Hi @Michelle1562, first you have to let us know what you heard so that we can tell you if it is true or false but most importantly you need to learn the rules and regulations your city requires in order to host. But once you get all the technicalities in ordes, hostins is wonderful, you will meet a lot of new people and maybe make some new friends, the extra cash doesn't hurt also 🙂 But as with everything, there are bad sides so you need to be prepared.
From my experience, don't even try to host without going through the business license process. You are setting yourself up for failure if you do it illegally.
