I would not waive it, as that is not helping them shape their behavior (paying rent on time).As an aside, as others have said - $300 seems awfully high.  

It's not good to reward the wrong behavior.

Worse in my view is that the current PM contracts actually encourage bad PM behavior by rewarding putting weak renters in your property and when they leave or have to be evicted the PM gets rewarded with yet another months rent by placing another weak renter in your property.

Civil rights lawyers or fair housing groups will often take cases in borderline situations like this assuming that they will be able to find more evidence of bad behavior as the case goes on.Edit: craigslist probably flagged no pets as they have a dog/cat button on the post that you check or not.

After watching the video, my thoughts were to ask the lower neighbor to move as that type of behavior is not acceptable to us, however, my experience is strictly with single family homes and we never had to deal with such issues.

They should be directing this behavior as unacceptable and the police should have been called.  

Small ones ( 10 units or fewer) are notorious for infighting, mutually destructive behavior, petty grievances, illegal maneuvering, etc.I have had investment experience in all types of condos.  

Remember, a good rule of thumb is: "The best predictor of future behaviors is past behavior".  

The Board tends to be focused primarily on the fiscal management of the complex and not (in my experience) as concerned with the behavior of individual tenants.  

Fortunately, as a Florida Mortgage Broker, I'm not under FRIC, FRAC or FRECAlso, Mortgage Brokers don't go around filing ridiculous and petty complaints on each other at the drop of a dime.So unless there's something I don't know about,  Florida Mortgage Brokers are pretty much free to circumvent Realtors and go straight to the seller anytime we feel necessary.So often sellers are completely oblivious to the nonsense and unprofessional behavior of the listing agent they've chosen.Of course, I don't want to get the buyer's agent in trouble, so I think it's best I take the initiative and circumvent the listing agent and go straight to the seller to get the sales contract extension.
