3-2-1 Mortgage Buydown FAQs
What happens if I sell before the 3 years are up?
Any unused funds in the buydown escrow account are typically returned to whoever paid for the buydown (seller, builder, or you). You don't lose the money.
Can I refinance during the buydown period?
Yes, you can refinance at any time. If you refinance, the buydown ends and any remaining funds are returned. This is actually a common strategy if rates drop significantly.
Do all lenders offer 3-2-1 buydowns?
No, not all lenders offer this program. It's more common with larger lenders and mortgage brokers who work with multiple lenders. Shop around to find lenders who offer buydown programs.
Is the buydown cost tax deductible?
Yes, the buydown cost is generally treated as prepaid mortgage interest and may be tax deductible. Consult with a tax professional for your specific situation.
What's the difference between 3-2-1 and 2-1 buydowns?
A 2-1 buydown only lasts two years (2% reduction year 1, 1% reduction year 2). It costs less but provides fewer years of savings. Choose based on your cash flow needs and budget.
Can I combine a buydown with other loan programs?
Yes, 3-2-1 buydowns can typically be used with FHA, VA, conventional, and other loan programs. Check with your lender for specific program compatibility.
