I am wanting to buy a house that has polybeutylene pipes. My mortgage person told me loan appraisers require the pipe to be replaced before closing. I am using a usda or conv loan. My realtor said this has never been an issue for her. I asked my mortgage person to double check. He then said "if" the appraiser requires it, then it would have to be replaced. Do loan appraisers generally require this? The seller is willing to pay for it at closing, but not before closing. This house is in GA.
