You also need to have a great property manager who does really good screening.

I am not a marriage councilor, a quick cash business, bank, humane society etc etc.I say all this to make the point------- Have a lease    Stick to it       Be firm     Don't make concessions     It's an agreement/contract       Hold them accountable     They are an adult      Don't accept a reduced rent because you feel bad for them - this is a business not a charity.Because you accepted some sort of payment of rent you may not be able to count this month as violating the lease on the rent amount - you will have to check state and local laws.On the pet provision that was broken, you should be able to give them a 30 day vacate notice for violating the lease agreement.

Don't buy war zone properties and pre-screen over the phone correctly. 

The system is broken, let's progress towards fixing it.The predictable opposition to the Bill is from the Community Association Institute (CAI) and HOA trial lawyers.

Income and credit are my initial screens.  3x and score 600+.  

Are there any red flags to watch out for when screening?

However, that would have broken the 'arms length' relationship that must be maintained for the SD-IRA LLC (checkbook style). 

We like - good communication, great tenant screening, clear financial statementsWe hate - padding expense costs

I can't give you any advice on becoming an agent but you can use the search box at the top right of the screen to find some other posts that might discuss the subject.Good luck!
