Seems residential home pre-sale inspections cannot be run for theA/C side if the outside air temp is below 60F

The most inexpensive residential AC systems lack a factory
installed head pressure control which is why it's not prudent
to run them in cold weather.
Why couldn't a thermostat that can sense condenser coil temperature
be used to turn on the fan when the coils reach some pre-determined
temperature?
That's exactly what the fan speed modulators do in the links I
provided. The ICM manufactured controls I use, come with a
temperature sensor that's attached to the high pressure line
on the condenser coil to operate the control.
You kept mentioning "head pressure control" which I interpreted as some
sort of pressure-sensor (sensing line pressure) as a way to operate the
fan.
