Loan-to-value (LTV)
Plain definition. Loan-to-value (LTV) is a percentage that compares the size of a mortgage loan with the most recent valuation of the property the loan is secured on.
Technical definition. The Financial Conduct Authority’s MLAR Guidance calls it the “Loan to valuation ratio.” It is the loan divided by the most recent valuation of the property subject to the mortgage, multiplied by 100, so a £220k loan against a £250k valuation gives 88%. In the FCA’s residential loans to individuals FAQs, the loan for loan-to-value purposes is the amount of the reporting lender’s loan to the borrower plus the amounts of any existing loans to that borrower from other lenders and secured on the same property, and the valuation is the amount of the overall property valuation.
