I have a rental house on VRBO and on several other rental sites. I get the most inquiries from VRBO, by far. I do not have a management company but handle all management myself, including paying the taxes. Thanks for your help, ShallowsNole!
VRBO charges according to the number of pictures in your ad. You get five included in the basic price but they charge more for each additional picture. The additional pictures also move you up the list of rentals, so the more you pay, the more pictures you can have and the higher up on the list your rental will appear. I opted for the basic five picture ad. My rental is in Watersound so I figure anyone looking to rent in Watersound is going to look through the whole list anyway because there aren't that many listings in Watersound. Now if it were in Watercolor or another big community, it might be worth paying more to be higher up on the list.
VRBO offers a link to your other websites if you want it. I have mine linked to my Emerald Coast Tours site, which is where I have additional pictures. And speaking of pictures, IMO these can make a huge difference in how successful you are. Good pictures sell! So, unless you are a really good photographer, hire someone to do your pictures. Kurt did an amazing job on mine.
For proof, look at my pictures and compare them to rentals whose pictures were not done professionally. There is quite a difference.
