What is LTV for HMO Mortgages?

Definition: LTV (Loan-to-Value) is the ratio of a mortgage loan to the value of the property being purchased or remortgaged, expressed as a percentage. It is a critical affordability and risk metric used by every HMO mortgage lender to set borrowing limits and price interest rates. A lower LTV indicates more equity and lower risk for the lender, which typically results in lower rates and a wider choice of products. For HMO mortgages, most mainstream specialist lenders will lend up to 75% LTV, meaning a minimum 25% deposit is required. Some lenders may offer up to 80% LTV for experienced landlords with strong portfolios, while others restrict to 65–70% for larger or more complex HMOs. The LTV is calculated against the lender's valuation of the property — not the purchase price — so an overvalued property can result in a lower loan offer than expected. When refinancing, a lower LTV achieved through capital growth or capital repayments unlocks better remortgage rates. Portfolio landlords must also consider aggregate LTV across their entire portfolio when applying for new finance.
