So as a practical matter, the school district bring these actions to collect money from the owner or a lender.

@Andrea NielsonI've never had to do this in practice, but I do believe that if they share a living space you can specify.

May as well not bother screening at all with that practice.

Would be helpful if you share your experience and the best practices. 

I think practically, it would be better that I would focus on wholesaling, though I understand it would be very difficult to find the deals.

I suggest using a lease that is as one-sided in favor of the landlord as the local landlord tenant laws will allow.Most agents aren't specifically trained in how to screen tenants, quite to the contrary of the beliefs held by many uninformed people who believe that agents know everything about real estate because they are agents.And I have posted about this previously on BP; a search of the BP forums would have found at least one of these other threads.https://www.biggerpockets.com/forums/52/topics/829...https://www.biggerpockets.com/forums/52/topics/156...https://www.biggerpockets.com/forums/12/topics/177...https://www.biggerpockets.com/forums/52/topics/215...If you have to or choose to rely upon others to perform tenant selection for your rentals, then you should at least learn about how to do this, so that you can determine whether the person you hire has an understanding of what to do, and to be certain yourself that the person hired is actually following the best practices (and not just reciting them to you just to get hired).You should be able to give a profile for the sort of tenants you wish to have occupy your rental, so that you can create some specific qualifying criteria.

For example, studies have shown that landlords in low-incomeneighborhoods overcharge housing voucher holders,making the program lesscost-effective and therefore limiting its reach (Desmond and Perkins 2016).Public policies aimed at easing families’ rent burdens should be grounded ina firm understanding of property owners’ business practices.4.

Expect a 2yr learning curve because there is a ton to learn, practice and master, it does not happen over night.

But again, this is a standard business practice.
