In addition to airbnb and other booking sites, we reached out to the many, many, many realtors in our town and market the home as a short term rental for people "between houses."
It happens a lot more than you think. We currently are leasing our home for 90 days to a young couple with kids who sold their home locally in February and won't be able to close on their new home until May because of the sellers construction on their new home.
The revenue is not quiet as high as airbnb, but this time, it happened in the winter months when occupancy is a little less. Plus, it's a nice break from cleaning.
We make them sign a standard lease agreement. They get a fully furnished nice home with utlilties paid for during their 3 month stay.
