From the emails it looks like from the responses the property you are interested in is either expired, withdrawn or cancelled. That is pretty frustrating and time consuming only to find out the property you like is missing. Really, the best resource is two fold, access to a real estate website that is updated as soon as listings are changed and a Real Estate agent working for you. Best advice you can have all day.
Feel free to log onto my website http://www.theconciergerealtor.com and sign up for listings that are time sensitive and updated constantly.
I think there are more for sale than you can see here.
Most professionals even know of ones like this one that are secretely on the market.
They are called "pocket listings."
I'd choose a real estate professional and go buy one!
