No recent sales or for-sale comparisons. Good or Bad?

[Brian Brigham]

Large neighborhood with hunderded of homes has one foreclosure for sale, but there are no recent sales and no houses for sale within that neighborhood, or ~1 mile surrounding (info based on website searches). Does that mean anything? Is it possible to ascertain how difficult it will be to resell. Is it a good sign that no one has sold, or is trying to sell in this area, or is it just too risky to understand what the demand may be in the area?
