The rental environment is more competitive than ever. With the economy improving, more vacation homes are being built. This means more options for the renter. Add in VRBO, Homeaway, and now AirBnB and there are more choices than ever before. This makes it more difficult for your home to even be noticed, much less chosen. Property owners need as much exposure to their target market as possible, and when you can accomplish this at virtually no cost, it only makes sense.
