Becoming a priority to a property manager

[Brie Schmidt]

I was talking with another investor about buying out of state.  I said that I don't think someone should do it on their own unless they can scale quickly, therefore becoming a priority to the property manager. 

Then he asked how many units or how much gross rent would make you a priority.... and I wasn't sure.  To me 20 units or $10k in gross rents would be a priority, but maybe I am wrong.  Any PM's out there willing to share?  What do you guys think is the tipping point with a PM?
