Mortgage Refinancing Guide

Refinancing can lower your interest rate, reduce your monthly payment, shorten your loan term, or provide access to equity. Whether it makes sense depends entirely on your numbers — and understanding those numbers is what this guide is for.

What Is Refinancing?

replaces your existing with a new loan. The new loan pays off the old one, and you begin repaying the new loan under different terms — typically a different , a different loan term, or both.

isn't always beneficial. Like your original , it involves , underwriting, and an appraisal. Whether refinancing saves money depends on how much you can reduce your rate, what closing costs you'll pay, and how long you plan to stay in the home.


Common Reasons to Refinance

Lower your interest rate

If rates have fallen since you bought, refinancing to a lower rate reduces both your monthly payment and the total interest you pay over the loan's life. This is the most common reason homeowners refinance.

Reduce your monthly payment

A lower rate or an extended loan term can reduce your monthly payment and free up cash flow. Be aware that extending your term — say, from 20 years remaining to a new 30-year loan — can increase total interest paid even with a lower rate.

Shorten your loan term

Many homeowners refinance from a 30-year mortgage into a 15- or 20-year loan when their income has grown. A shorter term builds equity faster and dramatically reduces total interest, though monthly payments are higher.

Switch loan types

Moving from an adjustable-rate mortgage (ARM) to a fixed-rate loan provides predictable payments. Converting from an FHA loan to a conventional loan may eliminate mortgage insurance once you have sufficient equity.

Access equity through cash-out refinancing

A cash-out refinance replaces your mortgage with a larger loan and pays you the difference in cash. It provides access to equity at mortgage interest rates, but increases your loan balance. Best suited for genuine financial needs or high-ROI home improvements.


Types of Refinancing

Most refinances fall into one of two categories:

Rate-and-Term Refinance

Changes your interest rate, loan term, or both. Your loan balance stays roughly the same. This is the most straightforward type — you're simply getting better terms on the existing amount you owe.

Best for: Lowering rate or shortening term

Cash-Out Refinance

Your new loan is larger than your current balance, and you receive the difference in cash. Your home secures the additional amount. The new loan typically comes with a slightly higher rate than a rate-and-term refinance.

Best for: Major expenses or home improvements

Cash-out refinancing increases your debt. Your home is the collateral. Use this option for genuine financial needs — home improvements with clear ROI, debt consolidation with a solid repayment plan, or significant expenses where mortgage rates are meaningfully lower than alternatives.


The Cost of Refinancing

Like your original , involves . These typically run 2–5% of the loan amount — meaning a $350,000 refinance might cost $7,000–$17,500 upfront.

Typical refinancing closing costs include:

  • Loan origination fees
  • Appraisal fee
  • Title search and title insurance
  • Recording fees
  • Prepaid interest and escrow deposits
  • Lender processing and underwriting fees

Some lenders "no--cost" refinances. These aren't actually free — the costs are either rolled into the loan balance or offset by a slightly higher . They can make sense if you don't plan to stay in the home long enough to recoup upfront closing costs.


Calculating Your Break-Even Point

The most important question in any decision is: how long will it take for your monthly savings to cover the cost of ? That's your break-even point — and you need to stay in the home past it for to be worth it.

Break-Even Calculation

Total closing costs$7,000
Monthly payment reduction$220
Break-even point32 months (~2.7 years)

In this example: if you plan to stay longer than ~3 years, refinancing makes financial sense. If you might move sooner, it likely doesn't.

The calculation is simple: divide total by your monthly savings. The result is the number of months until you break even. If you're confident you'll stay past that point, is likely worthwhile.

Model your current mortgage payments

The Mortgage & Ownership Cost Calculator can help you compare your current monthly payment to a potential refinanced payment so you can estimate your actual monthly savings.

When Refinancing Makes Sense

is worth exploring when multiple factors align. No single condition guarantees a is a good idea — it's the combination that matters.

Factors that support refinancing

  • Rates are meaningfully lower than your current rate (typically 0.75%+)
  • Your credit score has improved since you bought
  • You plan to stay in the home well past your break-even point
  • You want to eliminate mortgage insurance (PMI/MIP)
  • Shortening your term fits your financial goals

Factors that argue against

  • You might move before reaching the break-even point
  • You're far into your existing loan (resets amortization)
  • Your closing costs are high relative to monthly savings
  • Your financial situation has changed and you may not qualify
  • You're considering a cash-out for discretionary spending

Comparing offers from multiple lenders is essential. Interest rates, fee structures, and loan programs vary meaningfully between lenders, and the difference on a 30-year loan can be tens of thousands of dollars.

Refinancing is one way to accelerate equity building — either by reducing your rate (so more goes to principal) or by shortening your term. The Building Equity Guide covers all four ways equity grows. Read the guide →


What Should You Do Next?

Refinancing Checklist

  • Compare interest rates from multiple lenders
  • Calculate your estimated monthly savings
  • Calculate your break-even point (closing costs ÷ monthly savings)
  • Review all lender fees, not just the interest rate
  • Decide whether to keep or shorten your loan term
  • Confirm how long you plan to stay in the home
  • Consider whether a cash-out refinance is necessary and appropriate
  • Confirm refinancing aligns with your long-term financial goals

can be a meaningful financial tool — but it's not automatically the right call just because rates have dropped. Run your own break-even numbers, compare multiple lenders, and make sure the decision serves your long-term goals, not just this month's payment.
