I can understand your frustration. Nothing worse than the feeling of looking all over and not being able to find it. It looks like you have had some great responses from other Realtors on potential rental locations. Are you only looking for a duplex before you decide to purchase in a year, or would you be open to an apartment?
Please feel free to post any questions you have here and would be happy to get you any information you might be looking for.
Have a great weekend and good luck on your search.
