Do managers that advertise 8% only do 8% when there's a bundle of doors to manage?

Do you think purchasing a property in Philadelphia, PA, and managing it remotely from Westchester, NY (Roughly 2-2.5 hours away) with the help of a local handyman would be too much of a stretch?

Hi all,I'm looking for recommendations for a property manager for my 8-unit apartment building in Cullman, AL.

Out of the 300 properties I manage, we only had 1 eviction last year.

Making sure we can manage our own properties in these areas.  

Apparently, the person I am under contract with was managing the estate of the actual owner who recently died.  

It also includes managing your existing investment well to ensure you aren't bleeding money due to bad tenants, excess maintenance, etc. 

Build a strong team with experienced lenders, real estate agents, and property managers, and educate yourself through books and podcasts.

Any realtors / property managers / contractors / wholesalers please connect with me!

I manage many of them in Jacksonville, and have a lot of information on them.
