I certainly don't want to give up on the Netherlands after some proper search for possible investment in the Netherlands. 

That is one of the first steps: Have the proper mindset.

That could be true if it was proven that the lawn mower was faulty / not maintained properly. 

If they are forced to relist the property, they need to advertise it properly.

As long as the proper forms are filed/ recorded, agency is disclosed, and no one feels some shadyness is going around, you are good.2.

check your local laws on how to properly determine if a property has been abandoned by a tenant before you clear it out.  

My question is I have a tenant that was given proper notice (120 days) that her was expiring at the end of June 2021; if she wished to renew her lease, there will be a rent increase ($50).The tenant responded and asked if she could have until the end May 2021 to give us her decision.

It sounds like the property may need to go through probate to get the title properly in your name.

My guess is that the two lollies were not leveled properly, and the weight of the 2nd floor shifted, causing increased pressure on other joists and a new set of problems over time. 

How do you transfer the leases properly?
