@John D. and @John Underwood, the reason I am concerned about the difference is that I'm trying to optimize my pricing.

"Invest as if you have no money and invest as if the market will crash tomorrow"I forgot who or where i read or listen to this but i am pretty much optimizing my portfolio base on the above and ask this very question on every single investment purchase now. and Yes, according to Grant, Robert Kiyosaki, Petter Shiff, Trump, etc...there real crash is just around the corner. the 2008 one is just a baby one.I believe them. and prepare every single minute now.

While clearly you can do it yourself (setup, design, lead pages and generation, search engine optimization, auto-email response), this is a lot of work.

Another thing to keep in mind is there are more optimal properties to maximize rent per price paid.

Maybe this is 3-4 revenue increases and expense optimizations  thats gets me $10K more a year just doing what I'm doing, we shall know in about 18 months though.

I know some pretty talented land investors who also have the ability to deploy their own farming operations to get value out of tillable acres, and as a newly minted real estate agent in IL, I'm hoping to invest along with them on the next couple of pieces.We also have a system to optimize and better position land to extract maximum value. 

I'd say it's a cautious optimism with a deal that I think is good enough to use retirement funds on.

To conclude, a sale leaseback can be an optimal solution for both a business owner and commercial real estate investor.
