Refinancing replaces your current mortgage with a new one, usually at a lower interest rate. Done at the right time, it can save you thousands. Done wrong, it costs more than you save. Here is how to decide whether it makes sense and how to do it.
When Does Refinancing Make Sense?
The classic rule of thumb is to refinance if you can lower your rate by at least 1%. That is a useful starting point, but the real question is whether you will recoup the closing costs before you sell the home.
Use this breakeven calculation: divide your closing costs by your monthly savings. The result is how many months it takes to break even. If you plan to stay in the home longer than that, refinancing makes sense.
Example: $5,000 in closing costs, $200 per month in savings = 25-month breakeven. If you plan to stay at least 25 more months, refinancing is worth it.
Types of Mortgage Refinancing
Rate-and-Term Refinance
This is the most common type. You keep the same loan balance but change the interest rate, the loan term, or both. You might refinance from a 30-year loan to a 15-year loan to pay it off faster, or lower your rate while keeping the 30-year term to reduce monthly payments.
Cash-Out Refinance
You take out a new mortgage for more than you owe and receive the difference in cash. Useful for home improvements, paying off high-interest debt, or other large expenses. The downside: you are adding to your loan balance and will pay interest on the full amount for years.
Cash-In Refinance
You bring cash to closing to pay down your balance, which can help you qualify for a better rate, eliminate private mortgage insurance, or get off an FHA loan that requires lifetime mortgage insurance.
Streamline Refinance
Available for FHA and VA loans, streamline refinances require less documentation and no new appraisal in many cases. They are designed specifically to lower your rate quickly with minimal paperwork.
What Credit Score Do You Need to Refinance?
Conventional refinance loans typically require a 620 minimum credit score. The best rates go to borrowers with 740 or higher. FHA streamline refinances can be done with lower scores since no new underwriting is required.
How Much Equity Do You Need?
For a rate-and-term refinance, most conventional lenders require at least 5% to 20% equity. For a cash-out refinance, you generally need to keep at least 20% equity in the home after the cash-out, meaning you can borrow up to 80% of the home’s value.
If you have less than 20% equity, you will pay private mortgage insurance, which adds to your monthly payment and reduces your savings.
Closing Costs for a Refinance
Refinance closing costs typically run 2% to 5% of the loan amount. On a $300,000 loan, that is $6,000 to $15,000. Common costs include:
- Loan origination fee: 0.5% to 1% of the loan amount
- Appraisal: $300 to $600
- Title search and insurance: $500 to $1,500
- Attorney or settlement fees: $500 to $1,000
- Prepaid interest and escrow setup
Some lenders offer no-closing-cost refinances where the fees are rolled into the loan or covered through a slightly higher rate. This works well if you plan to sell in a few years and do not want to pay thousands upfront.
Step-by-Step: How to Refinance
Step 1: Check Your Credit Score and Report
Pull your credit reports from all three bureaus and dispute any errors before applying. A few extra points on your score can save you thousands over the life of the loan.
Step 2: Calculate Your Home’s Equity
Get a rough estimate of your home’s current value using tools like Zillow or Redfin, then subtract your remaining loan balance. This gives you your approximate equity position and tells you which loan programs you qualify for.
Step 3: Shop at Least Three Lenders
Rates vary more than most borrowers realize. Get loan estimates from your current lender, at least one other bank, and a mortgage broker or online lender. All quotes should be for the same loan type and term so you can compare apples to apples.
Multiple mortgage inquiries within a 14 to 45-day window count as a single inquiry on your credit report under FICO scoring models. Shop aggressively during this period.
Step 4: Lock Your Rate
Once you choose a lender, lock your interest rate. Rate locks typically last 30 to 60 days. Ask about the cost of a float-down option that lets you capture a lower rate if rates drop before closing.
Step 5: Submit Documentation
Gather two years of tax returns, recent pay stubs, bank statements, and your current mortgage statement. Self-employed borrowers need additional documentation of business income.
Step 6: Appraisal and Underwriting
The lender orders an appraisal to confirm the home’s value. Underwriting reviews your full financial picture. Respond quickly to any requests for additional documents to keep the process moving.
Step 7: Close
At closing, you sign the new loan documents and pay closing costs. Your new loan pays off the old one. If you are doing a cash-out refinance, you receive funds a few days after closing once the rescission period expires.
When Not to Refinance
Refinancing is not the right move if you plan to sell soon and will not break even on closing costs. It also does not make sense if you have paid off most of your current loan already, because early mortgage payments are mostly interest. Refinancing late in a loan term resets that amortization clock.
How Long Does a Refinance Take?
Most refinances take 30 to 45 days from application to closing. Streamline refinances can sometimes close faster. Delays usually come from appraisal scheduling or slow document processing.
