Refinancing makes sense when the savings or benefits outweigh the costs within the time you'll keep the loan. Old rules of thumb, like "only refinance if rates drop 1%," miss the details. Do the math on your loan.
Good Reasons to Refinance
- Lower your rate and monthly payment
- Remove mortgage insurance, for example moving from FHA to conventional once you have enough equity
- Shorten your term to pay off sooner and save interest
- Switch from an adjustable to a fixed rate before an adjustment
- Take cash out for renovations, debt payoff, or investing
- Remove a co-borrower, such as after a divorce
The Break-Even Test
Months to break even = closing costs ÷ monthly savings
Example: $6,000 in costs and $200 in monthly savings means 30 months to break even. If you'll keep the loan longer than that, the refinance pays off.
Watch the Total Cost Too
A lower payment can still cost more in total if you restart a 30-year term after paying for years. Compare total interest under both loans, or choose a term that matches the years you have left.
When to Wait
- You'll likely sell before you break even
- Your current rate is lower than today's rates and you need only a modest amount of cash; a HELOC may be cheaper
- An investment loan has a prepayment penalty that wipes out the savings
Refinancing a Rental
Investors can refinance with a DSCR cash-out or rate-and-term loan without income documentation, and check the prepayment penalty on the current loan first.
Refinance FAQ
How much do rates need to drop to refinance?
There's no fixed rule. Calculate your break-even point using actual closing costs and monthly savings.
Can I refinance with bad credit?
Possibly. FHA, VA, and some Non-QM programs are more flexible, but pricing depends heavily on credit.
Can I refinance an investment property without income documents?
Yes, with a DSCR rate-and-term or cash-out refinance.
