Census Bureau data continues to show that there's a steady stream of Americans leaving the suburbs and moving back to the city.

This is a reversal of the exodus to the suburbs that started after World War II. As the suburbs spread further and further out, they began segmenting into inner ring suburbs, outer ring suburbs and the far flung exurbs.

Today's "back to the city" movement presents some interesting opportunities for your wallet. In fact, inner ring suburbs are likely to see the largest appreciation in value, in Clark's estimation.

When buying in an inner ring suburb, it's a given that the neighborhood may have lost some of its appeal over the years. Therefore, try to find a neighborhood that's located adjacent to an area that's still on the up and up and looks poised for more growth.

Clark often looks at the cars in a neighborhood, or renovations and additions to homes, as other meaningful indicators of a neighborhood that's likely to gain in value.

Of course, there are never any guarantees in life!
