Do you have a professional real estate consultant who can guide you through the process of purchasing the property? It is very important to rely on trusted agent to help you make best business decisions but also supply you with the current and valid listings. These you are looking at are for 180+ days on Trulia and don't seem to be currently listed for sale.
If you need an assistance which is free to buyers please contact me at your earliest convenience I would be happy to help you.
