We have cleaned out those tenants, and have security cameras, and access control pads to the courtyard to deter unwanted elements from coming by.

SFHs aren't under rent control.

"that was my point. if there was a storm in the area, then it's deemed an "act of god" and doesn't count against you, unlike something you could've been in control of. i.e., your home getting robbed.

Slow stable controlled growth of a portfolio lowers the risk as a broken furnace is spread across a greater cash flow base.  

Laws are different for less than 4 units and 4 and up on multifamily properties, and landlords have more control over their property for under 4 units.

If the primary unit is over 15 years old, in most areas in CA the primary unit is now rent controlled (which I believe is not what was intended by the 15 year exemption but is the way most jurisdictions are applying the 15 year exemption).  

Hello, I know this can be a very touchy subject due to fair housing laws but I just bought a property and one of the tenants wants to move to another floor and use RAFT, now I know I cannot deny them housing due to RAFT alone but they are applying because they told me they cannot come up with first last and security, I know RAFT will cover that but I am wondering what downsides are there for instance can RAFT enforce rent control or is it even more difficult to evict people who have applied.

If you can't keep control of your personal finances, you are highly unlikely to succeed in real estate investing.

You can still do something like you suggest, but maintain more control.

But I want to control where the money goes, not just into stocks and bonds.
