Should I expand my buy-to-let portfolio during 2025?

The rental market has changed in recent years. While once a sure-fire way to secure relatively passive income, owning a buy-to-let has become a legal minefield, with rental regulation impacting millions of residential landlords and investors, and officially shifting more power to the tenant. With this in mind, deciding whether to expand your buy-to-let portfolio or wind it up has been the question on every landlord’s lips during 2025.

In this blog post, we weigh up the pros and cons, so you can decide the next best step for you and your buy-to-let investments…

Expand now to take advantage of great market conditions

It has never been a better time to purchase a property in the UK. Falling mortgage rates are making it more economical than ever, while there is a whole world of better financing options available to those looking to remortgage or buy property. It’s not just home movers and first time buyers that are feeling the positives either.

Landlords like you can benefit from current mortgage rates and deals. With property prices also stabilising and less competition from homeowners, you could even bag yourself a bargain, especially if you’re buying regionally outside of the capital! The ever-shrinking pool of landlords also means there is a gap in the market for those looking to take advantage of record-high tenant demand and rental prices.

It’s a worrying time for landlords looking to invest in the UK

Great conditions are one thing, but there are several reasons why landlords are exiting the market left, right and centre. We’ll let SpareRoom share the latest statistics:

“A record number of landlords (88%) have no confidence in the current private rental sector, a figure that increases to 90% in London. More than a third (34%) of landlords plan to leave the sector altogether this year, spelling a stark reduction in long-term rental supply – meaning higher costs for tenants. Almost one in three (29%) landlords plan on reducing the size of their portfolios this year, while 4% prepare to switch their property to a ‘short-term holiday rental’.”

Changes to legislation – in particular the long-awaited Renters (Reform) Bill and abolition of Section 21 – and the high tax burden are also making more and more landlords explore alternative options, including those with far less hassle and risk.
