Haven't read other posts but thought I'd share this even tho you won't wanna hear it! A friend of ours bought an old house to Reno and wishes she never had bothered. The more they fixed the more issues they found and the cost of it has been blown completely out of proportion. But they have to do it now because they've started and they won't get anywhere close to what they paid for it selling a half renovated 100 year old house.
Sorry but I don't think I'd do it.
