The local government puts a lot of emphasis on Walnut maintaining its traditional look and feel, and this is reflected in the large percentage of century-old houses that still stand in many areas. Buyers looking to move to this city can be optimistic in rising home values. The price appreciation last year rose 9.1 percent, from $64,300 to $70,166, allowing homeowners to benefit from a favorable, climbing market. During the same period, inventory declined by 25 percent. The number of listings in Walnut noticeably dropped from 4 to 3 homes on the market last year, somewhat constricting the market for new buyers looking to move to this area.
