Lenders assess buy-to-let on rental cover rather than your income. We compare landlord lenders across the market.

Buy-to-Let Mortgages

How lenders assess buy-to-let

Buy-to-let lending is based mainly on the rent, not your salary. Lenders apply an interest coverage ratio (ICR), commonly 125% for basic-rate taxpayers and 145% for higher-rate, stress-tested at a notional rate of around 5.5%. This calculator shows the maximum loan the rent supports and your gross yield.

Criteria vary widely between landlord lenders, and the right one depends on your tax position, portfolio and the property. As a whole-of-market broker we find the lender that fits.

Your property may be repossessed if you do not keep up repayments on your mortgage. Not all buy-to-let mortgages are regulated by the Financial Conduct Authority.

Review of Nick Spolton

VouchedFor

I was looking for a mortgage to buy my first home. He found me the best mortgage for my personal circumstances. He listened to what I needed, offered advice and suggested options. I felt confident with his suggestions as Tom is very knowledgeable. He communicated regularly with me, keeping me updated at all times. He was always there when I needed him. Yes. Nothing.

We were first time buyers, with minimal knowledge on mortgages and the best options for us. Nick explained the process thoroughly, found us the best deal and made the application process so easy. He kept us updated with every step. Yes absolutely!

Fixed term mortgage deal coming to an end. Seth listened to what I wanted and the advice he gave me was good. He looked at deals and advised I stayed with the same mortgage lender. Whilst, this resulted in him not getting the business, he advised what I needed to ask for and contacted myself after the appointment with my current lenders advisor to see if everything was sorted out ok. Yes Nothing, Seth was really good and I will certainly recommend him to friends.
