Discount-points buydown breakeven

Should you pay discount points to buy down the mortgage rate? Compares the base-rate payment to the bought-down payment and reports the points cost (each point = 1% of the loan), the monthly saving, the months to recoup that cost (the breakeven), and the net saving if the loan is held to term. Deterministic; not lending advice.
