One cannot control the outside forces (government/economy/career/medical/etc.). 

@Najeh Davenport I prefer multi-family because you have better control over appreciation.

Who is the human in the command and control seat?

Of course, if it is something outside your control that can be trickier to deal with. 

I only buy the basic machines with the dial controller, no electronic controls which makes it super simple to repair and simple to operate.

You should Google "Terminated Merchant File" (TMF) a/k/a MATCH (Member Alert To Control High Risk) prior to opting to not make good on a debt to your payment processor.

It tells me you really do want advice and likely want to commit and make a move. 100% need to get spending and credit card debt under control before there's even a thought about purchasing property. 

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

Put controls in place so that your rehab team can't hit you with a surprise bill, or misappropriate funds.

I'm not demeaning your position, I'm merely seeking an avenue in creating a fixed cost scenario while also having total control on how my tenants are handled.
