As of May 2026, the UK buy-to-let market has seen a significant shift with 254,000 former rental properties listed for sale over the past year. This increase of 28% from March 2024 and 9% from March 2025 indicates a continued change in landlord activity. The implications of this trend are particularly pronounced for landlords and first-time buyers.
Impact on Landlords
Increased Section 21 Notices
Landlords have been increasingly serving Section 21 notices, often as a way to test achievable rents in the open market. Savills’ research found that 14% of the buy-to-let properties listed for sale were purchased by other landlords, effectively returning to the private rented sector. For instance, a landlord with a £200,000 interest-only buy-to-let mortgage could see their monthly cost drop from £917 to £875 by purchasing one of these properties.
London Market Shift
The shift is most pronounced in London, where former rental properties accounted for 30% of new sales instructions, compared with 13% across the rest of Great Britain. For a landlord with a £300,000 interest-only mortgage in London, this could mean a potential monthly cost reduction from £1,375 to £1,312.
Implications for First-Time Buyers
Increased Property Availability
The surge in former rental properties coming to market could provide more options for first-time buyers. For example, a first-time buyer with a £250,000 repayment mortgage at 75% loan-to-value (LTV) could see their monthly payments reduce from £1,432 to £1,389 — a saving of £43 per month or £516 per year. In another scenario, a first-time buyer at 90% LTV on a £200,000 property would see their monthly payments drop from £1,151 to £1,120, saving £31 per month or £372 per year.
Market Context
Compared to six months ago, the number of former rental properties listed for sale has increased by 9%. This is in line with the current Bank of England base rate of 3.75%, which is higher than the rate of 3.5% six months ago. This increase in base rate could be contributing to the shift in the buy-to-let market. Moreover, compared to a year ago, the number of former rental properties listed for sale has surged by 28%, indicating a significant change in the market dynamics.
Implications for Remortgagers
Increased Property Choices
Remortgagers could also benefit from the increase in former rental properties listed for sale. For instance, a remortgager with a £200,000 repayment mortgage at 75% LTV could see their monthly payments reduce from £917 to £875 — a saving of £42 per month or £504 per year. This could potentially offer more affordable options for those looking to remortgage.
Market Context
Compared to a year ago, remortgagers are now faced with a larger pool of properties to choose from, potentially leading to more competitive prices. This, coupled with the current Bank of England base rate of 3.75%, could influence their decision to remortgage.
