Calculations based on the ZMG Buydown Calculator. Monthly subsidy equals the difference between the note-rate payment and the discounted-rate payment for each buydown period. Refund is calculated as total subsidy less the sum of monthly subsidies used through the number of payments made. This is an estimate — actual refund amounts may vary by lender and servicer. Property taxes, insurance, and MI/PMI are added directly to the discounted payment to show all-in monthly cost. Consult your loan officer for exact terms.
