Appraisal & PMI drop

Extras

Current LTV: 75.3% · Under 80% — refi appraisal ($600) may drop PMI, saving $1,440/yr.

Assumes fixed-rate loans, no pre-payment penalty, and closing costs either paid out-of-pocket or rolled into principal. Lifetime savings compares remaining payments on the current loan against total payments on the new loan — a longer new term may lower your monthly even when it raises lifetime cost.
