Received a phone call this afternoon Canceling our Oceanfront Mid May rental. We signed the lease on May 31, 2020 and paid for it. A signed lease and payment acceptance means nothing! So -As the story goes, "The owner also had it listed on airbnb and we now have a double booking" The owner is going to honor the airbnb rental.. Sorry!
We were offer two non oceanfronts claimed to be an upgrade - NOT.
I cannot believe this BS is allowed and people tolerate the shenanigans that have went on down there this last year. I have a call into one of the other realtors and did find a house that sort of suits. At this late date, you take what you can find. SO even if you have a rental for nearly a year you are subject to the whims of the owner, and by default the rental management firm.
As an owner, I can say that nothing keeps me up at night more than the fear of a double booking. Knock on wood, it's never happened to me, but when you advertise on multiple platforms (which virtually everyone does) the possibility exists. Actually I've heard of PMs double booking.
Nevertheless, the first booking should always win. It sounds like the owner either got more for the Air booking, or feared to ranking penalty associated with an owner cancellation.
As for your options, depending on what's in the contract, you could sue the owner for breach of contract. I doubt the ROI on legal fees or effort would be worth it.
If it's any help, I do have the two middle weeks of May still available at our place. It's not oceanfront, but it's a 5br with pool in Frisco. As you can imagine, things are booking up quick this year.
