During walkthroughs I have seen that her unit is pretty untidy and she also has 2 cats that she has not paid a pet deposit for.

Dealt with all the expected.. extra people living in the house, extra pets, expected damage to walls from nails etc etc.

Or if you allow pets, it's always great for them too.

@Mindy Jensen I think one of the worst, was when a tenant moved out, we went to do move out and turn the home, found a dead dog in a cardboard box in the garage.During a routine inspection, on a tenant with no pets; a room full of spiders and snakes.

The Rabbu revenue by amenity analysis suggests allowing pets in Snowshoe, WV (a market I'm familiar with) adds an average of $328k/yr to the average property. 

This contains all your qualifications, income = 3 x monthly rent, no evictions, no credit issues, no co-signers, no pets, no smoking or whatever your requirements are.  

In this case all pets will likely have pet rent.

The apartment smells horrible due to the tenant allowing her pets to urinate all over the place.

I have stayed away from renting to a pet owner in the past, but I feel like more and more people have pets.

Airbnb will release more money sooner if you pay for the privelage to get your money.Airbnb has no place to collect pet fees either.
