What Is a Mortgage Refinance?
Refinancing means replacing your existing mortgage with a new loan — typically to get a lower interest rate, change your loan term, switch from an ARM to a fixed rate, or access your home's equity. Your existing mortgage is paid off by the new loan; the new loan has its own terms, rate, and closing costs.
Refinancing can save significant money, but it's not free — closing costs typically run 2–5% of the loan amount (approximately $6,000–$15,000 on a $300,000 loan). The key question is always: how long until you recoup the closing costs through monthly savings?
Types of Mortgage Refinance
Rate-and-Term Refinance
Changes your interest rate, loan term, or both. No cash out. The most common type. Goal is to lower monthly payment, save on total interest, or pay off the loan faster. Lowest rates and easiest to qualify for.
Cash-Out Refinance
Refinances for more than you owe and takes the difference as cash. Uses: home improvements, debt consolidation, education, investment. Rates are typically 0.25–0.5% higher than rate-and-term. Requires sufficient home equity (usually 80% LTV max — keeping 20% equity after cash-out).
Cash-In Refinance
Brings cash to the table to pay down your balance — typically to reach 80% LTV (eliminate PMI), qualify for a better rate tier, or reduce monthly payment. Less common but makes sense in specific situations.
Streamline Refinance
Simplified refi programs for existing government-backed loans. FHA Streamline (FHA→FHA), VA IRRRL (VA→VA), and USDA Streamline all offer faster processing, reduced documentation, and often no appraisal required.
The Break-Even Calculation
The break-even point tells you how long you must stay in the home for the refinance to make financial sense. Formula:
Break-Even Months = Total Closing Costs ÷ Monthly Payment Savings
Example: $8,000 in closing costs ÷ $200/month savings = 40 months (3.3 years). If you plan to stay longer than 40 months, refinancing makes financial sense.

When Does Refinancing Make Sense?
Rate drop of 0.5–1%+ — The "1% rule" is a helpful benchmark, though even smaller drops can be worth it on large loans
Switching from ARM to fixed — Lock in predictability before adjustment period
Shortening loan term — Moving from 30 to 15 years to save dramatically on interest
Eliminating PMI — Refinancing once you have 20% equity to remove PMI if your lender won't cancel it directly
Cash-out for high-ROI use — Home improvements that increase home value, paying off high-rate credit card debt
You plan to stay past the break-even point
Refinance Qualification Requirements
Credit score: 620+ for conventional; 580+ for FHA streamline; no minimum for VA IRRRL
Equity: Most refinances require at least 3–5% equity (95% LTV max); cash-out typically caps at 80% LTV
DTI ratio: 45–50% for conventional; 57% for FHA
Income documentation: Same requirements as original purchase
Payment history: Most programs require no 30-day lates in the past 12 months
How to Get the Best Refinance Rate
Check your credit report and score before applying
Shop at least 3–5 lenders — online lenders often beat banks on refinance rates
Compare APR, not just interest rate — APR includes fees
Consider paying points to lower the rate if you plan to stay long-term
Get all loan estimates within a 45-day window (multiple hard pulls count as one)
Lock your rate once you find an acceptable offer — don't try to time the market
Frequently Asked Questions
Refinancing typically costs 2–5% of the loan amount in closing costs — about $4,000–$15,000 on a $300,000 loan. Main costs include lender origination fees (0.5–1.5%), appraisal ($400–700), title insurance ($500–1,500), and government recording fees. No-closing-cost refinances are available but roll costs into the loan or rate, so you pay more over time.
A standard refinance takes 30–45 days from application to closing, similar to a purchase mortgage. Streamline refinances (FHA, VA, USDA) can sometimes close in 20–30 days due to reduced documentation and no appraisal requirements. The main timeline drivers are the appraisal schedule and lender underwriting capacity.
There's no mandatory waiting period for conventional refinances — theoretically you can refinance the day after closing. However, most lenders require 6 months of seasoning (payment history) before approving a refinance. FHA streamline and VA IRRRL programs require at least 6 months of payments. Practically, refinancing within the first year is rare due to still being underwater on closing costs.
It depends on your closing costs and how long you'll keep the loan. If closing costs are $5,000 and you save $100/month, your break-even is 50 months (4+ years). If you plan to stay in the home for 7+ years, it's probably worth it. If you might move in 3 years, the math doesn't work. Run the numbers for your specific situation rather than following generic rules.
