By the time the customer figures out the local process and who he buddies up to and locates and screens subs etc , there is NO cost savings . 

@Max McNamara please do due diligence and screen:)  I do not invest in DFW   was just helping you out

Plus, tenant screening may be even more important that the state's eviction laws, since the goal is to get the right tenants in the property in the first place so that you have to evict as infrequently as possible.

So, the first question they usually ask a PMC is about fees - instead of asking about services and HOW those services are executed.EXAMPLE: PMC states they will handle tenant screening – what does that specifically mean?

Again, there are good ones out there but you need to know what a good one looks like, then you need to screen them until you find one.Remember: cheaper doesn't mean you'll make more money.Start by going to www.narpm.org to search their directory of managers.

Assuming i find a property management team that can be trusted, and that the tenant is properly screened, how could something like this go wrong?  

While Section 8 offers benefits like guaranteed rental income and a larger pool of prospective tenants, there are administrative requirements and potential differences in payment expectations to navigate.Before making a decision, conduct thorough tenant screenings to ensure tenants meet your rental criteria beyond their Section 8 status.

I may have been listening to the podcasts too much (I'm through around half of them)I'm all for giving the current tenants a chance, but it seems like I have to just take them without knowing anything about them, no idea of how they were screened, their payment history, etc.This is just a duplex, is it a very common thing to sell an occupied unit (on the lower range, not 4plex+)?

I self manage my like 5 property portfolio. follow this link and see my pre-qual. https://form.jotform.com/221952639521155Thanks for the tip on building own prequal screening.   

I have a lot more confidence when I screen for tenants.
