@Cari3 Some hosts have posted here saying they did some in depth research in their area and that those messages are quite obviously BS. I think it's just a ploy by Airbnb to get you to lower prices so they can charge a higher booking fee.
I do think some newer, not so savvy hosts way undercharge as they think they should be following the price tips and offering discounts.
I just ignore all those messages, altho if I'm feeling snarky that day I sometimes check the box "Was this helpful?" as No and then fill out the feedback box telling them I'm not interested in renting my lovely private room with private bath and full kitchen use for the price of a fleabag motel and that their tips are offensive.
