I used Flipkey for 5 years, until now everything has been good, now they restrict the user info from the owner that does not allow them to make sure the renter is a good choice and is not a criminal or scammer.
The proof is in the numbers, my accountant turned in my last 3 years rental numbers, they are below, this year flipkey didn't get nearly enough numbers to pay my expenses and now this property is costing me money in overhead cost.
Despite people traveling more, bookings are down a huge %. Below is the yearly rental amount.
2017- $39,094.78.
2016- $62,050.21
2015- $73,394.55
Numbers do not lie, do not recommend anyone list and pay for this service. I do not know why they are not getting any inquiries any longer (but they still have the hand out every year for me to pay them and for the customers booking fee) but they are no longer a good option for renting a vacation rental home.
