The break-even test
Every rate-and-term decision comes down to one calculation:
Closing costs ÷ monthly savings = break-even months.
Example: $4,200 in costs and $175/month in savings is a 24-month break-even. If you'll keep the mortgage five more years, refinancing wins. If you might sell in 18 months, it loses — you'd still be paying for the refinance when you hand over the keys. Brian runs this test on every scenario before recommending anything.
The no-cost refinance trade-off
A "no-cost" refinance isn't free — the lender pays your closing costs in exchange for a slightly higher rate. You pay nothing at closing and the break-even is immediate, which is why it's the right structure when you expect to keep the loan only a short time, or when rates are falling and you may refinance again soon. If you'll keep the loan for many years, paying costs out of pocket for the lower rate usually wins. Both structures should be priced side by side, every time.
Refinancing to drop mortgage insurance
If your home has appreciated since you bought, a refinance to 80% loan-to-value or below removes conventional PMI. But check the cheaper alternative first: many loans allow PMI removal through a new appraisal on your current mortgage, with no refinance at all. If your rate is already good, that path can save thousands.
Shortening the term
Moving from a 30-year to a 15- or 20-year loan raises the required payment but cuts the total interest dramatically — often by more than half. The order of operations matters, though: max out employer retirement matches, keep an emergency fund, then accelerate the mortgage. A mortgage you can't make because everything is tied up in home equity is a fragile position, not a rich one.
Seasoning rules and timing
Most refinances require roughly six months of seasoning on your current loan before you can refinance again. Conventional programs also have waiting periods after major credit events. If you just closed a purchase or refinance, ask what's possible before assuming you're stuck.
What Brian needs to run your numbers
Your current rate, balance, payment, and the last four years of your plan — do you expect to move, pay off, or hold? With that, the comparison takes minutes, and you'll see the answer rather than be told it. If the honest answer is "stay put," you'll hear it. And if what you actually want is access to equity rather than a lower payment, read the cash-out and HELOC comparison first — the structure you choose matters more than a quarter point of rate.
