St. Louis homebuyers moved billions through the mortgage market last year, and a new 150-plus lender ranking shows which companies captured the biggest share of that business. The numbers offer a snapshot of a housing market that was active enough to generate major loan volume, but still constrained by affordability and limited inventory.
The top 20 residential mortgage lenders in the region originated $5.35 billion in home purchase loans during 2025, according to the St. Louis Business Journal. The publication's online ranking expands beyond the 20 lenders featured in print, giving a broader look at the companies financing purchases across the bi-state market.
This is a purchase-loan ranking, not a leaderboard for every kind of mortgage business. Refinances, cash-out refinances, home-improvement loans, multifamily mortgages and other purposes are excluded, meaning the list is focused specifically on lenders helping buyers acquire residential properties.
What The St. Louis Ranking Measures
The analysis covers a 14-county area in Missouri and Illinois, along with the city of St. Louis, and includes residential properties with four or fewer units. The Business Journal said the ranking was based on Home Mortgage Disclosure Act records and cautioned that it could not independently verify the information submitted for the list.
The underlying data became easier to access this year. The Consumer Financial Protection Bureau said 2025 HMDA loan-level records were released March 31 for approximately 4,768 reporting institutions, allowing researchers and news organizations to compare lender activity across markets.
For borrowers, however, a lender's size does not necessarily translate into the easiest path to approval. A broader analysis by St. Louis Fed economists found that owner-occupied purchase applicants had a 15.3% denial rate in 2024, compared with 12.7% for second-home applicants, with income, debt-to-income ratios and down payments playing major roles.
A Big Lending Year In A Complicated Market
The latest St. Louis Fed Beige Book described residential activity in St. Louis as mixed. One local real estate contact reported a very active market, including buyers making cash offers and waiving inspections, while a regional banker said new residential loan demand remained weak because of low inventory and poor sentiment in several markets.
Borrowing costs have kept that tension in place. The National Association of REALTORS® reported that the average 30-year fixed mortgage rate was 6.49% in June, while Midwest existing-home sales fell 3% from May but remained 2.1% above the year-earlier level.
That makes the $5.35 billion figure less a verdict on which lender is best than a measure of where St. Louis-area home purchases actually landed in 2025. With rates, inventory and underwriting standards still shaping who can buy, next year's ranking could look very different even if the region's housing market remains busy.
