Hi Annet, my name is Nuwan, I am a Sri Lankan and a hospitality professional who has 12+years hotel background. Currently I own my own airbnb place and living a simple but a happy life.
Since you are a foreigner who own a property in Sri Lanka, you can rent and manage your property while you are out of SL. As long as your accommodation payment received to your non resident bank account ( non Sri Lanakn bank account) you will not be taxed.
However, you need to find some trustworthy people to maintain your property and host your clients. That's the challenging part.
Then you can list your property on Airbnb and when you receive bookings, you can do the coordination part with clients and the co-host.
