Move when you can.
If you wait for moving when you must, lots of others must move too, and it creates a disaster as far as finding a place, finances, logistics of getting household goods moved, finding a new job, doctor, etc.
Yup. Don’t wait for the enemy to design your strategy. All they offer you is defeat or surrender.
Moving is hard enough without having to deal with limited options.
The only truly good time to move is the one you see in hindsight and you can’t go there.
