@Kamar0, I have also noticed some slowing down in bookings. I just looked at AirDNA and apparently, the number of hosts has more than doubled in the 3 years since I started hosting - so the competition is much more fierce. I did a search for Kingston JM on this Airdna.co site -
https://www.airdna.co/market-data/app/jm/default/kingston/overview
and found the following basic info: rentals on the market went from 282 in 2014 to over 2,300 in 2018... so the competition has become super-fierce. You can have a look and find some useful info even if you don't subscribe.
I use "beyondpricing.com" for my pricing - they take a 1% commission but I think it is very worthwhile. They adjust prices within a range I set and they have a lot of seasonality data, hotel occupancy, etc. and it is adjusted for events which I might not know about e.g. gaming conventions etc. I believe their site will have some good info for you (if they do JM, not sure...) - good luck!
