They should fix the gate for you if they broke it.
Both my bestie and my microwaves died at the same time. We didn't know it and we both ended up getting the same kind at Walmart for 90 bucks. We love them! (Hamilton beach)
You could maybe just start checking out real estate prices there just to test the waters. You wouldn't have to move right away.
((((hugs)))) and a prayer for wisdom. I am so sorry about you gate, a basement.
