This is more of of MLS and how they send the info out. The best way is to check in with a realtor. If you already have one you have been working with call them.
If not I can be reached via my Cell # 757-999-4670. We do not have many rentals at all and the good ones go fast. This past week I just rented 4 units. We do have a couple more and do not forget the local paper Eastern Shore Post. Also via the internet http://www.easternshorepost.com. Every Friday new ones will come out and you would be dealing directly with the owner.
