Utilize any hospitals and insurance companies that are willing to take your call.

Quote from @Max Pergament: Quote from @Matthew Irish-Jones:Licensed and insured to manage third-party properties. 

We have had a pipe burst during the cold winter months, the roof needed to be replaced (thankfully covered by our insurance), and some issues with electrical, which hasn't been majorly updated since it was built in 1973. 

Giving something fresh to the bathrooms rather than just matching the kitchen cabinets really gives the space a custom feel.2.

The proceeds could be reinvested into something with better returns or even used to simplify your finances(Like Bettment still offer 4.75% for new customers, and you don't need to do anything!).

Thank you to @Owen Rosen for helping me with the insurance on this one.

To my knowledge, guests also have trip insurance. 

Yes we avoid custom work to help keep cost down. 

Right now we're inquiring with our insurance provider to validate proper coverage, checking with our rental license if it covers uses like this, and working through what a lease would look like. 

(We're from California as well) Everything has been extremely smooth so far and their staff has been excellent with their customer service.
