A majority of UK buy-to-let landlords are choosing to stay the course, with nearly 60% indicating they have no plans to sell any properties in the coming year. The latest figures from the BTL lender show that 58% of landlords intend to retain their entire portfolio—up from 47% in the previous year’s survey, conducted shortly after the Autumn Budget.

Although some landlords are considering partial sales, the appetite remains limited. Just 15% expect to offload up to 10% of their holdings, while only 4% are looking to sell as much as a quarter. Fewer than one in ten plan to divest up to half of their portfolio.

Among those preparing to sell, the most commonly cited motivation was increased regulation—particularly the proposed Renters’ Rights Bill—which influenced 35% of sellers. Tax pressures followed closely, with 31% pointing to landlord taxation as a key factor in their decision.

In the previous year’s poll, over half of landlords—51.4%—identified regulation as their primary concern.

The BTL lender’s latest research, carried out in May 2025, gathered responses from buy-to-let landlords managing a combined total of around 3,000 properties.

Importantly, the survey was conducted before reports surfaced suggesting the Treasury may introduce National Insurance charges on rental income—a proposal expected to feature in the upcoming Autumn Budget.

A spokesperson for the lender said: “This latest survey data is hugely encouraging and once again demonstrates just how robust and resilient buy-to-let landlords are.”

“In the face of increasing operating costs and the threat of new legislation, this commitment from landlords to stay put is a huge win for the PRS and for renters all over the country – especially when you consider the massive role rented accommodation plays in the UK’s housing mix.”

He added: “We know this isn’t the story for all landlords, and while selling is a natural part of a developing a successful portfolio, there are still those just looking to scale back. As a sector, we absolutely need to get behind these landlords and give them the confidence to not just stay put, but to expand and succeed.”
