Please ensure you apply the correct interest rate for calculation purposes as most Lenders charge a 'higher' rate than the current pay rate on BTL schemes. See Product information section.
Most Lenders will only lend 85% of the purchase price/property value on BTL Mortgages (although one Lender will currently lend 89%) subject to the rental income proving sufficient.
Make sure you check the Lenders calculation rate. Details can be found on the BTL Rate Pages. We do have one Lender who will not require any evidence of rental income and will Allow you to 'Self Certify' that your income is sufficient for both your domestic And Buy To Let Mortgage.
