Home Ownership: Work with B-corp or volunteer realtor (reduced or no commissions) and Habitat for Humanity and/or North Bay Community Land Trust (HFH or NBCLT) to identify existing housing stock. Purchase at a fair market rate (100% or a charitable land purchase, i.e. 50% cost of home and 50% tax deduction for owner) using raised funds (e.g. Sonoma County Housing Fund, privately raised funds). Those funds could be donated directly to either HFH or NBCLT and restricted (directed) for the purchase of a particular housing unit.  Once purchased, HFH or NBCLT can rehabilitate to reach 'green' standards and habitability standards (i.e. electric appliances, new windows, insulation, water saving heater, solar, wiring) and then sell as a deed-restricted low to above moderate AMI cap.  Single Family Home lots could also have an ADU built (and potentially sold independently).

Multifamily Housing:  Work with Burbank, MidPen, SAHA, Eden, or a nonprofit affordable housing (NPO AH) developer working with <40 unit management  in the same manner as the home ownership model so that raised funds can be donated to one of these AH developers for rehabilitation and deeded affordable.
