Sounds like you are going to have to tack on the amount of down payment and closing costs to the amount of the purchase price. You don't say how much the settlement is, but let's guess it's 3%. If you purchase a house for $100,000, then add another $3000 for closing costs and another $2,250 for down payment, then the purchase price for your $100,000 house is now $105,250, but the seller is still getting $100,000. The house will have to appraise for $105,250. This is just a convoluted way of you borrowing your closing costs and down payment.
