While this hasn't been needed in the past, I’m considering if it could help prevent tenants from reporting problems later that they claim existed when they moved in.

The only reason that it can't really be used as currency right now are the fees are too high because it's running into scaling issues, and the volatility is preventing anyone from trusting it as a day to day currency.

The way my lease reads the tenant remains responsible to pay rent and utilities to "prevent waste of the premesis."

I was worried about it, but so far no damage or stains and we allow dogs.

There is nothing that prevents you from shopping around early to see what's out there.

With a full time job even 15 units gets tough between collecting rent keeping repairs up, preventative maintenance, looking for new deals, managing refinances, etc. 

Prevent financial loss.

The second option is that she go to court, where she will lose, you get a judgment for everything owed including cleaning and repairs, and then you send her to collections where it will prevent her from qualifying for another rental, getting a car loan, etc.

To be clear, we inherited the house, but there is a complication that prevents us from being able to sell it for a few years, but we will eventually sell.

For prospects seeking to rent many months in advance we are typically declining those and seeking to lease up as close as possible to the next available date so as to prevent potential gap periods that will be harder to lease.
