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.

@Greg Strunak have you tried the anti-barking devices they sell online?

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

Stay in control whatever you decide. 

But as your portfolio builds bigger and the property management company charges per property and not per portfolio, I would think having your own team gives you a better sense of control or a better overview of your properties wouldn't it? 

If I default, they will get their house back.I control every step of the process.
