I've been talking with John about an initiative that is intended to help communities improve their homeownership programs to preserve long term affordability. It is a peer network model called "Cornerstone Partnership", sponsored by NCB Capital Impact, through a grant from the Ford Foundation.
It is aimed at promoting best pracitces in the field of affordable homeownership. NACCED could join as a national outreach partner to promote the principles and share the various tools and services available. I've attached a fact sheet and more details are found on the webpage linked on the fact sheet.
NACCED may host a short webinar to inform you about the opportunity, and then discuss it further at our meeting in July and conference in September. Hope you'll take a look at this.
