The same two acres, could probably get about 30% more if it was a rectangle versus a square, due to less turnarounds.Attachment:This is a relaxed layout, I did not try to cram the spaces in.Rows and Road ConfigurationARoadBCRoadDERoadFThis layout is on a 2 acre square.Roads are all the same width.All rows are set at 45 degree anglesUnitDescriptionRow: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 notes:If I didn't do back to back would have about 30% less spots ( you have to add more driveways for the same number of units) and payback would be around 18 years versus 12.

and will my first purchase effect my borrowing muscles?

Often by the time we muscle thru all the paper work the deal falls apart.

Once you're in the home, live in it for a few months before starting, to get a feel for the flow of the house.Keep your sanity (it can be tough living in the middle of a giant mess) by keeping at least one room completely untouched, so you can have a place to relax.

Any backyard/deck pics you could snap to show where they can relax and enjoy their morning coffee/tea outside?

Need to calm down and relax because wow.

You might think of taking a jog outside and, as you relax from the exercise, practice in your mind what you will say when you call these people.  

Relax and be yourself.
