Sunil, I bought a used mobile home home 7 or 8 years ago and put it on the property. Then it became a weekend place for the wife and I. I don't regret it but having 2 houses to maintain is about 5 times as much fun as having one. However, I wish I had done it years before when the kids were around.

I would recommend a trailer as an inexpensive alternative. You need to be warned that weekend time to use your property is going to be severely curtailed when kids get into weekend activities.
