pound stretches so much further three miles west.

For Sale Asking Prices in Hounslow

TW13 at £379,681 and W4 at £744,235 sit 96.0% apart, nearly a doubling in price across a single borough's twelve postcodes. That hierarchy mirrors the per-square-foot table: the western Feltham and Heathrow postcodes anchor the bottom, and the eastern riverside postcodes top it out. The mean asking price across all twelve Hounslow postcodes is £512,043.

TW13 at £379,681 is the cheapest way into the borough, in Feltham and Hanworth on the western side. It is the only postcode under £400,000 and the focus of the council's Future Feltham housing pipeline, so the entry point with the most regeneration money behind it is also the lowest. For an investor working to a fixed budget, the lower asking prices and the buy-to-let stock sit in this western band rather than the eastern riverside. Below market value purchases through below market value properties can lower that entry cost further.

W4 and TW1 sit in a tier of their own above £739,000, almost double the Feltham entry. Chiswick (W4) and Twickenham (TW1) are riverside, period-stock postcodes whose buyers compete with inner West London, and both reach beyond Hounslow into Richmond. They are owner-occupier markets where the rental yield, as the sections below confirm, runs at the bottom of the borough.

House Price Growth in Hounslow

TW4 (Hounslow West) leads on five-year growth at 21.0%, while the two riverside postcodes W4 and TW8 are both down over three years, W4 by 8.3%. Every postcode but one posted positive five-year returns, but the recent year splits the borough. The western Feltham and Hounslow postcodes are still rising, while the premium riverside end has stalled or slipped.

TW4 at 21.0% over five years has been the borough's strongest performer, with 7.4% added in the last year alone. Hounslow West has caught the affordability shift, as buyers priced out of the eastern postcodes moved west along the Piccadilly line into cheaper stock, and the growth has followed. UB2 tells a related story: its 17.1% three-year growth is the highest in the borough, though that has cooled to 7.6% over five years, a Southall-edge postcode that ran hard then settled.

W4 and TW8 sit at the other end of the recent record. Chiswick (W4) is down 8.3% over three years despite a 5.1% five-year figure, and Brentford (TW8) is down 6.6% over three and 4.5% in the last year, the weakest twelve-month reading in the borough. Both are flat-heavy riverside markets where the wave of new-build apartments has weighed on prices, and TW3 (Hounslow) is the only postcode with a negative five-year return at -2.2%.

Monthly Property Sales in Hounslow

Transaction volumes run from 8 sales a month in TW4 to 25 in W4, with the wider borough turning over a steady flow of stock across all twelve postcodes. Turnover rates, the share of for-sale stock that changes hands each month, tell a sharper story. They run from 3% in TW8 up to 12% in TW14, and that spread maps onto how quickly each postcode actually moves.

TW14 (Hatton, North Feltham) has the highest turnover at 12%, well clear of the rest, so its smaller, cheaper stock changes hands fastest. For a buy-to-let investor, higher turnover means an easier exit when the time comes to sell, because there are always comparable sales and active buyers in the market.

W4 records the most sales at 25 a month but on a 5% turnover rate, because Chiswick has a far larger pool of for-sale stock, so a healthy number of sales still represents a small share of it. TW8 (Brentford) sits at the bottom on 3% turnover, the lowest in the borough, where the volume of riverside new-build flats has built up a deep standing supply that takes longer to clear.

How Long Properties Take to Sell in Hounslow

Selling speed splits Hounslow wide open: TW14 (Hatton, North Feltham) finds a buyer in around 277 days, while TW8 (Brentford) sits on the market for roughly 1,014 days. Days on market is how long a typical home is listed before it sells; the months of unsold stock shows how much for-sale supply is queued up at the current rate of sales. The two readings together separate the postcodes that move from the ones that linger.

How long your money is tied up at the end of a hold rarely makes it into the yield maths, and Hounslow is a borough where it should. TW14 clears in about 277 days against TW8's 1,014, so a sale in Brentford can take the best part of three years longer to complete than one in North Feltham. That gap is a real holding cost on exit, and it is heaviest in the flat-dominated riverside postcodes, TW8 with 33.3 months of unsold stock chief among them, where standing supply is deep and buyers can take their time.

