Refinancing a $1,000,000 mortgage is very different from refinancing smaller, conventional loans. At this loan size, you’re often dealing with a jumbo mortgage — though in some high-cost areas, this may still fall within conforming loan limits.

So the key questions become:

👉 How much does it cost to refinance a $1M mortgage?

👉 What qualifications do lenders require?

👉 Is it worth it at this loan size?

On a $1M mortgage, even a 0.25% difference in rate can cost—or save—you tens of thousands. The problem? Most borrowers never see the true cost of their loan. This guide breaks down the full cost structure, jumbo loan requirements, and the steps you’ll need to qualify — all in an easy-to-understand Fincast format.

Key Takeaways

✅ Refinancing a $1M mortgage usually costs $20,000–$40,000+

✅ Jumbo refinance requirements include higher credit, lower DTI, and strict documentation

✅ Discount points can add $10,000–$20,000+ in extra cost

✅ Strong borrowers may qualify for competitive jumbo rates without points

Total Cost to Refinance a $1 Million Mortgage

Here’s a clear breakdown of common refinance expenses, which vary by location and loan program.

Typical Refinance Costs — $1,000,000 Loan

• Always compare APR—not just the interest rate—since it reflects the true cost of fees and points. Rates, costs, and savings vary by borrower, loan type, and market conditions.

Cost Breakdown: Why Jumbo Refinances Are More Expensive

Let’s break down each fee, especially important for high-balance loans.

1. Lender Fees ($3,000–$7,500)

These fees are sometimes higher than conventional loans, since jumbo loans require more manual review.

Includes:

• Underwriting

• Origination

• Processing

• Administration

2. Appraisal ($600–$1,200)

High-value homes require jumbo-level appraisals, sometimes with:

• Additional comps

• Complex property analysis

Appraisal waivers are less common at this loan size but may still be available in certain cases.

3. Title Insurance & Settlement ($3,500–$6,500)

Higher loan amounts = higher title premiums.

Includes:

• Title search

• Lender’s title policy

• Escrow/settlement

• Notary fees

Varies significantly by state.

4. Discount Points (Optional: $10,000–$20,000+)

On a $1M loan:

• 1 point = $10,000

• 2 points = $20,000

Many lenders advertise lower jumbo rates that require points. Always check your Loan Estimate.

• Costs can vary depending on whether this is a conforming high-balance loan or a jumbo loan.

Jumbo Loan Requirements: What You Need to Qualify for a $1M Refinance

Refinancing a $1 million mortgage means meeting stricter jumbo underwriting standards.

Here’s what lenders typically require:

1. Credit Score: 700–740+ Required

Higher score = better jumbo pricing.

• Minimum: 700

• Best pricing: 740–760+

2. Debt-to-Income Ratio (DTI): 36%–43% Max

Jumbo lenders rarely allow high DTI.

You’ll need:

• Stable income

• Low monthly obligations

• Strong reserves

3. Cash Reserves: 6–12 Months

Most jumbo programs require months of mortgage payments saved.

Example:

• PITI of $7,000 → you may need ~$42,000–$84,000 in reserves.

4. Loan-to-Value (LTV): Typically ≤ 80%

Most jumbo lenders require:

• 20% equity

5. Documentation Requirements

Expect to provide:

• 2 years of tax returns

• 2 years W-2s/1099s

• 60–90 days bank statements

• Asset documentation

• Proof of reserves

Jumbo loans require full documentation — limited-doc is nearly impossible.

Is Refinancing a $1M Mortgage Worth the Cost?

It can be, if:

✔️ You can lower your rate by 0.5%–1.0%+

Even a small rate drop on a $1M loan saves thousands of dollars over the loan term.

✔️ You’re removing PMI

If your loan is conforming and you have less than 20% equity, refinancing may help remove PMI.

✔️ You plan to stay for 3+ years

If your break-even period is short, staying in the home for 2-3 years may allow you to reap the savings after paying off the costs.

Break-even formula:

Divide your total closing costs by your monthly savings to estimate how long it takes to recover the cost of refinancing.

✔️ Total interest savings exceed refinance costs

A 1% drop can save tens of thousands of dollars over the life of the loan.

How to Calculate Your Total Refinance Costs (Step-by-Step)

Step 1: Collect a Loan Estimate

This shows your costs line by line.

Step 2: Add lender + title + appraisal + recording fees

These are your true closing costs.

Step 3: Look at discount points

Often hidden in Box A of the Loan Estimate.

Step 4: Include state mortgage taxes (if applicable)
