NatWest Intermediary Solutions is making changes to its buy-to-let calculator by using actual rather than assumed letting agent costs.

By no longer assuming letting agent costs for higher rate tax payers, NatWest can collate a clearer picture of a customer’s expenditure and ensure they are not impacting those who are not paying letting agents fees.

The calculator will therefore have up to two more additional questions but it will still enable small landlords with three or less mortgaged properties, as well as portfolio landlords mortgaging with no additional borrowing, to quickly and easily understand how much they can borrow.

Mark Bullard, head of sales, said: “These changes further demonstrate our commitment to improving our buy-to-let proposition for brokers and customers and will ensure that as a responsible lender we guarantee that our lend amount reflects the customers true costs.”
