Simple calculation says I saved about $40,000 so far while living in a better environment and space. Buying a house in this area costs no less than $200,000 and land taxes come out to ~$500/month anyway.
I highly recommend mobile home living for just-married couples.
ps - our community does not allow people to rent their homes out, so everyone who lives here takes care of the property well. I suspect this may be an important feature for better quality of life in such a community. And there are no trailers -- all homes are stationary.
