Fannie Mae 20%

[JP Smith]

If I am buying a house for 20K, FNMA says I can't sell it for more than 20% in less than 90 days.  I have a buyer for 25K.  I am going to sell the seller some construction items to be included in the sale.  So, sale price 23,9999, with the sale of construction materials included of 1,001.00.   I am legitimately selling him over 1000 in retail of products to use on the house.  Does anyone have any suggestions or is this above board?
