It may not be too late for you to switch to a Down Payment Assitance program.There are a few factors we still need to address and I believe once you address them, you should know if it will work for you. You have entered into a contract and you have to make sure the Seller will agree to make changes to the agreement. Do you need additional closing costs for your Down Payment Assistance Program? If you do, the Seller may or may not agree to give you additional funds to cover your Down Payment Assistance. There is a possibility since you already have a deal, they Seller may have you add any additional closing costs to the purchase price. Do you have an agent? If you have an Agent, please have your Agent coordinate with your Lender and the Seller to best dictate how you can get your Down Payment Assistance. Try and negotiate the Down Payment Assistance before you start paying for inspections, you do not want to be out the money for the inspections if things do not work out.
