On Airbnb there is one price displayed on the map (the daily rate), then when you click on a place, the fees are added and the price changes. But that still doesn't include tax and local fees which add more to the price when you go to confirm. So what you see on the map is quite less than the final price.

I believe there are laws in some locations that make Airbnb show the price upfront on the map and they do for those places. But it doesn't seem to be the norm in the US.
