In real estate terminology, you may hear about various ratios and where you need to fall within the ratio to qualify for the home you want. A ratio simply expresses a relationship between two values: they compare two things, so a student/teacher ratio might be shown as 18:1, or one teacher for every 18 students. Different ratios apply to residential home buyers, investors, sellers, and lenders, but here are a few that might apply to you.
Loan-to-value or LTV
A comparison between the amount of a mortgage loan and either the home’s purchase price (for new buyers) or its appraised value (in a refinance) is its loan-to-value ratio. Lower LTVs typically qualify a buyer or homeowner a lower interest rate because there is less risk of default to the lender. So, a conforming mortgage with 20 percent down often garners a lower rate than an FHA loan with only five percent down.
Higher LTVs place more risk on the lender so if the market drops, the home could be “upside-down” or worth less than the amount of the mortgage.
Debt-to-income ratio or DTI
More important to home buyers is the debt-to-income ratio. Also called a debt-service ratio, it expresses how much money the borrower makes monthly compared to the monthly ongoing debt payments and obligations. A lender uses this figure to determine how high a mortgage payment you can handle. The first number is your income (gross) from your job, plus any other income that can be counted such as child support or a trust disbursement that you can use to make your mortgage payment plus taxes and insurance, and if applicable, association dues.
The second number uses the same calculation as the first plus any long-term debt such as a vehicle or school loan and consumer debt. This amount is the percentage of your income used to pay housing and long-term debt. So, a ratio of 30:37 (also written 30/37) means you spend 30 percent of all your income on housing with no more than seven percent obligated to debt service. That leaves you with 63 percent of your income for food, auto insurance, medical bills, clothing, and other expenses. Qualifying ratios adjust over time, but the Federal Housing Administration lists the qualifying ratio and the formula to determine it to qualify for an FHA loan.
Your DTI comes from your personal debts and income, and the LTV comes from a specific home's value, but the price-to-income ratio expresses the affordability of housing in a given locale. Most often, it is the ratio of the median home price to the median household disposable income. This ratio helps you determine if the home you want to buy is overpriced (it will be hard to sell) or under-priced (super good deal) for its geographical location. Lenders use this ratio as one additional factor in determining risk for that specific home.
