Plus, you get huge appreciation here based on how many companies are moving and developing here! 

Good question, they seem to be all over the place depending on the area and I am not an insurance specialist, I think typically 1.5-2x normal rates but I could be off by a bit i have been honing in on White Hawk if you know that development and its in the pines but it does have water system with hydrants but volunteer fire department ..

I personally like to buy in towns/neighborhoods in which no new builds are possible within 10 miles because all the land is developed.

There is so much growth here - population growth, job growth, and companies moving and developing here.

Much like by the end of this decade, I will take those same steps to become even less involved with work and have more times with my kids who will be really developing and that will be my focus.The difference once I made money, and was able to make it make money for me I de-risked by eliminating leverage.

If you don't have the funds yourself, you need to develop a solid relationship with those that do.

Thats a lot of work that a company would have to do and they would want their money back on the development costs.

Plus macroeconomics here in Columbus is booming right now because of developments from Intel, Meta, Amazon, Honda, and lots of major companies building out here.

Does anyone know, or have a good idea, about the difference in returns on entitling & developing the land for each scenario, with final objective to sell to a builder to build and sell the structures him/herself.  

I ran your numbers through my own development proforma analyzer and it looks really good as a DSCR loan.
