Some parcels are actually worth as much or more after the credits are clipped as before. 

We were not able to recover any yard damages due to other damages they had left that needed repair, which empted out their security deposit.

No social or credit pull needed upfront. 

After they book, it's still a good idea to use the platform app for communication because then the platform has a record of what you and the guest have said, in case you need it when a guest does damage and admits it to you, but later denies it to the platform.  

And when you said the management company takes a 550 credit score , all I see in your future are evictions .   

Aircover is a mild form of property damage insurance where they MAY cover a guest's damage at their discretion, and you will have to fight for it. 

If any damage arises from her negligence she will be getting the bills for damages, plus costs of collecting which you bill as well as your attorney in addition to the termination of her lease.

Now, I'm imaging a scenario when every one of these tenants move out that I'll be paying their entire security deposit + interest even if there are damages beyond normal wear and tear. 

The Landlord will verify that the rental is empty of all personal belongings and trash and that there is no damage beyond ordinary wear and tear. 

Ask an attorney for the cost breakdown, factor in holding costs, assume they'll do more damage on the way out and then ask for a bit more for the headache.But again, especially with no experience with evictions and it sounding like a mess, I would be very tempted to just walk if the tenant is not going to cooperate.
