Why fix it if it's not broken, right?

You get a pie chart of income and expense breakdowns and then you can open up the bullets to the expense or income categories and it is further broken down as far as you have decided to enter categories for your data.Best I found is, this was a 30 day free trial and I just looked to check, it is currently listed as $119 a year. 

Tell Airbnb what was broken and we fixed it and tell them how much it was to fix and note that we will charge this after the guest leaves.

The tenant babbles about a broken down car, hours got cut at work, or whatever his excuse is.

He's broken the contract 10 ways to Sunday, should be easy to terminate--and anyway it ends on 12/31 this year.

Ideally broken down to the city at bare minimum, but even neighborhoods or zip codes would be even better. 

After you paid for a hotel for your tenants for the last week while the ac, the heat or the water heater was broken.  

Quote from @Jim Reynante: After owning properties C/D neighborhoods with high crime statistics, I have experienced all of the things that go along with it: 1) High turnover rate; 2) Tenants that don't care for the property; 3) Little/No appreciation in home value; and 4) High Crime Rate (burglary, vandalism).I am pretty tired of fixing broken windows, fixing broken doors/locks, and painting over graffiti.

For example, if I want to install new plumbing in the bathroom because the old one is old and broken, would I need a permit to do these fixes? 

In your case you can always buy broken duplex/SF and create value from there.
