How to get started in affordable housing development?

[Matt J.]

I haven’t been able to find a lot of information out there on how someone would go about getting started in their first affordable housing development. 

I own a few places in Duluth, MN, and the city has a program where they offer up lots they own for free as long as the buyer is committed to building affordable housing on it.  

I am wondering how someone would get started with this type of development and how to still turn a profit.
