The specialist lender has increased its overall lending threshold from £2.5 million to £5 million and removed the cap on the number of portfolio properties it will lend on.

It is also increasing the maximum loan for individual properties from £2 million to £3 million and accepting refinance applications within six months of the initial purchase.

In addition, The Mortgage Lender will now accept buy-to-let applications for properties on Anglesey and the Isle of Wight and lend on HMOs that are leasehold flats.

The Mortgage Lender sales director Steve Griffiths said: “The criteria enhancements reflect what our broker partners have told us is important for them and their clients.

“It is only by having close relationships and being involved in the conversations about borrowers and properties that fall outside normal lending criteria that we are able to respond in this way and change how we operate to better meet the needs of brokers and their clients.

“We will continue to listen to our broker partners and make changes to our criteria and products to help more investors finance their BTL portfolios.”
