I can understand your frustration but let me clarify, if you are asking about the rentals in 08008 zip code maybe I can help you understand a bit better. If this is not related to the 08008 rentals then my answer would be different. I will also agree with Kenneth, this is not the catagory to post this type of question, it should be in the "agent to agent" posts.
The fact is as an agent you should call to pick up a key and preview the properties , then get your questions together for the listing agent. After all if you are selling/renting Real Estate, it is your job to know the inventory, not depend on the listing agents to fill you in.
Once Sandy hit LBI, we had a tough enough time finding rentals in homes that were undamaged. The people that needed to be placed here are those working to rebuild the Island and it has been very time consuming to help these contractors and owners who had many questions and concerns. . Another problem is since it is a summer resort, most owners are fearful of putting a tenant in a house that will be difficult for them to leave because their home is still damaged. These owners need to have their property available for the summer tenants, not extending a winter lease.
I think the mentality here is the less information in a listing, the more questions tenants and buyers will have and it prompts a call. I have never been too busy to answer questions for anyone calling on my listings, nor have I ever found another agent too busy for mine. Unless of course they are involved in a Short Sale and do not have the answers you are looking for. I wish you the best of luck in the business.
