Don't rely on him paying and if he doesn't pay you, send the payment in anyway and try and collect from him.

I just purchased a 23 unit property and I'm looking for an automated way to collect rent. 

You just collect monthly payments.

Honestly, we just want them out (I know we're never going to collect - I just want to stop the bleeding), to clean up the property and sell it.   

I would classify those as two different approaches.Do you want to learn the ropes, while collecting a paycheck, i.e. working for? 

I see a lot of folks talking about services that can collect the application fee AND do the screening, such as cozy.co.

Buying a house and being in collections means you are putting your new house at risk, so I wouldn't do it. 

Landlord: Focus on applicant criteria, vetting potential tenants, thorough lease agreements, outline tenant expectations, perform regular walk throughs with tenants, and use web-based rent collection and maintenance requests. 

In essence this sounds like you are saying that the mortgage still exists as a lien again the title, however, the recourse the lender has is now limited to just seizure of the property, and not trying to chase collections from the FIL.

@ Dave Fosteractually, I only put the kids on recently and we haven't been collecting rent for a while because the house was thrashed and the friends that moved in were "supposed" to be fixing it up.
