Husband wants to move his pregnant daughter into our house.

My husband has a 19 year-old daughter from a previous relationship. She's 22 weeks pregnant, single (father is in jail), and unemployed. Apparently she reached out to him last week and asked if she could move in with us in order to "start over."I'm skeptical of her reasoning. She currently lives in a tiny house with her mom, grandmother, and mother's boyfriend. We live in a large home in a much nicer area. I'm thinking she's under the impression she and the baby will have their own rooms, bathroom, access to our vehicles, etc. I'll add that this house was built by my father and grandfather, I inherited it about five years ago.She's lived with us before and it was a nightmare. Granted it was two years ago but I have no reason to believe she's changed. She dropped out of college and got pregnant by a loser who is now in jail. She hasn't worked in over a year and has no plans to get a job because she's pregnant and claims nobody will hire her right now.When she lived with us before she constantly caused problems, there were fights almost daily, and she was a terrible example for our two children (ages 8 and 10 now). She came home stoned and/or drunk often. She would sneak out and sneak friends (including boys) into our home overnight. She would fly into a rage at the first sign of consequences for her behavior. She once smashed a bathroom mirror because she found out we were planning to disconnect her cell phone after she failed every class one semester (due to constantly skipping school and putting no effort into her assignments).I think she wants to live a nice, comfortable, easy life with her baby in my house (rent free, of course). I don't buy her story about "starting over" one bit, not without tangible proof she's actually trying to improve her situation. She could be in school or attending a vocational training program if she truly can't find work, for example.My husband feels incredibly guilty because our two kids have a different life (he says "better") but it's not like his daughter had it that bad. She was always welcome to live with us but preferred her mom because she was given more freedom and got away with nearly everything there. She didn't like that we had rules and high expectations. I don't think my kids (or me or my husband) should be subjected to her or forced to put up with her and newborn because my husband feels like he didn't do enough earlier on.What's your take? Am I being unreasonable for having doubts? via /r/Parenting http://ift.tt/2rDA3xu
