You have to find the right one by asking the right questions and getting references.  

Still in the beginning stages, but will refer back as we move along.

Recommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

Are you referring to a community of LP investors on BP or somewhere else like Facebook groups ? 

For reference I am in the northeast.

Only took 30 seconds to find this website, how much effort are you putting into this?
