The domino effect will eat your equity as well as life savings.Unload the properties while you think it is the peak price. 

If the landlord is responsible, there may be a way you can seek damages as that's putting you and your family in danger.

It it's actually touching your building and could potentially cause damage, the other owner should pay for it but I don't know if you can actually force them to do it.Call your City and ask for guidance.

The tenant leaves, the property is damaged, who knows.

However, you are a landlord, your only concern should be if they pay their rent on time, keep your place clean with no damages and are not doing any criminal activity in your property. 

I showed @David Krulacvia PM  a property that underwent what I will nickname "the trifecta" - it had been sold by the TCB, then the mortgage foreclosed (on the buyer at TCB), then the school district had the property sold at sheriff sale to cover unpaid school taxes (the lender's lien was no longer in effect because of the mortgage foreclosure sheriff sale, and lender did not cover the school taxes to prevent that sale).

And maybe less potential damage. 

I purchased this new construction home about 8 years ago it under a “go zone” program which provided significantly can’t tax benefits for building new homes and renting them in areas effected by hurricane Katrina.

Broken windows are usually the owner’s responsibility unless you can prove the tenant caused the damage.

Bottom line- you need to find out what damages you may be entitled to in regard to undisclosed information.
