We are trying to build a portfolio in western PA where we currently live. 

My goal in the long term is build up enough equity/extra income to retire at 50.

Steve, the question should be more along the lines of whether you want to build a retirement fund vs try to bring in passive income now.

Hello, I'm a self-managing landlord and I'm looking to build a network of go-to people for maintenance and emergencies.

I chose to build my PM business from ground.To create a working system and to organize processes is difficult in the beginning, but to my experience it is possible to create a working model based on personal knowledges and then to provide a high level of service to the clients.

You are betting on them to build the condos to the standard they are promising you!
