OP, as the mother of a young couple (well, half of it) who just bought a fixer-upper, I just want to say thank you for not looking to sell to a flipper.
My daughter and son-in-law bought a house like yours--the seller had been born in that house, which she inherited from her parents, the original owners, and it hadn't been at all maintained. There was water damage, scary wiring, frozen plumbing, missing floors, broken windows... But it was what they could afford in a town where they have compelling personal reasons to live, and they are doing the work to make it lovely again. Plus, the seller got more than she would have from a flipper, because buyers who will live in the house don't have to make a profit. And she's happy that another little girl (my granddaughter) will get to grow up playing where she did.
