It Costs More to Borrow Less, Says Zillow Mortgage Analysis

The FINANCIAL -- Compared to borrowers with $400,000 home loans, borrowers with loans of $100,000 pay 10 percent more for every dollar borrowed due to higher interest rates and fees. Additionally, borrowers with small loan amounts have substantially fewer lenders willing to lend them money, according to an analysis of loan requests and quotes on Zillow Mortgages.

More than one-quarter of all U.S. homes would have a mortgage of $100,000 or less if 20 percent were put down on the home.

All things being equal, including credit score and loan-to-value ratios, borrowers with small loan amounts were offered more expensive loans compared to borrowers with high loans amounts. The average interest rate offered on a $100,000 home loan in the first quarter of 2015 was 3.95 percent with an APR of 4.06 percent. The average interest rate offered on a $400,000 home loan during the same period was 3.64 percent with an APR of 3.7 percent. The larger the difference between the interest rate and the APR, the more it costs the homebuyer per dollar borrowed.

Low loan amount borrowers also had limited options for their home loan. The typical borrower seeking a loan for $100,000 received half as many loan quotes from lenders compared to similar borrowers seeking loans for $400,000.

"Lenders go after big loan amounts and back-burner small loan amounts because even though they take the same amount of time to complete, the larger the loan amount is, the more a lender typically makes," said Erin Lantz, Zillow VP of mortgages. "Since there is less competition for small loan amounts, lenders offer higher interest rates to help cover the costs and many low-to middle-income borrowers have no choice but to pay more."

If a borrower with a $100,000 loan were offered the same interest rate and APR as a borrower with a $400,000 loan, they would save 4 percent per month or $7,560 over the life of a 30-yr fixed rate loan.

Even lower loan amounts of $50,000 were offered an average interest rate of 3.9 percent with an APR of 4.14 percent, and have 88 percent fewer loan quotes from one-sixth as many lender as similar borrowers seeking loans for $400,000. Loans for $50,000 cost an average of 12 percent more than loans for $400,000.
