Market demand data


I would like to invest in one or more properties in New locations. I was wondering if there is a data set that would help me identify the market demand of the areas I am looking to invest in. I did find some external sources for the US, but hard to find this for other countries. I am looking specifically for locations in India. I see that booking.com provides a market insight api, but I was not able to use it as it requires its own credentials. Can somebody help me with this or provide a contact person whom I can reach out to
