Around 697 former rental properties are being listed for sale every single day, according to Savills data published by Mortgage Solutions on 1 May 2026. That is 254,000 homes in the 12 months to March 2026. The landlord exit wave is not slowing - it is accelerating.
The Numbers Behind the Exit Wave
The 254,000 figure is a 28% increase on 2024, and a 9% rise on the same period last year, according to Savills (Mortgage Solutions, 1 May 2026). In London, the shift is even sharper. Former rental properties now account for 30% of all new sale instructions in the capital. That compares to just 13% across the rest of Britain.
Lucian Cook, head of residential research at Savills, was direct about why: "For many landlords, the Renters' Rights Act has become a clear point at which to reassess their investment. This has been compounded by fixed rate mortgages coming to an end and wider regulatory pressures, including higher minimum energy-efficiency standards." (Mortgage Solutions, 1 May 2026)
That last point matters. A landlord on a five-year fix that started in 2021 is now refinancing into a completely different rate environment. If their original BTL rate was 2.1% and they are now facing 4.7% or higher, the monthly payment on a £200,000 interest-only mortgage jumps from roughly £350 to around £783. For a smaller portfolio, that arithmetic does not work. Selling becomes the rational call.
Cook also noted a rise in Section 21 notices being served, often as landlords test achievable rents before deciding whether to sell. More sales are expected in the coming months as this pipeline converts (Mortgage Solutions, 1 May 2026).
What This Means for Mortgage Costs and BTL Buyers
Here is where it gets interesting for investors on the buy side. When stock floods in from motivated sellers, prices on former rentals can soften. A property that was sitting tenanted at below-market rent may come to market at a modest discount to vacant possession value. That can help your loan-to-value (LTV) - the percentage of the property's value you are borrowing. Lower LTV means better rates. Better rates mean a lower monthly payment.
But do not get ahead of the numbers. Lenders still stress-test BTL mortgages at rates above the actual product rate, typically 1-2% higher, to make sure the rental income covers the mortgage payment at a stressed level. That is your ICR. Most lenders want rental income to cover 125-145% of the stressed monthly payment - higher for higher-rate taxpayers. If you are buying a former rental at a price that looks attractive, run the stress test first before getting attached to the deal.
Separate data from Investec found that 49.9% of all homes listed for sale in London in Q1 2025 had been rental properties at some point in the previous three years, up from 32.4% in Q1 2024 (Mortgage Solutions, 1 May 2026). And in Q2 and Q3, only one in 10 properties purchased were re-let. Rental supply is tightening. For landlords who stay in, that is a tailwind on yields.
Who Is Buying and What to Watch
Savills found that 14% of former rental homes listed for sale were purchased by other landlords, effectively recycling them back into the private rental sector (Mortgage Solutions, 1 May 2026). That is a meaningful number. Professional and well-capitalised investors are picking up stock from smaller, mortgaged landlords who cannot make the numbers work. Investec's Mandeep Dhillon put it plainly: "We are seeing well-capitalised landlords and property entrepreneurs acquire additional units as some part-time landlords exit the market." (Mortgage Solutions, 1 May 2026)
Cook flagged that refinancing events and tenant moves are likely to become the main sale triggers going forward. So the daily run-rate of 697 is unlikely to drop sharply any time soon.
If you are assessing a former rental as a potential acquisition, your checklist is straightforward. First, check the EPC (Energy Performance Certificate) rating - energy efficiency standards are tightening, and a poor EPC could mean capital expenditure on top of your purchase price. Second, run the numbers on BTL stress test affordability at current rates, not last year's. Third, look at comparable rents in the area. Falling rental supply should support your yield assumption, but confirm it with live data. You can pull local market context through the Property Filter software to sense-check asking rents against local comparables.
The exit wave creates a genuine opportunity for buyers who have their finance in order. But that phrase - "finance in order" - is doing a lot of work. Get your mortgage arrangement confirmed, your stress test cleared, and your negotiation strategy set before you move.
Key Takeaways
254,000 former rental homes were listed for sale in the 12 months to March 2026, equivalent to 697 per day - a 28% increase on 2024 (Savills via Mortgage Solutions, 1 May 2026).
Motivated sellers can mean softer pricing for BTL buyers, but lenders still require rental income to cover 125-145% of stressed mortgage payments before approving a loan.
Consider running a BTL stress test at current rates on any former rental before proceeding, and you may wish to review EPC ratings and local rental comps as part of your due diligence.
