Have you had experiences where people under delivered?

Cost me 200 K is taxes because I could not complete the 1031 exchange.they talk a good talk BUT DOT NOT DELIVER.

Despite having delivered over 480 investment properties, we always seek the opinion of a property manager for each property before considering it.

We will purchase 20 1 trip 20-foot cargo containers for $3,200 each set-in place and delivered. 

I know this statement isn't regarding Maryland, but in Florida, the landlord must deliver written notice of intent to claim monies from the deposit by certified mail to the tenant's last known address within 30 days from the vacate date upon termination of the lease.

Delivered a 3-day notice to pay rent or quit 3 days ago.

Ohio seems to be the best state I see that is delivering better results.  

Personally I require they give the money to the title company and it is refundable in the event I cannot deliver clear title.Hope this clears it up for you!

So, DELIVER on EXPERIENCES.     

I don't know what your state's statutory or case law states about the lease provision you mentioned, but assuming it's a valid lease provision, you could give notice of lease termination based on that provision, but be careful, because if you deliver a notice to pay in conjunction with a notice to terminate, a court your jurisdiction could rule that the 2 notices are "confusing" and could constitute a defense for the tenant.
