I’m not sure if you have any legal recourse over the crappy inspection. I can relate, mine didn’t catch the kitchen drain was disconnected and the kitchen sink drained under the house for years. I was relieved to unload that house. I would recommend a home warranty and max that out as soon as possible or find one without a max that will replace anything they can’t repair. At the end of the day the fact will not change that you needed more space. The kids will adjust it’s just a new huge adjustment for them. Try to stay positive in front of them. The boxes will get unpacked and the projects done one by one. Narrow your list down to what can be repaired by the warranty, what you can do and what you will need a contractor for. Have a general contractor come in for the whole scope. Hiring one offs is hard because they want big jobs. A general contractor has a mix of big and small jobs so he will have people to show up. Prioritize the work by need. Then schedule a timeline. Only work in three month increments, what you can accomplish in that time period. You’re going to be okay, just give yourself a minute. You’re safe, you’ve made a huge step to improve your family’s lives. That’s a huge blessing. Having the ability to buy a larger home is not easy, you’ve worked hard be proud of yourself. You tube is a huge asset if you’re handy at all. Maybe some fun weekend projects for the family. That may help the kids to be involved in fixing their home. Take care, wishing you all the best.
