It's exciting to see how many helpful people are involved in the industry and suggests to me a lot of potential for networking and symbiotic relationships.

It is truly unique, offers excellent ROI and the starting investment is just $10k: Have I Found the Holy Grail of Passive Real Estate Investing?

I suggest reading the guides and browsing the forums.

There are a lot of benefits of being a member which I highly suggest.

An Irish couple in their 60s investing just to take nice vacations and earn an extra $3K/mo.Point is, the 50-100 goal is certainly achievable from where you're starting, but you'll need to be aggressive depending on your timeline to reach that many units if you go one by one.I highly suggest one by one instead of buying an existing portfolio unless you can really learn all about the portfolio and avoid overpaying for it.  

So much of the education and experience in construction management translate to real estate, so you are in a great position.My suggest for you is to look into "househacking."

Excellent choice -- both of profession and community.
