57% of Purchase Borrowers Received Mortgage Rates Under 4% Last Week

Homebuyers could have seen median lifetime savings of $53,506 in interest on a $300,000 loan by comparison shopping for the best mortgage rates.

Aug. 27, 2019 — Charlotte, N.C.

Each week, LendingTree reports how much consumers can save by comparing rates during the loan-shopping process. We describe these savings in two ways, to provide the most detailed data possible on mortgage rates. The LendingTree Mortgage Rate Distribution details the range of mortgage interest rates on offer. The Mortgage Rate Competition Index is the median spread between the lowest and highest APRs offered by lenders in our marketplace.

For the week ending Aug. 25, 2019, the share of borrowers with rates under 4% was 57.2%.

Mortgage Rate Distribution

  • For 30-year, fixed-rate mortgages, 57.2% of purchase borrowers received offers under 4%. That is down from 57.96% of borrowers the previous week. A year ago, almost no offers were under 4%.
  • Across all 30-year, fixed-rate mortgage purchase applications on LendingTree, 3.875% was the most common interest rate. This rate was offered to 14.8% of borrowers.
  • Of 30-year, fixed-rate mortgage refinance borrowers, 61.9% received offers less than 4%, which is down from 62.8% the previous week. A year ago, virtually no refinance offers were under 4%.
  • Across all 30-year, fixed-rate mortgage refinance applications, the most common interest rate was 3.75%, offered to about 19.9% of borrowers.

Mortgage Rate Competition Index

  • Across all 30-year, fixed-rate mortgage purchase applications on LendingTree, the index was 1.12, down from 1.16 the previous week.
  • How big of a deal is it to get a mortgage APR that’s 1.12 percentage points lower than the competition? Over 30 years, that could translate to $53,506 in savings on a $300,000 loan (see Mortgage Savings Tracker graphic below).
  • The index was wider in the refinance market at 1.21, down from 1.29 the previous week. Refinance borrowers could have saved $57,684 by shopping for the lowest rate.

Other findings

  • The distribution of rates — and, as a result, the Mortgage Rate Competition Index — has widened as rates increased, reflecting how mortgage lenders may change the rates at which they can offer consumers loans, depending on their unique business circumstances.

About the Mortgage Rate Competition Index

The LendingTree Mortgage Rate Competition Index is a proprietary measure of the dispersion in mortgage pricing. It measures the APR spread of the best offers available on LendingTree relative to the least competitive (i.e., the highest) rates on 30-year, fixed-rate mortgages. Our research shows that mortgage rate competition varies with the financial and operational measures of activity in the mortgage markets. More details on the index are available in a white paper on LendingTree’s website.

How the index is formulated

A mortgage shopper enters their information on LendingTree.com. They input loan variables, including the proposed amount and down payment, and property variables, including property type and location. Using our proprietary algorithm, LendingTree matches borrowers with lenders based on the criteria they provided. Interested lenders return a rate and fee offer. For our index, we combine the rate and fees into an APR and calculate the spread as follows:

The spread is the difference between the highest and lowest offers, in this example, 4.62-4.21=0.41. We repeat this calculation across 30-year, fixed-rate mortgage loans that week and then find the median of the individual spread, which is our index value for that week. This is done separately for the population of purchase and refinance loan requests.
