"Our new range, which is available up to 75% LTV, meets the increase in demand from expat landlords and gives buy-to-let brokers more choice for their customers."
The products are available to expats with a minimum income of £40,000 (£60,000 for self-employed) and on a capital and interest, part and part or interest-only basis.
Available for both purchase and remortgage, initial rates start at 3.95% for a two-year fixed rate and 4.35% for a five-year fix at 70% LTV.
Applicants must be able to pay the mortgage from a UK bank account and have an agent or family in the UK who can oversee the property.
The expat products are available to the whole of the market, have a £150 application fee, a 2% completion fee and a maximum loan of £750,000.
The Mortgage Lender's deputy chief executive, Peter Beaumont, said: “There has been a 30% rise in the demand for expat buy-to-let mortgages year-on-year and our new range, which is available up to 75% LTV, meets the increase in demand from expat landlords and gives buy-to-let brokers more choice for their customers.”
