You can go to CFRI .net and look at the calendar.   

Pick a couple listings that look similar to what you are thinking of doing, follow their calendars throughout the year and see how booked they get. 

@Mike Ojo, I do not own any there, but your best resources would be to go on airbnb and find areas that you liked or think would do well and go through their calendars for their rates at different seasonalities. 

Every area has seasonality so if it stresses you out to see an empty calendar, it may not be the best strategy for you.

If you check rental company calendars, bookings are very strong for this year.

There is a calendar section in our pricing tools that compare our nightly rates with comparables and we can see how much more we are getting. 

Also changing the calendar regularly so you get put back on the top of the list.

Get an idea of the price, the recent reviews, and look at the calendars to see how many future bookings they have.Start listening to some Airbnb podcasts.

Look at properties in your area, click on their calendars to get an idea of occupancy.

and just make sure to get a channel manager software that way it will sync all the calendars for all the listings together to prevent double bookings (a hosts worst fear)
