We had our attorney appointed to become the executor for the probate, then completed the redemption through the probate court.

As such, they offer no incentive for a tenant's lawyer to sue me since the banks would get first dibs on anything if the courts forced me to sell.

I put $0 in the 5 day notice for both court costs and legal fees. 

The flip-side is I don't want the toilet overflowing, costing me tens of thousands of dollars of damage only to have the tenant tell me in court that I specified that I didn't want him calling me in case of a clogged toilet immediately but trying to plunge it himself, and that the plunger broke so he decided to do nothing.

Also, we had letters from our HOA stating that this was our 3rd and final notice before they took us to court because our satellite dish was too far forward and grass was too long...apparently they didn't care that we had just moved in when we received the final notice.

Likely will have to go through the normal red tape and take them to court.

If he is serious, he can try to take you to court.

I’m not an attorney but I would think if this “new zoning” affects the resale value of your home (rental or otherwise) you have a pretty good case in court. 

Can you get a court order to sale (partition) if you cannot locate the heirs of an estate?

Repairs, improvements, legal/court fees, travel, etc.You don't "write off" the mortgage itself, but you can on the interest.
