How to Refinance a Mortgage: A Step-by-Step Guide for Homeowners

Refinancing means replacing your current mortgage with a new loan, usually to get a lower rate, change your term, or tap your home equity. Knowing how to refinance a mortgage can save you thousands, but only if the numbers work.

Timing matters. As of mid-September 2026, the average 30-year fixed rate was about 6.95%, up from 6.26% a year ago. This guide walks through the mortgage refinance process, refinance requirements, costs, and when refinancing pays off.

Why Homeowners Refinance

• Lower rate or payment. This is the classic reason, and it only helps if your new rate is meaningfully lower.
• Shorter term. Moving from a 30-year to a 15-year loan can cut total interest.
• Different loan type. Some homeowners switch from an adjustable rate to a fixed rate for stability.
• Dropping mortgage insurance. FHA borrowers often pay premiums for the life of the loan, and refinancing can end them if you have enough equity.
• Tapping equity. A cash out refinance turns equity into cash.

The Mortgage Refinance Process, Step-by-Step

Here’s how to refinance a mortgage from start to finish:

1. Define your goal. A lower payment, a shorter term, or cash in hand shapes which loan to pursue.
2. Check your numbers. Review your credit, home equity, and debt-to-income ratio.
3. Shop at least three lenders. Compare rates and fees using each Loan Estimate. Mortgage inquiries within a short window usually count as one credit pull.
4. Apply and lock your rate. Lenders send a Loan Estimate within three days of applying, and rate locks typically run 30 to 60 days.
5. Complete the appraisal and underwriting. Appraisals take a week or two (some streamline programs skip them),and underwriting can take 7 to 21 days. Avoid opening new credit.
6. Close. You’ll receive a Closing Disclosure at least three business days before signing, and primary-residence refinances generally include a three-day window to cancel.

The whole mortgage refinance process usually takes 30 to 45 days.

Refinance Requirements: What Lenders Look For

Refinance requirements vary by loan type, but most lenders check:

• Credit score: Conventional loans generally require 620 or higher, while FHA may accept scores as low as 580.
• Equity: Most lenders want at least 20% equity (an LTV of 80% or lower). FHA and VA programs are more flexible.
• Debt-to-income ratio: Under 43% is typical, though some lenders go up to 50% with strong compensating factors.
• Payment history and income: Late mortgage payments in the past 6 to 12 months can disqualify you, and lenders want documented, stable income.
• Cash for closing costs: You can pay them upfront or roll them into the loan.

How a Cash Out Refinance Works

A cash out refinance swaps your mortgage for a larger one and pays you the difference. To estimate your cash, multiply your home’s value by the lender’s LTV limit, then subtract your current balance.

For example, on a $400,000 home with $200,000 owed, an 80% LTV allows a $320,000 loan. That’s roughly $120,000 in cash before closing costs.

Cash out refinance requirements are stricter than for a standard refinance. Conventional loans typically cap at 80% LTV with 620-plus credit and about six months of seasoning. FHA also caps at around 80%, and VA loans can go higher.

Using the cash to pay off higher-interest debt or fund value-adding repairs is easier to justify than everyday spending, which just turns short-term costs into long-term debt. If your home is nearly paid off, a HELOC may fit better.

What Does It Cost, and When Does It Pay Off?

Refinance closing costs typically run 2% to 6% of the loan amount, or $6,000 to $18,000 on a $300,000 loan. To see if it’s worth it, calculate your break-even point: closing costs divided by monthly savings.

A quick example: A family with a $350,000 loan refinances from 7.25% to 6.25%. Their monthly principal and interest drops from about $2,388 to $2,155, saving roughly $233. With $7,200 in closing costs, they break even in about 31 months.

• Rule of thumb: Many lenders suggest a rate at least 1% lower, though some experts say 2%.
• Your timeline: If you’ll move before your break-even point, refinancing likely won’t pay off.
• No-closing-cost options: Rolling costs in or taking a higher rate means a bigger balance or bigger payments.

Now that you know how to refinance a mortgage and what it costs, run the math with your own numbers before committing.
