Affordable Housing and Housing Affordability are different things. Affordable Housing refers specifically to housing that is within the financial reach of families of low to moderate income. Housing Affordability refers to the idea that even for those families with medium to high income, high house prices in many areas renders homeownership out of their reach.
Both are important issues.
Housing Affordability is not a binary issue. Some families need just a little nudge to be able to get across the finish line to homeownership. @RookCapital's Shared Value Investment (tm) is designed to help with Housing Affordability by providing that bit of help families need. It could be the solution to your dream of homeownership.
