I'd probably try FB marketplace first and see how it goes, then if that doesn't help look for a good advertising platform like buildium (which is probably too robust of a tool for what you need right now, but something with just that advertising feature).  

Airbnb/VRBO do bring in about 60% of our bookings but that does leave another 40% to direct bookings and a combination of our other platforms (Marriott Homes and Villas, Booking.com, JetBlue and Allegiant Airlines, Google Vacation Rentals, and more). 

What is decent rate for fix and flip who starting first deal.

We ran the numbers, analyzed the property multiple times, and based on AirDna, and other platforms, it looks quite promising.

There also seems to be a monthly fee for using the platform.

JADU is even worse re investment than an ADU.In general ADU additions in single family zones are not decent RE investments.  

Striving to put out great content on all platforms.

My apologize if I am on the wrong platform. 

A lot of us here on this platform are willing to help any way we can. 

Hi @April Vogt, I agree with Erwin, Idealista is by far the most used platform for Real Estate in Spain, so the best source for getting info.Then it depends on what you want.
