Most banks and building societies (and some other financial institutions) offer BTL mortgages, but terms, conditions and costs vary enormously.

Some mortgage providers will not lend to individuals who are under 25 years of age or earn less than £25,000 a year. Lenders may impose an ‘upper’ age limit on the term of the mortgage by insisting that the mortgage is repaid in full before the borrower reaches a certain age — 70 is not untypical.

Flats, newly built property, former local authority-owned properties — or properties which are priced below a certain value — can be unacceptable to lenders. Lenders may also restrict the number of BTL mortgages a borrower can have with them at any one time. Or the lender may impose a ‘cap’ on the total amount of BTL funding they are prepared to advance to a borrower.
