Rate Disparities Persist Among Similar Borrowers in US Mortgage Market

Mortgage brokers are encountering notable discrepancies in interest rates, even among borrowers with comparable financial backgrounds. According to the Intercontinental Exchange's (ICE) August 2026 Mortgage Monitor, borrowers with nearly identical credit profiles are experiencing a substantial average spread of 38 basis points for conforming purchase mortgages. For a $300,000 loan, this variation translates into an added cost of around $76 per month.

Increased Costs with Government-Backed Loans

This difference in rates can accumulate to roughly $5,790 in additional expenses over the initial five years of a mortgage. For those utilizing FHA and VA loans, the rate spread extends even further, reaching 47 and 48 basis points respectively. The most significant disparities are seen among borrowers with lower credit scores, smaller loan amounts, higher loan-to-value ratios, and those opting for government-backed financing.

This trend is consistent with previous findings from Freddie Mac, which has been monitoring variations in rates among similar borrowers through its Loan Product Advisor tool. An analysis of 2022 data revealed that rate dispersion for similar borrower profiles has more than doubled compared to the average over the prior 11 years. Between 2010 and 2021, the spread remained below 20 basis points but surged to approximately 50 basis points during the months of October and November 2022.

Widening Gaps Highlighted by Studies

"The increase in rate dispersion means that consumers with similar borrower profiles are being offered a wide range of mortgage rates," remarked Genaro Villa, an expert in macro and housing economics at Freddie Mac. An earlier Federal Reserve Board study further emphasizes this issue, noting that once upfront points are considered, the gap can extend to 54 basis points between the 10th and 90th percentile mortgage rates for borrowers with identical characteristics on the same loans. This represents an average of about $6,500 in upfront costs for loans processed contemporaneously in the same market.

The study highlighted that variations could not be largely attributed to lender characteristics, as significant differences still existed even among loans issued by the same officer.

Home Prices and Equity Incrementally Rise

These findings are emerging amidst an unprecedented accumulation of wealth among mortgage holders. In July, mortgage holder equity reached an all-time high of $18 trillion, coinciding with the highest annual growth rate in home prices seen in the last 14 months. Year-over-year home price growth hit 1.5% in July, marking a significant increase for five successive months and the sharpest rise since mid-2023.

"Reaching $18 trillion in mortgage holder equity is an extraordinary milestone, reflecting the substantial wealth that American homeowners have generated," stated Andy Walden, head of mortgage and housing market research at ICE. He added that the spring market spurred growth in both prices and equity, although rising interest rates may temper ongoing acceleration in the latter half of the year.

This upward trend in equity is largely attributed to lower rates stimulated early in 2026 that spurred market demand, with previous summer pricing dynamics steadily falling out of analysis windows. Recent adjustments in pricing indicate a softening of one-month gains, suggesting that any future acceleration might be constrained.

Challenges for Specific Borrowers

Mortgage holders currently control $11.7 trillion in tappable equity, with approximately 47.5 million borrowers each holding an average of $212,000 in equity. However, not every segment is benefitting from this rise; about 813,000 mortgage holders find themselves underwater, marking a 44% increase year-over-year, primarily among FHA and VA borrowers who purchased properties during 2022 and 2025, particularly in Texas and Florida.

The report also highlighted unusually steep discounts on distressed properties, with bank-owned real estate properties being sold at a striking 27.5% discount relative to comparable sales in June, reflecting some of the largest price gaps witnessed in decades. The most significant markdowns were observed in Florida, Texas, California, and the Mountain West.

ICE's Mortgage Monitor gathers data from the company's extensive loan-level residential mortgage database, which it claims encompasses a majority of the US market.
