I'll second what JHAP said on the park models... I just got a good deal on a used 2005 model. Our plans are to use it as our weekend place for the next several years, and then live in it while we build our house. We are putting in all of the utilities now, and will be able to use them for the new house when we build it.

It's not huge, but at 12 feet wide and 37 feet long, with a sleeping loft for our two kids, and a private master bedroom, I think it will be very comfortable for this type of plan.

Here's a view of the interior....

And finally the view from the soon to be constructed front porch...



Good luck with your plans.
