Distance between well, expansion tank, and house?

[WilliamWWhitworth]

Needing advice on how far away from the house can I move my expansion tank and it still be as effective as it is.
A little background, my well is actually about 4-500 feet away from the current location of the tank, which is about 50 feet from the house.
Would I be ok moving the expansion tank about 200 feet closer to the well and away from the house?

Attached is a photo of the property. The blue is the current location of the tank, the red is where I want to move it to, and the green is where the well is located. The red spot is an old well location that the power to the current well actually runs to (it's actually where the start capacitor is located).

As long as there are no check valves in the system except for the one on the pump, the pressure tank can be pretty much anywhere you want to put it. HOWEVER. the pressure switch must always be very close to the tank.
