That's what I do and depending on how much cash flow you're looking for, you could do the same.By the way, there is a way to get really impressive COC if you are willing to accept some delayed gratification and possibly tap into the equity you have in your CA properties.If you are interested, feel free to DM me

Recently, more states have adopted protections based upon sexual orientation and gender identity, for example.

I've been investing/trading stocks for a long time and trust me when I say that losing money hurts a lot more than the gratification of making money.

True freedom isn't buying 5-6 houses and hoping for the best, it's a combination of suffering(by eliminating expenses, material items, immediate gratification areas) and betting on quality growth(delayed gratification, asset accumulation, perseveration, etc.) and managing the tail and head winds that come with this. 

Smaller house, cheaper cars, delayed gratification.

The Fair Housing Act is what applies to privately owned property (with the exceptions Bruce listed above) and it forbids discrimination against prospective tenants because of their disability as well as race, religion, sex (including gender identity and sexual orientation), skin color, familial status, and national origin. 

I think a more prudent (and achievable goal, not to mention far less financially risky) would be to start free classes/seminars to teach them how to delay gratification, increase their education and earnings potential, find quality and affordable child care (perhaps creating a "swap group" within your group for free trade-off CC), learn how to properly manage finances, and all of the other tools needed before you can even begin to invest in real estate.
