I've already invested in a duplex in NJ (I'm renting it to two families and managing it) and a single family in MI (living in it).

I use Ziprent property management to find new tenants.

Take a look at some trade accounts and a line at the Big Blue and Big Orange if you are going to self manage.  

You're looking for increased cash flow, so managing more doors and/or strategically utilizing leverage can make a certain sense there...but as you mention financing costs aren't as rosy as they were 2-3 years ago. 

Does anyone have a recommendation for a property manager?

How many units or homes are you managing?

New investor here looking to build my network out with property managers in the area.

I'm structured and want to pursue something in real estate or money management.

They may feel a sense of entitlement, and they may not even be good renters.Unless this is some unique situation like a ranch that requires special skills to maintain the property, I recommend you remove the caretaker, spruce the place up, and put it on the market at market rates.I also recommend you look for a professional property manager that can help you navigate this immediately.

There are privately managed motels that do "ok" but their rates are DIRT CHEAP to be able to compete and their occupancy isn't even close.
