That sounds horrible. I rented a house with the option to buy and as I saw more and more what needed to be done (eventual roof replacement, plumbing problems, etc) it scared me. I own a house now but it was DH's house before we were married. He's good at working on things and he knows the house very well - he grew up in this house. It's an old 1930's brick house and just to replace the windows is something like $30K

I am so sorry you're going through this but hopefully it'll get sorted out and will be a one time problem. The joys of being a grown-up, huh
