Barclays borrowers will only be able to hold a maximum of four buy-to-let mortgages from today.
Borrowers could previously have had their suitability for exceeding this limit assessed on a case-by-case basis but the lender says it has scrapped this possibility as part of a policy review.
A spokeswoman says: “Barclays is committed to the buy-to-let market and our product range is continuing to prove popular as we support this important sector of the market. We regularly review our mortgage lending policy and have made some minor changes to clarify our position in the buy-to-let market.”
Barclays says close to all of its buy-to-let business is for customers with two rental properties at most.
