We found a house we would like to buy. The only problem is it has polybeutylene pipes. The seller is willing to pay at closing for the repiping job, but not before because he is afraid something will fall through with the closing. We are either going with a conventional or USDA loan. My mortgage person said you can not buy a house anymore without repiping it first because the loan appraisers always require it. My realtor says she does not think this is true because she has sold houses last year with it. I asked my mortgage person to double check. He came back later and emailed me that the under writer has told him it would have to be replace "if" the loan appraiser requires it. My question is, are loan appraisers now requiring polybeutylene pipes to be replaced before closing on a conventional or USDA loan? I want to get this figured out, so we can sign a contract this week and get on with it.
