San Diego County is one of the most expensive places to live in America. Even so, several communities remain relatively affordable.

Known for its great weather, diverse mix of cultures, exceptional cuisine, beautiful beaches, and bustling social scene, San Diego is one of the most popular places to live in the country.

As home prices continue to rise, affordable San Diego neighborhoods become increasingly scarce. However, there are still several places where home prices remain relatively affordable.

The central and northern communities of San Diego tend to be the most expensive. You can find much better deals in eastern and southern communities. But as the county becomes more popular, it may not be this way for long. Currently, these are the most affordable San Diego neighborhoods:

El Cajon

The sixth largest city in the county, El Cajon remains one of the most affordable places to live in San Diego. The city boasts a vibrant and diverse community full of attractive residential neighborhoods, well-maintained parks, popular recreation and social centers, high-performing schools, public libraries, and other communal amenities.

Taylor Guitars, among the world's top guitar manufacturing companies, is headquartered in El Cajon. The city is also home to Parkway Plaza, a sprawling retail mall with over 170 stores, restaurants, and entertainment venues. These include Regal Cinema, Best Buy, JCPenney, Dick's Sporting Goods, and so many more.
