I'm a part-time CFO (Chief Financial Officer) for real estate developers across the country, most of whom are trying to give back to their communities through their real estate development skills.I'm also a former Director of Lending for a CDFI that lent money to local developers rebuilding LMI and under invested communities.

Meetup.com is a good resource for those but some of the groups will also post here on Bigger Pockets Marketplace too.

YouTube is also a fantastic resource—it's free and you can learn at your own pace, which is a huge benefit.
