Stockton has the highest number of foreclosures in California -- one in every 50-households, according to RealtyTrac.
One city official says spray-painting a lawn green makes a big difference.
"Turns the grass green, and lasts for three months, and looks decent again. I'm very pleased with the quality of it," said Ron Girard, city of Stockton.
"It's a win-win for everybody, for banks, city, realtor, even neighborhoods. It keeps them looking nice," said Nick Terlouw, Greener Grass Company.
It generally costs about $200-dollars to paint each lawn. He uses a water-based dye --the same kind used to paint logos on football fields.
