You will need a software, screening policy, work order request system, etc... 

My final counterpoint:Dynamic Contact Share with Fireworks Screen

I would add that screening tenants and shorter leases (2-4 months) is the solution to mitigate the risk of being stuck with a problem roommate-tenant. 

And I have tenants that make multiple small payments every month because after they’ve moved in they’ve had their finances screwed up from what they were when I screened them.

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?

The frameworks others have presented of viewing the site as a lead-generation tool where you, as the host, are handling all the payment processing and screening is pretty accurate. 

What exactly is their, "strict tenant screening & matching process"?

As a rental strategy for non owner occupants, it absolutely is a fantastic way to generate the highest return, that's true.....but also, and most importantly, your screening has to be on point, and without that, it won't be as effective because one bad roommate can ruin the environment for the other roommate tenants. 

Challenge is where is their motivation to properly screen applicants and get rid of nonpayers?
