If you see any holes in coverage or other followup items, please comment.

For the truly ambitious, the right site could then be further developed (outsourced) as a "green cemetery," which I refer to as "selling $500 post holes" at a few thousand per acre.

This is just my opinion and most likely wrong, but the US and its printing of money put themselves in this hole where now their debt is expensive to service which is why rates are high.

A hole or two (check how many you need.) and some plastic pipe?

This will happen in a market with balanced supply and demand, in a monetary system like the US, with fiat currency targeting 2% inflation.- In some markets, that are growing quickly, with great jobs and lots of inbound migration, this could be a little higher - like 4-5% per year over long time periods as demand outpaces supply.

And following this convoluted rabbit hole calculate what kind of property you would need to exceed the profit level you have right now. 

This section of the guide helps me to better understand how you can use the www.mysmartmove.com in conjunction with other forms of background checking:The Tenant Credit Report: The tenant credit report will contain a wealth of information related to the tenants credit history, including a detailed list of all the tenant’s open or closed credit cards, car payments, monetary judgements, late payments, and more.

Also I would talk with those that install systems they usually have a good feel for areas and maybe will do an onsite inspection.for me if just vacant land and all i need to do is dig a 3 foot hole to get soil samples I am going to just do that. 

Take the toilet out without damaging it, put a sanitary cover over waste hole, put toilet on shower floor.

US prime-age employment-too-populace ratio is 80.9%....I should have never looked down this rabbit hole, it's depressing, lol.
