Buying a property management company

[Josh Bakhshi]

I got notice from one of my property managers that they want to close shop.  That would put me in a hard situation.  I have a few properties there and no other property management companies to take over my properties.  I got into discussions with the manager and he asked if I would partner with him.  My experiences with managers are only as a customer.  Does anyone have suggestions on what I should look for to decide to be partners or not?
