Total Cost to Refinance a $400K Mortgage

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

Typical Refinance Costs — $400K Loan

• Always compare APR—not just the interest rate—since it reflects the true cost of fees and points.

Cost Breakdown: What You're Paying For

Let’s look at each refinance cost in detail.

1. Lender Fees ($1,500–$3,500)

These include:

• application fee

• underwriting

• origination

• admin and processing fees

Some lenders waive these entirely; others charge thousands.

2. Appraisal ($450–$700)

This determines your:

• Home value

• Equity

• Loan-to-value ratio (LTV)

3. Title Insurance & Settlement ($1,400–$3,000)

Covers:

• Title search

• Lender’s title insurance

• Escrow/settlement

• Notary fees

Costs depend heavily on your state and loan amount.

4. Credit Report ($25–$75)

A standard fee that all lenders charge.

5. Recording Fees ($50–$200)

County-level fees to record your new mortgage.

6. Prepaid Costs ($500–$3,000)

These are not “fees,” but still impact your cash-to-close:

• Prepaid interest

• Property taxes

• Homeowners insurance escrow

Refinancing changes the timing of escrow deposits.

7. Discount Points (Optional — $0–$8,000+)

One point = 1% of the loan amount.

On a $400k mortgage:

• 1 point = $4,000

• 2 points = $8,000

Points lower your interest rate but increase the upfront cost.

How to Reduce Refinancing Costs on a $400K Mortgage

✔️ Avoid discount points

Many low-advertised rates require points, which increase your closing costs and lengthen your break-even period.

Break-even point = Total refinance costs ÷ Monthly savings

✔️ Ask multiple lenders for fee breakdowns

Some charge $0 origination fees, which lowers your closing costs and shortens your break-even period.

✔️ Ask about appraisal waivers

If you have strong equity, you may not need a formal appraisal.

✔️ Request lender credits

Lender credits reduce your upfront cost in exchange for a slightly higher rate.

✔️ Ask title companies for reissue rates

If you bought your home recently, you may qualify for reduced fees.

💡 Pro Tip: A lender offering a slightly higher rate but $2,000–$4,000 fewer fees may be the better deal. Run the numbers with a program like Fincast to see which option makes more sense.

Can You Roll Refinance Costs Into the Loan?

Many lenders allow you to roll refinance costs into the loan, but be sure to look at the total cost of the loan over the term to see if it’s the right move.

Example:

Rolling $10,000 into a $400k refinance = $410,000 new loan balance.

Pros:

• Lower upfront cost

• No need for cash at closing

Cons:

• Slightly higher monthly payment

• Slightly higher long-term interest

Is Refinancing a $400K Mortgage Worth the Cost?

Refinancing may be worth it if:

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

Savings are often in the $100–$300+ range per month, depending on loan terms.

✔️ You can remove PMI

Saves $200–$400/mo, on average, but it depends on your loan size, credit score, and PMI rate.

✔️ You plan to stay in the home for 2–3+ 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.

✔️ Your total interest savings exceed refinancing costs

A 1% drop can save tens of thousands of dollars over the life of the loan — in some cases, $90,000+, depending on loan terms.

How to Estimate Your Refinance Costs (Step-by-Step)

Step 1: Get a Loan Estimate from a lender

When you apply for a loan, the lender must issue a Loan Estimate within three business days. This disclosure breaks down your costs so you can compare loans apples to apples.

Step 2: Add lender fees + title fees + appraisal

These represent your true closing costs.

Step 3: Check for discount points

Discount points increase your closing costs, lengthen your break-even, and may make or break whether the refinance is worth it.

Step 4: Add state mortgage taxes (if applicable)

Step 5: See how your offer stands using Fincast

Fincast allows you to see various offers from lenders to determine which makes the most financial sense.

Bottom Line

Refinancing a $400,000 mortgage typically costs $8,000–$20,000, depending on lender fees, appraisal requirements, and discount points.
