As an example, our contractor noted a leak in a faucet and said, "That's $200 a month going down the drain right there, guaranteed." 3) One unit with a long-term tenant with dogs smelled like a urinal except 50x worse.

What can/will come up here is that day when you and 2 other agents, within 45 minutes of each other, call the same assistant with something super urgent that must be done right now.

That is like giving your dog a T bone steak after it craps on the carpet .

We had an lady and her daughter scheduled to do the move in walk through and receive the keys  and is now asking to break the lease because her dog was hit by a car today and can no longer walk up the stairs to the residence.

The tub is great to wash dogs in etc. 

I've also charged 15% on low value mobile homes or land, owners want me there each showing, want 48 hours notice to move dogs, priced higher than worth, back of park so no visability, they want to question every word of my description and choose what pictures go in what order.

Is it worth going through the advertising/tenant swap out just to avoid our otherwise ideal tenants having a dog?

On a personal note, I am a dog owner and my dog provides emotional support to the entire family.

I have been able to avoid trouble tenants in the past through the normal mechanisms, but had my first real problem guest this week.I'll save you the gory details, but essentially the tenant showed up with a dog, lied about taking it to a pet hotel, and kept it in the unit while they were inside. 

I’ve heard these dogs to be sort of protective, of their families, & territory.
