The tax credit works like an interest-free loan and must be repaid over a 15-year period.
no monthly payments due. Each year they can take the payment from your deductions. You can pay a 1$ for 14 years and the rest on year 15 if you wanted to.
If you sell the house, and make profit you must repay the loan with said profits.
If you sell the house, and DONT make profit, the remainder of the loan is folded.
It is a great get out of debt chance, or in my case get somewhat out of debt and build a garage on my land… and start a small shop.
