If you have absolutely no use for your cash don't waste your time and efforts investing in real estate.

There are also many breeds with above average aggressive tendencies, so regardless of the owners best efforts, the wild cannot be taken out of them. 

Passive income suggests (at least to me) that no effort or time is required.

I was on Dave Ramsey for years and had my emergency fund and my wife and I threw all of your effort in paying off our house which we successfully accomplished several years ago.

Probably with some research and effort.

Don't get "stuck" doing it all yourself or with your spouse. ( Get to the end of the post to read why).I'm still buying (and selling) but I have put more time and effort into repositioning my debt by lowering it (giving up some cash flow) and refinancing  for better terms but fixed for as long as possible.

My point was that if you intend to create massive wealth and do so with out the difficult efforts of finding 100+ individual doors, and also do so from a passive or semi passive standpoint, then multifamily would be the best choice in my opinion (or something similar like other commercial class buildings).Thanks for your comments David, I think we are the on the same page and your last comment allowed me to respond with more details.

Well worth the effort and well worth the risk in my opinion.  

IMO, Y O U don't build a path - - you follow it.I applaud your effort to get off the 9-5 treadmill; really I do, as I ran like all heck for 37 years on it.IMO, the wholesale PATH has lots of time, effort, labor and even more RISK than Sub2 and ATID. 

the money and effort to develop the residential units is great, but the potential reward can justify the cost and effort.
