Not every London purchase is a Knightsbridge apartment. A good part of the money that comes from the Gulf goes into flats under £400,000 in zones 3 to 5, bought for rent rather than for the family’s own use. The yields are the best in the city, the entry price is a fraction of the prime districts, and management from abroad is routine. Four mistakes, though, turn a cheap flat into an expensive one.
Areas
Cheaper London: where a flat under £400,000 still makes sense in 2026
Why outer London zones give higher yields on cheaper flats
A flat under £400,000 suits a Gulf investor who wants a first London asset and income from the first month, not a family wanting somewhere to stay. In 2026 the money goes to Wembley Park, Stratford, the Royal Docks, Acton and Ealing, Woolwich, Croydon and Walthamstow, at £500 to £950 a square foot and gross yields of 4.5% to 6%. The catch is the running cost: a tower with a pool and 24-hour concierge turns a 5.5% gross yield into 4% net.
Rents fall more slowly than prices as you move out from the centre. A one-bedroom flat in Mayfair costs five times what one in Wembley costs and rents for about twice as much, so the gross yield in Wembley is roughly double. Add the stamp duty saving (the surcharges are the same percentage, but on a smaller price) and the running costs (service charges outside the ported prime blocks are a third of the level), and the outer zones are where a buyer who wants income starts.
What outer London flats give up on capital growth and resale
What they give up is capital growth over the long run and the depth of the resale market, which in the outer zones is made of other investors rather than families.
Districts where London flats under £400,000 make sense in 2026
The districts where the money goes in 2026, and what it buys:
Flats under £400,000 by district, 2026
| Area | What the money buys | Price per sq ft (indicative) | Gross yield |
|---|---|---|---|
| Wembley Park | New-build one-bedroom near the stadium and the Metropolitan and Jubilee lines | £650 to £850 | 5% to 5.5% |
| Stratford and the Olympic Park | One-bedroom in the newer towers; Elizabeth line, Westfield, universities moving in | £700 to £900 | 4.5% to 5.5% |
| Royal Docks and Silvertown | One- and some two-bedroom new-build on the river; DLR and Elizabeth line | £650 to £800 | 5% to 5.5% |
| Acton and Ealing | One-bedroom flats and conversions on the Elizabeth line, 15 minutes to Bond Street | £750 to £950 | 4.5% to 5% |
| Woolwich | New-build on the river with the Elizabeth line | £600 to £750 | 5% to 5.5% |
| Croydon | One- and two-bedroom flats in a regenerating centre, 15 minutes to London Bridge | £500 to £650 | 5.5% to 6% |
| Walthamstow | Conversions and small new blocks on the Victoria line | £650 to £800 | 4.5% to 5% |

The common thread is a fast line into the centre. Tenants in these districts are working in the City, Canary Wharf or the West End, and they rent where the journey is short and the building is new enough to be easy to live in. The Elizabeth line, opened in 2022, has done more for Acton, Ealing, Woolwich and the Docks than any other single change.
Four mistakes that make a cheap London flat expensive
The four mistakes we see most often in this part of the market:
- Buying the tower with the highest service charge. A 24-hour concierge, a pool and a cinema room cost the owner £5 to £7 per square foot a year. On a 500 square foot flat renting for £1,900 a month that is two to three months’ rent, and it turns a 5.5% gross yield into a 4% net one. Prefer buildings with a part-time concierge and no pool unless the rent clearly pays for them.
- Buying where everyone else is buying. A scheme of 800 identical flats sold to investors will have forty of them for sale and sixty to let at any time, and every one is priced against the others. Prefer smaller blocks, or the better buildings in a large scheme, and a flat that differs from the rest: a corner, a terrace, a higher floor.
- Ignoring the lease. Flats built between 2005 and 2018 often carry ground rents that rise on a schedule, some of them doubling. Lenders refuse them and buyers walk away. Check the ground rent clause before anything else; our leasehold guide explains what to look for.
- Buying on the launch brochure. Off-plan launch prices for the outer zones have often been above the price the same flats later sold for as completed resales. Check completed resales in the scheme and nearby before paying a launch price.
Worked example: net yield on a £385,000 Wembley Park flat
A worked example, indicative for 2026: a 520 square foot one-bedroom flat in Wembley Park at £385,000, let at £1,950 a month. Gross yield 6.1%. Service charge £2,600, ground rent nil, management at 12% of rent £2,800, an allowance of one month a year for void and repairs £1,950, insurance within the service charge. Net income about £16,000, a net yield of about 4.1% before tax. Stamp duty for a Gulf buyer who owns a home at home: about £32,000 on top of the price. The return is modest and steady; the point of the purchase is that it is modest and steady, from a distance, in sterling.
Who should buy a London flat under £400,000, and who should not
For the investor who wants a first London asset, income from the first month and a budget that would buy nothing in the centre, the outer zones are the right answer, and a portfolio of three or four such flats across two districts is a sensible structure.
For a family that wants somewhere to stay in London, they are the wrong answer; the family will not use a flat in Croydon, and the money is better in a smaller flat nearer the park. For a buyer who wants the strongest long-term capital growth, prime London has the longer record. We say which of the three a client is before showing them a single flat.

Frequently Asked
Questions about London flats under £400,000
A one-bedroom flat in a conversion or an older block in Bayswater’s cheaper streets, Pimlico’s edges or Bermondsey; a two-bedroom only in zones 3 to 5 or in the eastern boroughs.
Usually, by a point or two gross, because rents fall more slowly than prices as you move out; our guide on London rental yields by area has the borough figures.
London for a child at university or a future base; Manchester for income. Our Manchester guide sets out the yield case and its risks.
Croydon at 5.5% to 6% gross, then Wembley Park, the Royal Docks and Silvertown, and Woolwich at 5% to 5.5%. Stratford runs 4.5% to 5.5%, and Acton, Ealing and Walthamstow 4.5% to 5%. The common thread is a fast line into the centre; the Elizabeth line, opened in 2022, has done most for Acton, Ealing, Woolwich and the Docks.
About 4.1% before tax, on our indicative 2026 example. A 520 square foot one-bedroom flat at £385,000 let at £1,950 a month gives a 6.1% gross yield. After a £2,600 service charge, management at 12% of rent (£2,800) and a one-month allowance for void and repairs (£1,950), net income is about £16,000.
About £32,000 on top of the price for a Gulf buyer who already owns a home at home, on the worked example. The surcharges are the same percentage as in prime London, but on a smaller price, which is part of why the outer zones suit an income buyer.
Because it is a large share of a modest rent. A 24-hour concierge, a pool and a cinema room cost the owner £5 to £7 per square foot a year; on a 500 square foot flat renting for £1,900 a month that is two to three months’ rent, and it turns a 5.5% gross yield into 4% net. Prefer a part-time concierge and no pool unless the rent clearly pays for them.
Only after checking completed resales. Off-plan launch prices for the outer zones have often been above the price the same flats later sold for as completed resales, so check completed sales in the scheme and nearby before paying a launch price. Our off-plan or completed guide covers the choice.
The ground rent clause, before anything else. Flats built between 2005 and 2018 often carry ground rents that rise on a schedule, some of them doubling; lenders refuse them and buyers walk away. Our leasehold guide explains what to look for.
It is the crowded place to buy. A scheme of 800 identical flats sold to investors will have forty for sale and sixty to let at any time, each priced against the others. Prefer smaller blocks, or the better buildings in a large scheme, and a flat that differs from the rest: a corner, a terrace, a higher floor.
