I live just west of Portland, and I'm looking to get into REI a little more to supplement my retirement as I'm self-employed (General Contractor) and don't have much of a traditional 401k, etc.I started out buying a duplex as my first house back in 2005, which I lived in one side for 7 years and rented out the other.  

Also I don't like the fact that the association can do special assessments that will impact my cash flow.

I am a banker by profession, and am looking at real estate to supplement my income and eventually turn it into a family business.Thanks!
