I always engage qualified legal and accounting professionals prior to transacting in new spaces or employing new strategies.

Of course, this assumes you're keeping track of everything religiously, as it would be hard to reconcile such records and ensure completeness.Otherwise, look into hiring a bookkeeper/accountant/CPA who can provide this as a service for you and can help advise you proactively, so you can prevent issues rather than remedying them after the fact.

Never had an issue in the past with a tenant of 10+ years but they recently moved out and we are trying to figure out the best way to add something in the lease just in case someone goes nuts with utilities(tries mining crypto or something that would run up the bill a crazy amount).

Were there any unexpected issues? 

We thought about hiring a lawyer but the legal fees were expected to be in the range of $10k to $15k and would have taken months (if not years).

This may include the right to foreclose on the property and take it back through a legal process.

Quote from @William Sharp: The only way to legally claim the property is through a tax auction or foreclosure (if he had a mortgage).

If it's an issue of paperwork, fix it and you'll be paid.

@Moses Moreno Depends upon who you talk to and which side of the issue they are on.

There’s a considerable amount of traffic and disturbance at times during the day but once evening comes it isn’t an issue. 90% of the people that use the parking lot respect my two parking spaces and don’t park in front of my house.
