When Does Refinancing Make Financial Sense?

In commercial and residential mortgage advisory, the conventional benchmark is the 1% Rule: if prevailing live market rates drop at least 0.75% to 1.00% below your existing promissory note rate, refinancing typically recoups closing expenses within 18 to 36 months.

1. Breakeven Timeline

Divide total closing fees (title insurance, appraisal, underwriting) by monthly payment reduction. If closing costs equal $4,000 and you save $200/month, your breakeven threshold is exactly 20 months.

2. Term Reduction Strategy

Refinancing from a 30-year into a 15-year fixed note accelerates principal amortization. While monthly payments may increase slightly, overall lifetime interest expenses drop by over 60%.
