Should I be looking at this as a goal to keep buying rental properties to build up my portfolio?

I have an idea of what I want to do to get started but have a lot of questions and would love to pick someones brain about investing in NJ.I would like to get started by house hacking for a year or so and build up some equity and save some cash for another after that.  

Maybe in the 500k - 1M range and build up a track record of producing results and profits.

Don’t let this mess build up over time.  

Less infrastructure buildup, high turnover compared to conventional office but much less work than events etc. 

Get a website, and use that money to build up your site.

Sometimes the eviction goes bad because the buyer/tenant answers the complaint and shows up with badly executed CFD agreements.Looking forward what others in KS have to say about CFD foreclosure.

You can build up good cash flow and equity.

Almost nothing penciled out and I wasn't interested in buying properties with negative cash or banking on the possibility of future appreciation.So I resisted buying bad deals and pretty much sat on the sidelines from 2005 to 2009 and continued to build up cash, contacts, my credit score, and my RE knowledge/education. 

(So you don't help to build up the rest of our medical bills through the medical system of course.)
