The Loan-to-Value Ratio
The loan-to-value ratio is probably the most important of the underwritingratios. The loan-to-value ratio is defined as:
LTV ratio = Total Loan Balances (1st mtg + 2nd mtq + 3rd mtg) Fair Market Value of the Property
First let’s look at the numerator. If the borrower is only applying for a first mortgage, and there will be no other loans on the property, then the beginning balance of the new loan requested should be inserted in the numerator. However, if the borrower is applying for a second mortgage, then the “underwriter” (the person who determines whether or not the loan qualifies) should insert the sum of the first and second mortgages in the numerator. Similarly, if the borrower is applying for a third mortgage, then the underwriter should insert the sum of the first, second and third mortgages into the numerator.
When the borrower is applying for a second or third mortgage, the loan-to-value ratio is often known as the combined loan-to-value ratio (CLTV ratio).
Now let’s look at the denominator. Generally the fair market value of a property is determined by an appraisal. There is one important exception, however. When the proceeds of a mortgage loan are used to buy the same property that is securing the loan, then that mortgage known as a “purchase money loan”. If the appraisal comes in lower than the purchase price in a “purchase money” transaction, then the lender will use the LOWER of the purchase price or appraisal.
Mortgage brokers are often asked by real estate agents and buyers to base their loan on the appraised value rather than the purchase price. Their claim is that they have negotiated a super deal and that the property is worth much more than what they are paying for it. Perhaps so (but generally untrue), but lenders always base their maximum loan on the lower of purchase price or appraisal. The lender’s argument (it’s their money, so there is really very little argument) is that an appraisal is really no more than an estimate of fair market value, no matter how competent or conscientious the appraiser may be. The only true indicator of value is the marketplace in which “a willing buyer and a willing seller, each in full knowledge of the salient facts, and neither under undue pressure, agree upon terms”. If the property sells for “X”, then it is probably only worth “X”.
