Account Closed is correct, absolutely do both.. especially if youre just starting out even Grant Cardone started with a SFR. but for the sake of his question lets say you have 100k saved up for a real estate endeavor TOTAL, and you find a SFR that fits the 1% ratio (100k house that brings in 1k rent) that is doable if you calculate it out that would equal a 8.2% cash on cash IF it stays at a 90% occupancy rate. on the other hand if you invest that 100k into a limited partnership with a company that invests in value add apartments will now your cash on cash can be a preferred 10% with a target of 16-20% IRR which would essentially double your money in 2-5 years.. in this scenario the SFR would take sweat equity from you and risk while only returning a measly 8% CoC while the MF would be completely passive allowing you to learn and grow without hindrance with a 10% CoCnow we are over simplifying but I hope this made sense.. cuz my brain hurts ;D

When companies or properties are not self sustaining, you would initiate an "owner contribution" to cover any expense the business/rental property could not cover. 

Throw an LLC together with a few people with $1m each, and buy it, San Francisco isn't short of folks who got lucky with this or that IPO and have the money, most of those tech companies have an unofficial employee-maintained slack/discord channel where they talk about real estate stuff.

Insurance companies can be liable for fair housing violations and penalties, though most will not want to admit it.
