this is a very broad question. According to www.countyofriverside.us
there are over twenty-four cities in Riverside County:
Cathedral City, Blythe, Banning, Beaumont, Calimesa, Canyon Lake, Coachella, Corona, Desert Hot Springs, Hemet, Indian Wells, Indio, LaQuinta, Lake Elsinore, Moreno Valley, Murrieta, Norco, Palm Desert, Palm Springs, Perris, Rancho Mirage, Riverside, San Jacinto, Temecula.
In addition to these cities, there are also a number of unincorporated areas and smaller towns, such as Quail Valley, Menifee, Wildomar and Winchester.
With the current market conditions great investments are abundant throughout Riverside County. Crucial to your search is enlisting a Realtor to represent you as a Buyer's Agent. While there are hundreds of good investments out there, there are also a lot of overpriced homes on the market. Here in the Southwest Riverside county area homes in the same neighborhood(s) with the same floorplan and/or square footage can vary a staggering $200,000. Many people who live in this area relocate from another local city or neighborhood, knowing the area and knowing the local market conditions are very different.
David, also take into consideration what your investment resale timeline is. Are you looking to recoup an immediate profit, occupy the property as your primary residence or rent it out for a length of time. In addition to timeline price points are very important, for example, finding a $350,000 home in a $500,000 neighborhood may prove to be a good investment over time.
