Hello @Parmi12
you would probably attract booking if you photographed all the rooms in your house , labelled your photos and wrote a fuller description of your property detailing rooms, key amenities and your location
check with your competitors to see if your pricing is competitive.
owners normally look for cohosts who are experienced hosts themselves who understand how to market properties , how STR platforms work, and who have great ratings and reviews .
it would probably be better to update your listings , hopefully gain some experience and great reviews before you try and offer cohosting services to others @Parmi12
you can find information about cohosting on the Airbnb Help website .
this is an international community to ask questions relating to Airbnb.
Speak to a local commercial estate agent if you want advice on commercial let's.
