I fixed a leaky roof, revamped the kitchen that time forgot, and transformed the backyard jungle into something a human could actually walk through.

I care about collections, not just bodies in the building.

I require proof of income, and verify it by contacting the human resources department of their employer in writing. 

Once you go through the whole process, you'll know exactly how it works in your area for the future.If the sweet nature of the dogs is what's bothering you, and how unfair it is that pit bulls as a rule are treated with what could be seen as deliberate malice by the media, give some money to the Humane Society to do more to advocate for the Cause.

Now do i think human activities can have impact on this, 100%.

After all, we're dealing with humans interacting with other humans.

I wouldn't do pets with carpet but then again I don't do humans with carpet either. 

I than thought it was tenants, all the "what if's"; what-if they have a fire, what-if there is a shooting, dead body, drug raid, break-in, squatters, feces art, etc etc etc.....   

These are humans we are dealing with and everyone is not the same so this is just part and parcel of owning ANY rental property..

You have fixed cost so it is better to get some bodies in there so you can get market rent later.
