Refi saves $310/mo but costs $7,400 — am I missing anything?
Synthetic scenario: current balance $438k, about 24 years left. New quote lowers P&I by ~$310/mo and costs $7,400 all-in. Simple break-even is ~24 months. Expect to stay at least 6 years. Besides resetting the amortization clock, what else belongs in the comparison?
