It is definitely a mess. I am glad you have an appointment with an attorney who can personally review everything for you. The members of this forum can only make guesses - and our guesses could be wrong.The paper work I guessing is going to show the overages went past the limit of the loan( sales price)and so the buyer is owed the money. The thing is I will be paying for those overages out of my pocket. So the customer will get an upgraded security system, windows. extended patio and here is the weirdest thing he will get. When we contracted to build they insisted on their own designer who was a relative. When the framing was complete there was a design flaw that required a $7,000 correction. The buyer argued that we we should of caught that mistake earlier. Rather than argue I agreed to pay for half. Now I am being told that his half is an overage that has to be paid back. Its one of the checks I received from him.