What Type of Property Can You Buy in Hounslow?

Flats are the single largest property type in seven of Hounslow's twelve postcodes, peaking at 63.2% of stock in TW8 (Brentford), while detached houses are scarce across the borough. The mix of housing stock shapes which strategy fits each postcode. The figures below are drawn from 2021 Census records for each postcode.

TW8 (Brentford) is the most flat-dominated postcode at 63.2%, followed by W4 (Chiswick) at 53.7%, the two riverside postcodes where new-build apartment schemes and Victorian conversions concentrate. That flat-heavy stock lines up with their slower selling times and softer recent growth, but it is also the lowest-cost entry into those postcodes for a single-let or short-let strategy near the river and the stadium.

TW19 (Stanwell, Wraysbury) is the outlier at the other end, with 33.6% detached houses, by far the highest in the borough, and just 14.5% flats. This is the rural Surrey fringe between the reservoirs, owner-occupier family stock rather than the smaller units that drive rental income. The semi-detached share peaks in TW15 (Ashford) at 45.9% and TW5 (Heston, Cranford) at 42.9%, the family-home heartland of the borough.

The flats figure covers both purpose-built blocks and converted units. A small share of non-standard dwellings is excluded, so rows may not total 100%.

Hounslow Rental Market Analysis

Monthly rents in Hounslow run from £1,657 in TW14 to £2,596 in W4, with gross rental yields from 3.3% to 5.7% across all twelve postcodes. For investors weighing up whether buy to let is worth it in Hounslow, the sections below break down rents, yields and tenant affordability postcode by postcode. If you are working out how to build a property portfolio in West London, Hounslow's Heathrow-anchored job base and fast inflow of residents give it a deeper tenant pool than its headline yields suggest.

Average Rent & Gross Rental Yields in Hounslow

Gross rental yields in Hounslow range from 3.3% in TW1 to 5.7% in UB2. The pattern is the familiar London one: the cheaper western postcodes deliver the better yields, and the premium riverside postcodes deliver the lower ones. UB2 (Norwood Green) tops the table at 5.7% on a £1,963 rent and a £414,353 asking price, while TW1 (Twickenham) sits last at 3.3% because its £739,427 asking price swamps a £2,008 rent.

UB2 at 5.7% pairs the third-lowest asking price in the borough with a strong £1,963 rent, drawn from the dense, mixed Southall-edge market at Norwood Green where rental demand runs deep. A 30% deposit of £124,306 buys into the highest-yielding postcode in Hounslow.

TW8 (Brentford) is the interesting one. Its 5.3% yield is third-highest in the borough, sitting on the highest rent outside Chiswick at £2,205, as the new riverside flats let well to professionals working the Great West Road and Heathrow. The catch is the exit: TW8 is the slowest postcode to sell and the softest on recent growth, so the strong income comes with a long road out.

TW1 (Twickenham) at 3.3% sits at the bottom. The £2,008 rent is healthy, but a £739,427 asking price compresses the income return. As with W4, the premium riverside postcodes are bought for the location and the capital, not the yield.

Is Hounslow Rent High?

Monthly rents in Hounslow take between 48.7% and 76.2% of the local median gross salary, well above the 30% affordability threshold in every postcode. The widely cited line for rent affordability is 30% of gross income. No Hounslow postcode comes close to it, which is the clearest measure of how stretched a single local earner is here. London rents set against London-fringe wages leave little headroom.

The median gross weekly salary for Hounslow residents is £786.00, which equates to £3,406 per month or £40,870 per year. This is above the Great Britain median of £752.40 per week but below the London regional median of £892.60 per week. Data from the Nomis Labour Market Profile (ASHE 2025).

TW14 (Hatton, North Feltham) at 48.7% is the most affordable postcode for a single local earner, and TW15 (Ashford) at 49.2% is close behind, the only two under half of gross income. These western Feltham postcodes are where a tenant on the local median wage has the most headroom, which tends to mean fewer arrears and longer tenancies for a landlord.

