How to Refinance Your Mortgage: Step-by-Step Guide for 2026

Bottom line: Refinancing makes financial sense when the monthly savings exceed the closing costs within a timeframe you plan to stay in the home: the break-even point. A 1% rate reduction on a $400,000 mortgage saves roughly $200/month; if closing costs are $6,000, break-even is 30 months. If you plan to stay longer, refinance. If not, wait.

Quick answer

To refinance: check that current rates sit at least 0.5 to 1 point below your existing rate, apply with three lenders in the same window, compare Loan Estimates by APR, and confirm the break-even (closing costs divided by monthly savings) lands well inside your time left in the home. Costs run 2 to 5% of the loan amount, and the process takes 30 to 45 days from application to closing. The average 30-year conventional rate is currently around 6.72% APR. One caution: refinancing into a fresh 30-year term restarts your amortization clock, so match the new term to your remaining years or add extra principal payments.

Refinancing is a new mortgage that pays off your existing one. You keep the home; the lender changes. The goal is typically to reduce your interest rate, shorten the loan term, switch from an adjustable to a fixed rate, or access equity through a cash-out refinance. The average 30-year conventional rate we track is currently around 6.72%, and cash-out refinances typically price a bit above that, around 6.72%.

When Refinancing Makes Sense

Rate-and-term refinance: You lower your rate, change your term, or both. The test is simple: do the lifetime savings exceed the cost to refinance?

Cash-out refinance: You borrow more than you owe, taking the difference as cash. Useful for home improvements or consolidating high-rate debt, but resets your amortization clock and increases your loan balance.

ARM to fixed: If you have an adjustable-rate mortgage approaching its adjustment period and rates are rising, locking into a fixed rate eliminates future payment uncertainty.

Signs refinancing is worth exploring:

• Current rates are at least 0.5–1% below your existing rate
• You plan to stay in the home long enough to break even on closing costs
• Your credit score has improved significantly since origination
• Your home value has risen, removing PMI eligibility

The Break-Even Calculation

Break-even = Closing costs ÷ Monthly payment reduction

Example:

• Current payment: $2,400/month at 7.5%
• New payment: $2,180/month at 6.25% (saves $220/month)
• Closing costs: $7,500
• Break-even: $7,500 ÷ $220 = 34 months

If you plan to stay in the home more than 34 months, refinancing saves money. If you expect to sell or move within three years, closing costs likely outweigh the savings.

The Refinance Process: Step by Step

Step 1: Check your credit and finances Pull your credit reports. Your refinance rate depends heavily on credit score, so aim for 740+ for the best pricing. Calculate your home equity (current value minus remaining balance); you typically need 20% equity to avoid PMI on the new loan.

Step 2: Shop rates Apply to at least three lenders: your existing lender, one bank or credit union, and one online mortgage lender. Multiple mortgage applications within a 14–45 day window count as a single credit inquiry.

Step 3: Compare Loan Estimates Each lender provides a standardized Loan Estimate within three business days. Compare: interest rate, APR (includes fees), closing costs, and total interest over the loan life. The APR accounts for fees and is the best single comparison metric.

Step 4: Lock your rate Once you choose a lender, lock your interest rate (typically 30–60 days). Rate locks prevent the rate from changing while your loan is processed.

Step 5: Underwriting and appraisal The lender orders an appraisal (typically $300–600) and verifies your income, employment, and assets. Provide documents promptly, since delays extend your rate lock and can cost money.

Step 6: Closing You sign the new loan documents and pay closing costs (or roll them in). The new lender pays off your old mortgage. Your first payment on the new loan is typically due 30–45 days after closing.

Refinance Closing Costs

Expect 2–5% of the loan amount in closing costs:

Quick answers

How much does it cost to refinance? Typically 2 to 5% of the loan amount, or $8,000 to $20,000 on a $400,000 loan, covering origination, appraisal, title, and prepaid items.

How long does a refinance take? Usually 30 to 45 days from application to closing. Rate locks of 30 to 60 days cover the process.

Does refinancing hurt my credit? A small, temporary dip from the hard inquiry and new account. Shopping multiple lenders within 14 to 45 days counts as one inquiry.

Can I refinance with less than 20% equity? Yes, but expect PMI on the new conventional loan or FHA MIP. Some programs allow high-LTV refinances; the math needs the rate savings to cover the insurance cost.
