Residents displaced by Superstorm Sandy are having a hard time finding a temporary place to live. Thousands of people are calling real estate offices, looking to rent apartments or homes. People are also looking for hotel rooms. Most are sold out. Many are occupied by out-of-state utility workers. Real estate agents say there are more people looking for rentals than units available. Agents are asking sellers to let displaced people live in their vacant homes. About 960 rentals are on the market in Monmouth and Ocean County, according to the Monmouth County Association of Realtors, but the number is fluid and probably lower.
