You asked for reasons why someone might choose to move out of their house for 6 months or longer rather than rent it out. I gave a few; nothing more. By all means, I support the local government's right to pass whatever laws/policies/incentives they want as representatives of the residents and a policy could be good on balance even if it screws over a few edge cases.

BTW, most of our overseas assignments are 2 years initially. 3 months seems more like a long business trip, not an overseas assignment to me.

You must be filthy rich to be able to keep an empty house for 2 years.

Not if your housing is covered overseas as part of the package (whether private or military).
