I allow dogs in all my apartments but of course not the breeds excluded by my insurance.

When I first started I still posted DEALS around the net, but quickly or not so quickly learned to stop that behavior.

Assuming they, their 3 cats, 1 large dog, and bunny all move out and keep the place in good condition.

ulta high risk.. if you want to do this to increase your deal volume just do it yourself and pay the bird dogs a fee to bring it and manage it if that's what they are doing..

If you call a tail a leg, how many legs does a dog have?

If he weren't an agent but a bird dog and came to you with this deal offering a 60/40 you or 70/30 you profit split would you still say no?

He chained his dogs in my properties back and front yard. 

We as a community tend to let things go because it "isn't worth the hassle" but this attitude is often responsible for the continuation of this kind of behavior and you would be providing a valuable community service. 

Hopefully they have cars and phones and clothes they can't afford like normal renters and will correct their consumeristic behavior, allowing them to qualify within 24 months.

But I've had to start learning that, because there's always a cost - in my case, as a dude with a day job, the cost is in time with my family, my dog, doing fun hobbies, just relaxing and looking at the sky.
