I have 7 doors, and I wanted to get some ideas on a better way to screen for tenants.

This is a much better deal then on income, especially if you area self employed. 

Something I learned early on is, "there's always a better deal out there."

Are there better ways to make money right now besides real estate that you have experience in?

I think it's good for owner's to be a little bit hands on in the management until they build the right systems and process to be more passive, or better yet hire an internal manager yourself once your portfolio gets to the right size.  

Kicking myself for not growing our portfolio sooner but better late than never I guess.Here's the thing - We don't live in the US, my husband is a US citizen but since he hasn't lived in the US for many years he has no credit history.Now comes the fun part - we are in a lot of debt where we live (like $115k in loans).

Is this a good idea I should continue pursuing or are there better options? 

Lease Options: This is better than a typical lease because there is an expectation that they will buy and in many cases, you can make the tenant responsible for some of the maintenance and also you get some option money.3.

@Sean LemonYou are 1000x better off investing passively then paying a huge fee for someone to find you deals.

Starting with an Out Of State MTR / LTR strategy is smart, especially targeting travel nurses or university students.Focus on areas in Texas or Indiana with strong job markets and growing populations for better rental demand and investment potential.
