Introduction
When it comes to refinancing a home loan, jumbo mortgages often stand out due to their larger loan amounts and stricter requirements. Unlike conventional mortgages, jumbo loans exceed the conforming loan limits set by Fannie Mae and Freddie Mac. Because of this, jumbo mortgage refinance rates can vary significantly, depending on the borrower’s financial profile, credit score, and lender policies.
This article will guide you through everything you need to know about jumbo refinance rates—how they work, what factors influence them, current market trends, and tips to secure the lowest possible rates.
What Is a Jumbo Mortgage?
A jumbo mortgage is a home loan that exceeds the conforming loan limits, which in 2025 are set at:
- $766,550 in most U.S. counties
- $1,149,825 in high-cost areas like parts of California, New York, and Washington D.C.
Any mortgage above these amounts is considered jumbo and is not eligible for purchase by Fannie Mae or Freddie Mac. Because lenders assume more risk, jumbo loans usually come with stricter requirements and slightly higher interest rates.
Why Refinance a Jumbo Mortgage?
Refinancing a jumbo mortgage can make sense in several scenarios:
- Lower Interest Rate: Reduce monthly payments and save thousands over the loan term.
- Switch Loan Type: Move from an ARM (adjustable-rate mortgage) to a fixed-rate loan for stability.
- Tap Home Equity: Cash-out refinancing allows access to equity for investments, renovations, or debt consolidation.
- Shorten Loan Term: Transitioning from a 30-year to a 15-year mortgage can help pay off the loan faster.
Jumbo Mortgage Refinance Rates vs. Conventional Rates
While jumbo mortgage refinance rates have historically been higher than conventional loans, competition among lenders has narrowed the gap.
Here’s a comparison:
| Loan Type | Average Rate (2025 est.) | Loan Limits | Typical Borrower Profile |
|---|---|---|---|
| Conventional Refinance | 6.25% – 6.75% | Up to $766,550 | Middle-income to high-income borrowers |
| Jumbo Refinance | 6.35% – 7.00% | Above $766,550 | High-income, strong credit borrowers |
👉 Key takeaway: Jumbo refinance rates are only slightly higher than conforming loans, but qualification standards are stricter.

Factors That Affect Jumbo Mortgage Refinance Rates
1. Credit Score
- A credit score of 740+ is typically required for the best jumbo rates.
- Lower scores (below 700) may still qualify but at higher interest costs.
2. Loan-to-Value Ratio (LTV)
- Lenders often require an LTV of 80% or lower for jumbo loans.
- Cash-out refinancing may require even lower LTV thresholds.
3. Debt-to-Income Ratio (DTI)
- Most lenders prefer a DTI below 43%.
- High-income borrowers with significant assets may get some flexibility.
4. Property Type & Location
- Primary residences usually get better rates compared to second homes or investment properties.
- Homes in high-cost states (CA, NY, MA) often have tailored jumbo refinance products.
5. Market Trends
- Jumbo refinance rates are influenced by the broader bond market, inflation, and Federal Reserve policies.

| Adjustable-Rate Jumbo (ARM) | Borrowers planning to sell/refinance in 5–7 years | Low initial rate, then adjusts | Lower starting payments | Risk of higher future rates |
