In those cases just follow the law.My fear in pushing it too far is the $20,000 it can cost to just show up in court with a lawyer and fight a single issue. 

I fear that many sub to transactions take place with the seller being unsophisticated homeowners who have no earthly idea of the risks involved and potential devastating consequences that can occur.

I call it the Winter Fear. 

At first, I feared going to court, IDK why, just did, the idea of "court" just seemed intimidating. 

That fear leads landlords to make the mistake of:a.

The other aspect I feel is a byproduct of inflation and/or a fear of a downturn in the economy.

I did not want to move or sell anytime soon but fear that this option has been taken away from me.

Keep communication open and they may come around after they get over the fear.

To assuage their fears I hired a contractor to do the removal.

So no fear on the end side if you decide to try this out.
