What a joke! This is his plan for affordable housing. It seems more like an admission of failure that he can't keep his promise to lower housing costs. It actually increases costs substantially when you factor in the interest. Not to mention when a home hits certain milestones it needs updates and expensive repairs sometimes unexpected. A lot of folks finance these repairs via home equity loans.
Hell with in 15 - 20 years most folks need a new roof, new heating and air and as I found out myself, if the building codes have changed since you purchased your home you will have to bring it up to code in order to sell it.