W4 (Chiswick) at 76.2% is the least affordable by a wide margin, but the figure overstates the strain because the median Hounslow salary is the wrong yardstick for Chiswick. Tenants paying £2,596 a month in W4 are typically dual-income professional households or earners well above the borough median, drawn by the riverside setting and the District line rather than priced against local wages.

How Big Is Hounslow's Private Rented Sector?

The private rented sector is deepest in TW3 (Hounslow) and TW4 (Hounslow West), where it houses 39.2% and 38.3% of households, and shallowest in the Surrey-fringe postcodes TW15 and TW19 at 16.6%. The share of homes already rented privately is a guide to the size of the established tenant pool. The table below shows household tenure by postcode.

TW3 and TW4 around Hounslow town and Hounslow West have the deepest private rented sectors in the borough, close to four in ten households, a proven and active lettings market built around the town centre and the Heathrow workforce. A large existing rented sector points to ready tenant demand and a wide pool of comparable lets, which is part of why those postcodes let so fast. TW3 and TW4 also pair that depth with solid yields of 4.9% and 5.0%.

The Surrey-fringe postcodes TW15 (Ashford) and TW19 (Stanwell) sit at the other end, with private renting at 16.6% and owner-occupation above 65%. These are settled family-ownership areas where the rental market is thinner, which fits their lower yields and their detached, larger-home stock. Brentford (TW8) is the standout for social renting at 31.6%, the legacy of its estate stock alongside the new riverside flats.

Rental demand across most of the borough is strong. Homes in TW3 let in around 13 days on average and TW4 and TW5 in roughly 15 to 16 days, with most postcodes reading as a landlord's market on PropertyData's rental measure, meaning tenants outnumber available homes. UB2 is the one balanced exception, where homes take longer to let at around 82 days.

Local Housing Allowance Rates in Hounslow

Hounslow spans four Broad Rental Market Areas, so Local Housing Allowance varies across the borough, from a £278.93 weekly two-bedroom rate in the Walton area up to £373.97 in Inner West London. Local Housing Allowance sets the maximum housing support a tenant on benefits can receive, so for that part of the market it acts as a rent floor. Unlike most boroughs, Hounslow's postcodes do not share one rate, so the table below sets out the rates by area as of June 2026. To check the current rate for a specific address, you can use the government's official Local Housing Allowance calculator.

Most of Hounslow falls within the Outer West London market area, where the two-bedroom LHA rate of £299.18 a week works out at about £1,296 a month, comfortably below the £1,657 to £2,205 open-market rents recorded across those postcodes. The benefit-funded segment therefore sits under Hounslow's market rents, and the stock that fits within these rates is concentrated in the cheaper Feltham and Hounslow postcodes. The eastern riverside postcodes TW8 and W4 fall into the higher Inner West London area at £373.97 for a two-bed, while the Surrey-fringe TW15 and TW19 sit in the lower Walton area, so a landlord pricing a benefit-backed let needs to check which of the borough's four areas the property falls in.

Buy-to-Let Considerations

Are House Prices High in Hounslow? Price-to-Earnings Ratios

Purchasing a property in Hounslow requires between 9.3 and 18.2 times the median annual salary. This is based on the Nomis Labour Market Profile for Hounslow showing the median gross annual income for Hounslow residents is £40,870.

The national benchmark for price-to-earnings is 7.4x (England's average sold price of £289,946 divided by the Great Britain median annual salary of £39,125). Every Hounslow postcode sits above that national benchmark, which is what a London borough where the cheapest entry still costs over nine times local earnings looks like.

TW13 at 9.3x is the most affordable entry in the borough relative to local earnings, in Feltham and Hanworth. At a touch over nine times the local median salary it is still well above the 7.4x national benchmark, a reminder that even Hounslow's cheapest postcode carries a London price tag against a London-fringe wage.

