Refinance, pay extra, or keep your mortgage?
Compare the cost during the time you expect to stay, the payoff timeline, and how much cash each path uses.
Start with the loan you have.
Use your latest mortgage statement. Principal and interest are enough for this comparison; taxes and insurance usually do not change between these paths.
What remains on your mortgage?
Add the offer and extra payment.

Your three paths, on the same clock.
Assumptions and calculation notes
Fixed-rate, fully amortizing loans with monthly payments. Extra principal is applied after the scheduled payment. Refinance starts now; rolled costs increase the new balance.
Holding-period cost = interest paid during the selected period + refinance costs paid or financed. Principal is not counted as a cost because it becomes equity; remaining balance is shown separately.
Taxes, insurance, HOA, PMI, maintenance, tax deductions, investment returns, and transaction costs at sale are excluded because they either do not differ between paths or require facts this short journey does not collect.
