Hello. I am in the middle of trying to get a FHA loan for a house that shares a septic with two neighboring houses. There are legal documents in place and everything seems sound. But there is no CO for the septic (it was dug when the house was built in the 30's). The appraiser keeps asking for more and more documents. There seems to be come confusion. Does anyone have experience in dealing with getting shared septics through FHA? Will this be allowed?
