When Refinancing Actually Makes Sense
Refinance offers arrive every time rates twitch. Most of them are bad for you. Here's how to spot the ones that aren't.
Cal says: A refi isn't free, even when it's marketed that way. The closing costs always exist — they're either added to your loan balance or baked into a higher rate.
- Rate-and-term refinance. Replace your existing loan with a new one at a lower rate or different term. Goal: lower payment or pay off faster.
- Cash-out refinance. Borrow more than you owe and take the difference in cash. Goal: tap home equity for renovations, debt consolidation, etc.
- Streamline refinance. Available for FHA, VA, and USDA loans. Less paperwork, no appraisal in many cases. Goal: drop the rate quickly with minimal friction.
The only number that matters when evaluating a refi:
Breakeven months = Closing costs ÷ Monthly savings
Example: A $400,000 refinance with $8,000 in closing costs that drops your payment by $250/month has a breakeven of 32 months. If you plan to keep the home longer than that, the refi makes sense. If you'll move within 3 years, you'll lose money.
Old rule of thumb: 1% rate drop is "enough." That rule is decades old and ignores closing costs and how long you'll stay. Always run the breakeven instead.
Every refi resets your amortization. If you're 7 years into a 30-year loan and refinance into another 30-year, you've just turned a 23-years-left commitment into a 30-year one. You'll pay more total interest even at a lower rate.
Two ways to fix this:
- Refinance into a shorter term (15 or 20 years) instead of starting over at 30
- Keep paying your old higher payment on the new lower-rate loan — the extra goes straight to principal
Cash-out refis are aggressively marketed because lenders make more money on them. Be wary when the pitch is:
- "Consolidate your credit card debt into your mortgage." You're turning unsecured short-term debt into 30-year secured debt. The math can work, but a single missed payment now risks your house, not just your credit score.
- "Use your equity to invest." Borrowing against your home to buy stocks or crypto is the textbook setup for a forced sale in the next downturn.
- "No closing costs." The costs are either rolled into the loan balance (you finance them at your mortgage rate for 30 years) or hidden in a higher rate.
Cash-out refis can be smart for major home renovations that increase property value, or in genuine emergencies when no cheaper credit is available. They're rarely smart for lifestyle spending.
