HomeAway.com and their subisidary VRBO.com are engaged in false advertising. They want guests to believe that renting direct from owners will allow the owner to reduce the fee by eliminating professional managers. But owners who use the service want to eliminate the commission and get the money themselves. Guest and owner can't both get the same money. So that is the false premise.
Several years ago HomeAway raised $450 million dollars to buya nd buildng VRBO.com, CyberRentals.com, A1Vactaions and others. This has has been a disaster for advertiers (Owners and Managers). By overloading their sites with listings, the sites become unusable. Ad rates have sky rocketed but guest inquiries and guest qualifications have plummetted.
The only goal the HomeAway managers have, is to build up the thing big enough, go public, and cash out. They are not in it personally for the long haul. They are Internet geeks who don't understand the basic business premise that they must produce economically for advertisers. Hey even teenagers working at McDonalds understand it better than that.
Stay as far away from this company as you can.
