I’m interested in feedback about this as well as any ethical or legal concerns it could create. 1.

The concern being that they signed the lease under the premise that they would have use of the entire acre (which they don't use).  

Retail is an even bigger concern. 

This post is about my #1 concern, which is as follows.I have a fairly substantial amount of restitution to pay from a judgment on me personally.

After discussing my concerns around the current market conditions sorrounding COVID-19 with my agent, she mentioned if I were to cancel the agreement and terminate the contract that in addition to losing my earnest deposit, I would also be liable for buyer and seller broker commissions. 

Not trying to be political, but as far as I'm concerned, there are too many uncertainties and no real convincing plan/road map.

This was offered as a thank you, and to help with some stagnate water that does buildup in my yard.I'm concerned about liability.

If so, I would say you have bigger concerns than where to park your savings, and would instead focus on banking as much money as possible. 

If that's still not a concern then go for it. 

There aren't many of these in the market today, which means bond buyers shouldn't have the same cause for concern.
