a small set back. Don't lose sight of the prize. There are options. Mobile homes, heck even RVs. Don't knock it. You may have to go that route for a while. It is not the end of the world.
Independent land lords are an excellent idea. Tell them up front. They may jack the rent up a bit or ask for a bigger deposit.
Suggest telling them how much you like the place. then stroke them a little. Mention how you can see they are just the kind of landlord you want, because you can see by the excellent care and shape of the property they are doing a great job. Explain how it is just the right size, etc. Then explain your situation.
Try to make a new friend who is interested in helping you. you have nothing to lose.
