London has long been written off by buy-to-let investors as simply too expensive — but with certain areas experiencing price corrections back to 2017 levels, is it finally worth a second look? We dug into the data to find out exactly what the cheapest houses in London look like right now, and whether they stack up against the incredible value still available in the North.
What Does the Cheapest House in London Actually Look Like?
When you filter out auction properties, shared ownership schemes, retirement homes, and new builds on Rightmove, you are left with roughly 43,000 listings across London. What comes up at the very bottom of the price ladder is genuinely surprising — and not always in a good way.
The absolute cheapest "properties" available are houseboats, starting at around £90,000 to £97,000. After that, a single parking space for £100,000, and a 13-square-metre garage — also at £100,000 — with no planning permission to convert it into anything useful. Let that sink in: one hundred thousand pounds for a garage you cannot even fit a standard car into.
Filtering specifically for houses, the cheapest freehold option we found was a concrete-construction three-bedroom property at £220,000 in a repossession sale, cash buyers only. Concrete construction is a significant issue here, as most mortgage lenders will decline to lend on non-standard construction, limiting your buyer pool considerably when it comes to reselling.
The standout find, however, was a one-bedroom freehold house in Plaistow, East London — in the West Ham and Beckton area — listed at £275,000. It has a garden, is in reasonable condition, and sits close to the airport, which opens up some interesting serviced accommodation possibilities for short-term lets to business travellers and airline crew.
Does the Numbers Stack Up for Buy-to-Let?
Let us be honest about the figures on that £275,000 one-bed in E16. As a straightforward buy-to-let, comparable one-bedroom houses nearby are achieving around £1,500 per month in rent, with some potentially pushing towards £2,000. Using a 25% deposit — which would be £68,750 — and a repayment mortgage of £200,000 at a 4% interest rate, your monthly mortgage payments would sit at approximately £697. That leaves a monthly cash flow of somewhere around £500 after mortgage costs, before accounting for management fees, maintenance, and void periods.
It is not a terrible return, but the yield is thin. This is exactly why understanding your tax position is so important before committing to a London purchase. We would strongly recommend speaking with a specialist property accountant — Provestor is an excellent choice for landlords and investors navigating the complexities of buy-to-let taxation, including Section 24 mortgage interest relief restrictions that continue to affect profitability across the capital.
If your strategy involves adding value — converting a one-bed flat into a two-bed, extending into a loft under permitted development, or buying a short-lease property and extending — then London can start to make more sense. There are also notable opportunities in negotiating creative vendor finance deals on the many empty properties across the city, where owners have left homes sitting vacant for years without generating any rental income.
The Northern Alternative: Extraordinary Value Still on the Market
Here is where the comparison becomes almost uncomfortable. Within 40 miles of Birmingham, and across South Yorkshire and the North West, there are pages upon pages of two and three-bedroom freehold houses available for between £65,000 and £100,000.
A three-bedroom house in Sheffield, for example, was listed at £98,500. Comparable rentals within a quarter of a mile were achieving around £1,000 per month as a standard let. Spend £20,000 on a refurbishment and recent sold prices in the area suggest the property could be worth £160,000 to £180,000 — meaning you have manufactured equity on top of a healthy rental yield. That is a compelling flip-and-refinance or buy-to-let proposition by any measure.
In St Helens, a beautifully presented two-bedroom house in ready-to-rent condition was available for just under £100,000, likely to achieve over £1,000 per month in rent. The deposit required? Around £25,000. The yield? Substantially stronger than anything London can currently offer at equivalent price points. And in some cases, you even get a garage included — quite unlike paying £100,000 for one on its own in East London.

Our Verdict: London or North?
London is not entirely without opportunity in 2026, particularly for investors with an angle — whether that is serviced accommodation near an airport, lease extension plays, or creative finance on long-vacant properties. The price corrections in areas like Chelsea, where values have not moved since 2017, are genuinely interesting for the right strategy.
But for straightforward buy-to-let yields and accessible entry points, the North and Midlands remain far superior hunting grounds. The prospect of buying a solid family home for £80,000 to £100,000 — complete with a garage — will one day seem as extraordinary as the property prices of previous generations do to us now. The window will not stay open indefinitely.
