welcome! it sounds like it would work out, but be sure you don't get a trailer that needs more work than the farmhouse you are renovating! the biggest worry usually seems to be floor rot. if you get one that has been sitting, you might get into more problems than you are wanting to. one big problem is infestation. remember that rats and mice carry diseases so you would need to clean accordingly. if you can find one with all the necessary working amenities that doesn't require extensive repair, you will learn to love it. good luck!
