In short: Lenders will usually lend buy-to-let on a vacant property if it's in habitable condition and the expected rent passes their interest cover test, often 125% to 145% of the mortgage interest at a stress rate. The lender's valuer will estimate the rent; a letting agent's written rental valuation helps. If the property needs work, such as a new kitchen or bathroom, you may need bridging finance first and then refinance. Fraser Bond can provide a rental valuation and find a tenant.
