@Evan Loader Not sure if you've tried these methods but i would try going to your local multifamily investor meets up, attending larger multifamily conferences and networking with Sponsors on social media platforms like BP and linkedlin. 

If the rents end up being taxable in the organization, they'll actually be subject to maximum income tax rates very quickly - much faster than if you just did this personally.There are groups now starting with "socially responsible" investing - effectively a standard partnership/syndicate that is "investing for good" - that would likely be a better structure to avoid 501(c)(3) headaches in a for profit venture.  

I always suggest spending a few months following several people on social media, that started a mastermind/STR course.

It's all over social media "I'm 30 years old and left my W2 from BRRRRing and using Other People's Money".

I've looked at California's market, and it looks a lot like the Canadian market, where the laws are made to protect the tenants and are not landlord friendly.

I envision this relationship as a two-way street—I'm eager to offer as much value as possible, like identifying potential properties for investment or helping with digital tasks (like websites and social media).I've recently set up my LLC here in South Carolina, but I'm somewhat unsure about the next steps, like where to find private money, locate properties, or structure owner financing for multifamily units.

The younger they are, the more important a social media search is.

Reviewing someone's social media and then changing your requirements is a Fair Housing trap.

Keep in mind many books are US-focused and some advice may not apply to Canadians - especially legal and tax topics.
