Jumbo Loan Refinancing: What High-Value Homeowners Need to Know

If your loan balance exceeds the conforming loan limit set each year by the Federal Housing Finance Agency, you’re in jumbo loan territory. That threshold currently sits above $806,500 in most U.S. counties and higher in designated high-cost markets. Refinancing a jumbo loan follows the same basic steps as a conforming refinance — but the underwriting is stricter.

Jumbo refinance applicants typically need:

• A credit score of 700 or higher (often 740+ for the best pricing)
• Robust cash reserves, often 6 to 12 months of mortgage payments
• A debt-to-income ratio at or below 43%
• Strong documentation of income, assets, and property value

The upside: jumbo rates have narrowed considerably against conforming rates in recent years, and for high-balance borrowers even a small rate change translates into meaningful monthly savings. A 0.25% improvement on a $1 million loan saves roughly $2,500 per year.

If your home has appreciated and you’re carrying a higher-rate jumbo from years past, it’s worth running the numbers. The strict qualifying standards are real, but so are the savings for borrowers who meet them.
