@Chary0 I am glad to know that you have been doing very well. Like some hosts here mentioned by @Emilia42, @Paul154 , and @Cathie19 , there are so many uncerntainty and risks involed in operating Airbnb in the following areas
1. Safety and security risk: As a host, you are letting out your property to some strangers who are not screened by Airbnb thoroughly. Just one dangerous guy could ruin your property parially or entirely.
2. Risk of being delisted and kicked out by Airbnb without explanation. In this forum, many hosts have been delisted for no reasons or accused by some guests with lies. Some of them have thousands reviews with a number of listings.
3. Sustainability due to other factors. You may need to have a big heart and can deal with guests with various background, culture, characteristics in order to survive. And you also need to keep competitive in managing your listings in order to gain profit. With the more and more listings in the area, the difference between short-term rental profits are slowly approaching that of the long-term rental.
Good luck to us all hosts!
