What is interesting to me is that as of May 28, there are 618 SFR homes for sale in Area 21 on the FMLS map, which includes Buckhead & Sandy Springs inside the perimeter. 

What does the Water supplier require to attach to their system.If water or soil ph does not affect copper it is the best and obviously most tested for durability and longevity in the interior or exterior.  

Hi Sandy, I would check out OBIE or Steadily.

It is also possible that blue acres buyouts can take place in certain areas but my experience on this is with Sandy.

@Brad SandI forgot to mention an example of trading a marginally performing and less desirable property for a better potential.

Off the top of my head, I would want to know about zoning, dividable, legal access, physical access, road agreements, easements, floodplains, utility access, wells, well agreements, setbacks, environmental issues, and soil tests.

In cold climates you want to make sure the deepened perimeter of the slab is below the frost line so the expansion of frozen soil doesn't heave the building up, but if it has been fine since the 50's you should be ok.

If it's near water, are there problems with flooding, soil erosion, insects, etc.? 

This type of movement indicates wall is being pushedin by soil pressure.

Inspecting everything, making sure things work, testing soil, etc.On the face of it, seems like an OK deal.
