You poor dear,
Don't you have an agent to help you?
If you are in Huntington Beach and you do not have an agent, give me a call, I will try to help you.
(The listing says, Huntington Beach, but then underneath it says, you are in 92071.)
Here is how I would handle it, I would draw up a release of deposit, and give it to the buyer, asking them to agree to damages should their legal action which will take months does not go through.
I would maybe ask the buyer to pay your space rent, while they are messing around with it.
