Loan to Value or LTV is the term used to calculate the amount of loan as a percentage of the value of the property. It is the maximum amount a lender will lend. LTV also affects the interest rate changed on loan. The high the LTV, the higher will be the interest rate. For example – if the value of a property is £100,000 and the lender is willing to lend £90,000 on that property. The LTV will be 90%.
