I'm not entirely sure what you're asking here. Are you asking if there is a way to have a "list your rental on our site" page that has a data entry form that inputs to Owner Rez? If so, no there is no feature like that which I've seen. Something like that would probably be best with a plugin for your site or something coded to go into your database. Something like that, you're looking at a subscription model and there are wordpress plugins better designed for that and to handle the billing than Owner Rez is.
Now if you're asking about if you can create your own website that displays your listings and has a search feature, there are two options. Option one is using Owner Rez's hosted wordpress sites. That's the simplest way to go about it. Option two would be to design your own Wordpress site and use Owner Rez's plugins and widgets to handle the property display, search screens, bookings, etc. That's the option I chose.
