Without living in it it's not house hacking, just regular REI.

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

You would probably be better off investing in REITs or a income fund for security and higher returnes.

I don't know the laws around returning the security deposit.

I went to set up the Security Deposit account with my wife and I as the custodian and them as the owners, and I hit a little roadblock.The bank only allowed 1 custodian and 1 owner.

What if that could all be securely automated?

But it really does not matter how you aquire these assets if you do it yourself or buy through a company that specializes in flipping investment properties and may have in house management to keep everything under one roof.No company lives with the tenant 24 7.. and being that your investment security is 100% dependant on what that tenant does..

Can I find a deal that will payoff my debts and secure a good future? 

Considering then that you probably don't have an social security number and no bank account in your personal name it's going to be even harder.

I currently hold their security deposit, only $500 and technically I have threatened to report their business to code enforcement before (I held off) but I could use that as a negotiating tactic for leaving on time, since the fines are up to $5000 in Miami and it’s possible this tenant Does not have full citizenship status.
