Risk is not just limited to the behavior of guests. As a property owner myself, here are some of the risks that come to mind when I think of turning one of my long term rentals into an Airbnb:
-Seasonality of income/demand throughout the year.
-Regulations (Airbnb/STR is regulated on a city-by-city basis and can change at any time).
-Increasing competition from ever-more airbnb units coming online, reducing demand for my unit and lowering rates.
-The sunk cost of furnishing the home.
-Airbnb property management companies in general are in a bit of a limbo state right now with regard to regulation by the State of Ohio Division of Real Estate. If you call and talk to them about it, you will find their opinion is that they must be licensed just like a normal property management company or real estate brokerage. Yet several airbnb management companies are operating without a license and claim they do not need one. Who knows how this will play out.
-Risk of hiring a young/new company to manage my property. How do I know they will actually provide transparent accounting and remit all funds to me that are owed. Especially if they are claiming they do not need a license and are unregulated by the state.
-The risk of a lawsuit or liability incident goes up with so many people coming through the door every month.
-Risk of my insurance company not covering a claim if they find out I'm hosting short-term rental guests OR having to pay for more expensive insurance to make sure I'm covered. Airbnb's host insurance is notoriously useless.
-My neighbors might be pissed off about me running a STR and call code enforcement or otherwise be a nuisance. Or maybe I like them and don't want to make them mad.
That's just off the top of my head. Some talking/thinking points for you to consider as your work on your marketing and business plans.
