Should you refinance in Missouri?
It comes down to your break-even. Take your closing costs (often 2-5% of the balance) and divide by your monthly savings — if you will stay in the home past that month count, refinancing usually wins. Cash-out makes sense when the rate and use of funds beat your other borrowing options.
