You may want to wait a while longer and keep stocking up on things.
If you think it would be safe leaving it on your 5 acres, I would suggest you consider getting an electric generator and large fuel tank, and begin prepping the site before you move there.
It's your decision, but in my opinion, the longer you wait, stock up and prepare for the move, the better you'll be.
And if you plan to start growing your own food supply, you'll need to prep the land well. Clearing, cutting, removing sod, rocks, etc., plowing, and all the other work related.
Also, you'll either need a well with a hand pump, or a fresh water stream.
