With vacant land the risk is low, they might cut down some trees or pile up a bunch of trash, but it's pretty hard to get the land totally destroyed... 

house would have to be destroyed with a high likelihood in the next 10-20 years for that equation to make sense for me.

The bank will have nothing of value to collect in some cases except a home that is destroyed.

Think about it, those are the 2 things that can absolutely destroy your home (flood or fire)   it's worth doing it before a problem occurs!

Payroll taxes seem like that would destroy cash flow as soon as the company got very big.

No reason you should limit yourself to totally destroyed houses.

No one intentionally destroyed the property but all of them left the property in poor condition but only required minimal repairs.

I had the property for 7 years and I had to evict tenants who destroyed the house.

With carpet...I shampoo and steam clean it time after time after time...then when you think its destroyed...I dye it for $150...looks new....then the cycle starts over again...shampoo and steam cleaning at each turnover....finally after it has been reduced to basically indoor/outdoor carpet thickness....I replace it with the cheapest carpet I can possibly find...usually about .69 cents labor and materials.

I'd also say you're in the right to charge for damages incurred due to the dog destroying the carpet.
