Putting mobile on private land

[CJ Witmer]

A trusted friend is selling his mobile home. They’re building their forever home and the borough is saying there is a limit on dwellings on the lot. They currently have their residence, and two mobiles, so that’s why it’s for sale. It’s a very nice double wide (https://www.zillow.com/homedetails/7549-Talhelm-Rd-Chambersburg-PA-17202/78619029_zpid/?fromHomePage=true) My question is, has anyone moved a mobile to their own land and turned it into a rental? He called a local mover and they charge $7k-$9k for local moves and that includes complete tear down, split the home, pack it, ship it, set it back up, do all trim work inside, siding work outside, and ridge vent. Is be looking for a lot with water and sewer existing. What things should I be considering? We’d plan to rent for $900/month. I’m thinking if we could be “all-in” for $75k or less, this may be worth considering, but wanted some feedback. Thanks
