My idea of a starter-home prefab community would be something like, small cottages packed in a community. Each cottage would have a drive-way to the side to park 1 car, a storage shed, and 1 street parking spot in front. The community would be built in a location where land is not to expensive and on a special 30-50 year co-ownership lease-purchase contract (for lack of better word).
First, the cottage homes would be relatively small and inexpensive, like these (but bigger):

The assumption is that 1-2 persons may be living in the cottage, and the minimum sq ft should be 250 (150 sq ft for 1st occupant + 100 sq ft for additional occupant). The cottages in the community would range from simple 250 sq ft with sleeping loft for 2, to 770 sq ft 2-story floor plans with 2 bedrooms upstairs. Space-saving appliances will be included in the purchase.
The co-ownership agreement is different from typical lease to own. The land owner agrees to a 30-50 year lease on the land and property, and the home purchaser pays a lump sum or enter lease agreement to occupy the property. If the purchaser opt for lease, he/she will make monthly payments at fixed rate for the 30-50 year duration, not unlike a 30-year fixed rate loan, but with no pre-payment option.
However, in 30-50 years, the agreement will end and the property will be torn down or removed. The home purchaser must vacate or remove the homes, but receives 30%-50% of the current market value of the land (paid by land owner), assessed by the county. The land owner then recovers the land for re-development.
Under the above scheme, the cottage community will only occupy the land for set period of 30-50 years. Afterwards it will be torn down and re-developed according to whatever that is needed in the future. The buyer is able to afford a small starter home with fixed payment for 30-50 years and the lease is transferable (and can be sold for a profit). Whoever end up with the property at conclusion of its lease period will walk away with 30%-50% of its land value, paid in lump sum cash. The land owner gets to maintain his/her ownership of the land, make a profit from lease payments through the 30-50 year duration, and take the land back at conclusion of the lease. In some ways, the home buyer and the land owner become business partners who share the risks and rewards of ownership, and not like the typical mobile home park lease.
