Somebody threw a chair or a brick through the front window I had installed last year.

Let me tell you I nearly fell off my chair when I read that hourly rate.Anyone know the average rate for a book keeper?   

Our next step is to try to replicate our experiment with a few more homes in our area, before building more software around it.Details- Desks: Ikea Bekant ($149); Chairs: Office Factor Executive ($199)- Room Locks: August ($199); Entrance Locks: August SmartLock Pro ($279)- Whiteboards: Quartet 3x4 ($199); Pin-Pong Table: JOOLA ($479)All in all, there were ~$10k in upfront costs less ~$4k recouped from sold furniture. 

a broken chair laying on the floor is obvious damage a crack across the TV is obvious then I'll contact the renter and have a discussion.

If it's merely a lot of out of towners buying and selling what they view as "cheap" assets to each other, and, accordingly, then you are likely seeing a bubble as that's usually just a game of musical chairs investors play.  

I physically got up my chair and started slowly clapping.

Reminds me of musical chairs.

The cost for building a wheel chair ramp would be carried by the tenant.

Didnt even have to get up from my chair. 

Everyone is happy and friendly if all is going well, but if there is a problem you are the one without a chair when the music stops.
