Dave,
I assume he was asking for declining market status, I gave him a list of declining market status zip codes. I'm sorry you find that useless, but you didn't ask the question.

If you are referring to "declining market status", requiring more funds down, it's been eliminated. If, however, you're asking if the market in that area is experiencing decline, you might call a real estate agent and get recent solds in the area that you are considering, as well as solds from six-nine months ago.
Good luck!

Zach, thank you once again for providing absolutely no insight. Its pretty interesting the connection between intelligence and those people that say they want to be "filty rich" and retire early. You probably won't get this post, but oh well...
