Hello @Sherien2 ,
In Mangalore and any other future properties you have, consider first checking all the properties in the vicinity on Airbnb, because this is what your potential guests will see. There, you will observe pricing strategies, occupancy rates (check others' calendars to see how busy they are), and it will also help you distinguish yourself with how the space looks.
You can also use a website called AirDNA. Even their free version can give you a good understanding of what is going on in your area regarding Airbnb properties.
I hope something from this will help you.
Good luck with hosting.
