You can sell with owner financing and increase your profits that way.3.True, it’s not completely passive, you do have to send out mail and do some research and communicate with buyers and sellers.Probably not as much work as flipping houses though.4.Competition – yes, but much less than in SFR.I get tons of postcards from people trying to buy my rentals.So far no one has told me they have other offers on their land5.Risk- yes, but you can start with small properties until you are more comfortable and experienced.On my first mailing I limited the mail to properties under 13k in value.6.High Volume – you can or you could do fewer high dollar deals its up to you7.No Tax benefits – you are right this is flipping not investing.The same can be said for flipping houses or wholesaling.8.I don’t have any idea if this is the best model……Actually for me the best income model would be to have enough money to put it all in a index or REIT fund and just live off the dividends.There's nothing magical about it. 

@Victor S. tax advantaged dividend yields on major market index funds are still better than short term interest rate vehicles.

I have my SD house and significant index fund portfolio that should provide long-term wealth building.

BP doesn't have all states covered yet, but they covered all the big markets first. http://get.biggerpockets.com/forms/index/

Then I would rather invest in Index stocks as there will be less maintenance fee, if you are going to manage yourself, put in additional money to cover money expense, and pull out more money for additional repairs.Just something to think about, hopefully the suggestion helps.Daniel

So for instance, my rent payments go directly into an account where the funds are automatically deposited into high-yielding index funds.

It's a myth outthere that accredited-investment program can outpace residential RE/ or index fund like S&P500.
