How to Refinance Your Mortgage: When It Makes Sense and When It Doesn't

Refinancing replaces your current mortgage with a new one — ideally at a lower interest rate, better terms, or both. Done right, it can save you $200–$500 per month. Done wrong, it extends your debt and costs more than you save.

When Does Refinancing Make Sense?

• You can lower your interest rate by at least 0.5–1%
• You plan to stay in the home long enough to recoup closing costs
• You want to switch from an adjustable-rate to a fixed-rate mortgage
• You want to shorten the loan term (e.g., 30-year to 15-year)
• You need to eliminate PMI after reaching 20% equity

The Break-Even Point Calculation

Refinancing costs 2–5% of the loan amount in closing costs. Divide total closing costs by your monthly savings to find the break-even point. If closing costs are $4,000 and you save $200/month, break-even is 20 months. If you'll stay longer than that, refinancing wins.

The Refinancing Process

1. 1Check your credit score — 620 minimum, 740+ for best rates
2. 2Get quotes from 3+ lenders (banks, credit unions, online lenders)
3. 3Compare APR (not just interest rate) — it includes fees
4. 4Lock your rate once you're happy
5. 5Provide documents: income, taxes, bank statements
6. 6Close the new loan (usually 30–45 days)

Cash-Out Refinance: Powerful but Risky

A cash-out refinance lets you borrow more than you owe and take the difference as cash. Useful for home improvements or paying off high-interest debt. But you're converting unsecured debt to secured debt — default means losing your home. Use cautiously.
