Mortgage pricing can vary dramatically even when borrowers appear identical on paper.
A recent case illustrates how this happens.
Two borrowers contacted BANKIRR within days of each other. Both were purchasing homes in the same price range with 20 percent down payments and credit scores above 760.
Borrower A received a quote of 6.625 percent with zero points from a regional lender.
Borrower B received 7.125 percent with zero points from a large national lender.
At first glance the difference appears small. But the spread between those two quotes is half a percent, which significantly affects the cost of the loan over time.
We analyzed both Loan Estimates to determine why the pricing diverged.
The answer was not credit, debt, or property type. The difference was entirely attributable to the lender’s internal pricing structure.
Large retail lenders often embed higher margins into their rate sheets to cover advertising costs, branch overhead, and commissioned loan officers.
Wholesale lenders operate differently. Their pricing is designed to be distributed through brokers who bring the borrower directly to the lender.
When we rebuilt Borrower B’s loan using wholesale pricing, the rate aligned almost exactly with Borrower A’s quote.
Original quote:
Rate: 7.125 percent
Points: $0
Monthly payment: $3,412
Rebuilt quote:
Rate: 6.625 percent
Points: $0
Monthly payment: $3,247
The difference is roughly $165 per month, or nearly $10,000 over the first five years of the loan.
This case highlights one of the most consistent findings in mortgage research.
The largest differences in mortgage pricing are often caused not by the borrower, but by the lender.
