@Sanchit12 "Hosting" can mean many things. For example, you could become a tapeworm host, simply by consuming food or drink contaminated with feces that contain their eggs. No property necessary. But I can't say I recommend it, unless you're into extreme dieting.
If you want to host an Airbnb home, you have to get the property first. You can't list a space that doesn't exist. If you have a spare room in a rented house that you'd like to list on Airbnb, you have to make 100% sure that the owner permits you to do this, or you risk becoming homeless. Which I also don't recommend.
If you have no space at all and just like the idea of a hospitality career, apply for jobs in hotels, resorts, cruise ships, and/or restaurants. Or consider a specialized vocational training program, such as those provided by airlines, or a community college course in hotel management. These are ways that you can acquire skills that you can apply if and when you one day do find yourself with more property than you need to live in.
