The effort to provide affordable housing by government/developer partnerships is a good idea...I purchased an affordable fee-simple house/land provided through such an agreement with the stipulation that I could not sell or rent within 10 years of purchase. The value of the house decreased with age, while the land increased in value 4Xs its purchase price in 30 years.  Now if the land was leased....?  Whole lot of difference in the math.  And there's the equity that could be channeled into the purchase of a new home without the tax penalties.
