Home builder undone by Valley market

``Randall Martin Home decided it could not afford to complete four subdivisions it has started around the Valley, a company spokeswoman said. The decision to walk away from its vacant property and unsold homes has left people who have purchased and moved into the builder's houses worried about their neighborhoods.'' -- This has to be the biggest case of "walking away" we've ever heard of. No word yet on whether there was a formal bankruptcy filing.
