Digital mortgage broker, Tembo, has launched its new buy-to-let mortgage journey.

Its online tool aggregates data from over 50 buy-to-let lenders to calculate a landlord’s true affordability. The tool also generates a personalised buy-to-let plan which includes live interest rates and details of monthly repayments.

Tembo’s online planning tools also show users specialist options including top-slicing (where landlords use their own income in combination with rental income) to boost their borrowing power. It claims it is the only online platform where buy-to-let landlords can combine multiple income sources to calculate affordability.

Users can specify their preferences, for example, whether they want a fixed or tracker rate deal, how long they want to fix for, the mortgage term (up to 40 years) and the repayment type (capital repayment, or interest-only).

Eddie Ross, co-founder and chief product officer at Tembo, said: “We’ve seen the market become increasingly restrictive for buy-to-let affordability in the past year, a change that’s forced many landlords to consider selling up. We know it’s not easy to build a true understanding of one’s affordability through a digital experience.

“By combining the rental yield with all of an individual’s other income sources (pension, employment, benefits etc), we build a more nuanced and accurate picture, so they can make an educated decision.”
