Key insights
Rate drop: 1.00 percentage points
Strong drop — the historical refinance trigger threshold is ~0.5-0.75 points. You're comfortably past it.
Term reset is the hidden cost
Refinancing to a NEW 30-year loan after 5 years in the original 30-year resets the amortization clock — you'll pay 5 extra years of interest. Consider refinancing to a SHORTER term, or keep paying your old monthly amount after refinancing.
Watch for "no-cost" refi traps
Lenders advertising "no closing costs" typically bake those costs into a 0.25-0.5% higher rate. Often more expensive than paying closing costs upfront.

Refinance — but consider a shorter term
High priorityInstead of a new 30-year, ask for 15 or 20 year. Better rate, less total interest, and you don't reset the amortization.
Impact: A 15-year typically gets a rate 0.25-0.5% lower than 30-year, and you cut ~60% off lifetime interest.
Shop at least 3 lenders
Medium priorityRate quotes are free and don't hurt your credit if pulled within a 14-day window. A 0.125% rate difference is worth thousands.
Confirm property hasn't lost value
Medium priorityLenders require appraisal. If your home value dropped, you may need to bring cash to closing or face PMI on a refinance you didn't expect.
