You should check out AZREIA (Arizona Real Estate Investors Association)!

Haven't checked.

That game ends one way: fines and Saturdays spent calling plumbers who don’t answer.Here’s how I run it now.30 min unit check (quarterly): Do NOT wait for tenants to report problems. 

Notified the tenants to come check and help secure the doors.

Do you still background check the tenant? 

I would rather check in to a project manager to make sure things are being completed on a timely manner.

Check FB.

The unit checks all the boxes, including a good price, except very high amount of Radon.

If you are interviewing property managers, before checking on all these tangibles, I would suggest to check,Experience & Portfolio Fit: Ask what types of properties they manage and how many units they handle.

Will I need to do a background check on another platform?