W4 (Chiswick) at 18.2x and TW1 (Twickenham) at 18.1x sit nearly double the borough's affordable end. At more than eighteen times the local median salary these are firmly prime markets, bought by households earning well above the Hounslow median or trading equity in from elsewhere. The elevated ratio is the flip side of their low rental yields.

A 30% deposit on a buy-to-let property in Hounslow ranges from £113,904 in TW13 to £223,270 in W4. The gap between the cheapest and most expensive deposit is £109,366, very nearly the full cost of a second TW13 deposit. For investors comparing Hounslow with other West London boroughs, these deposits sit below Brent and Harrow but above Slough across the Berkshire border.

Beyond the deposit, the stamp duty calculation and other buy to let costs affect the total capital required.

TW13 is the cheapest way into the borough at a £113,904 deposit, in Feltham, and that buys into the postcode with the council's biggest regeneration pipeline behind it and a 5.6% yield, second-highest in the borough. Stepping up to UB2 costs about £10,000 more in deposit and buys the borough's top yield at 5.7%, so the two cheapest-to-enter yielding postcodes sit within a deposit step of each other.

At the top, W4 and TW1 each demand a deposit above £220,000, almost double TW13. That capital buys riverside Chiswick or Twickenham rather than more rental income, since both sit at the bottom of the yield table. The deposit gap across the borough is wide enough that the choice of postcode is really a choice between income at the western end and prime location at the eastern.

What the Hounslow Data Tells Buy-to-Let Investors

In Hounslow the yield is concentrated at the cheaper, western end of the borough. UB2 (Norwood Green) tops the table at 5.7%, with TW13 (Feltham) at 5.6% and TW4 (Hounslow West) at 5.0% close behind, and all three carry the lowest asking prices for buying an investment property in the borough. A 30% deposit in TW13 is £113,904, the lowest in Hounslow, against a rent of £1,759 a month.

Growth has been running in the same western postcodes. TW4 has grown 21.0% over five years and TW13 17.6%, while UB2 led the borough on three-year growth at 17.1%. The eastern riverside postcodes have moved the other way: W4 (Chiswick) is down 8.3% over three years and TW8 (Brentford) down 6.6%, both weighed down by a deep supply of new-build flats. So in Hounslow income and recent growth point at the same part of the map, the affordable Feltham-to-Hounslow-West band, rather than pulling in opposite directions.

The flip side is liquidity. The same western postcodes that yield and grow also sell faster, with TW14 clearing in about 277 days, while TW8 sits for around 1,014 days and 33.3 months of unsold stock. A higher income in Brentford comes attached to a slow and uncertain exit. Buyers who want to come in below asking often look through off-market properties channels, which matters more in the slower riverside postcodes where standing supply is deep.

Hounslow has no selective licence covering the whole borough, but it runs an additional HMO licensing scheme borough-wide, so landlords should check the current position for a specific property on Hounslow Council's HMO licensing pages. With a Heathrow-anchored job base, fast population growth and a deep private rented sector in the Hounslow town postcodes, the borough reads as a steady-demand, modest-yield London market: lower headline returns than the cheaper regions, on a tenant base that is wide and proven.

How Hounslow Compares

Hounslow's mean asking price of £512,043 is the second-lowest of five West London locations compared here, yet its top yield of 5.7% leads the group alongside Ealing. The comparison below places Hounslow alongside four nearby locations, each with a different investor profile. The mean asking price and mean monthly rent are simple averages across all postcodes with data. Top gross yield is the single highest postcode yield in each location.

Hounslow is the second-cheapest entry in this group at a £512,043 mean asking price, behind only Slough, and its 5.7% top yield is the joint-highest, level with Ealing and ahead of Brent and Harrow. The picture is a borough that combines a below-average West London asking price with a top-end yield, with the caveat that its mean rent of £1,920 is the second-lowest of the five.

Slough is the only cheaper entry in the group at £444,990, just over the Berkshire border, with a 4.8% top yield that trails the London boroughs. Ealing matches Hounslow's 5.7% top yield but at a higher entry and rent, while Brent at 5.6% and Harrow at 5.4% sit at the pricier end of the group.
