Thousand Oaks in Ventura County is known as a safe and quiet city in California, and within it, the North Ranch area has formed a higher price tier. It is a gated community with golf clubs, where the median home prices have risen to between $1.9 million and $2.2 million.

Lake Sherwood and Hidden Valley are also frequently mentioned when discussing luxury neighborhoods near Thousand Oaks. These areas are characterized by large estate homes surrounding private lakes, and they have long been known as vacation spots for Hollywood celebrities, building their reputation over time. The median prices often exceed $3 million, and large parcel ranch properties are traded for even more.

Westlake Village is another area that is often mentioned. It is a planned community centered around an artificial lake, where the median prices for lakeside mansions and homes near country clubs are around $1.8 million to $2 million.

The background for these areas becoming luxury neighborhoods includes the geographical privacy provided by mountains and lakes, along with accessibility being just about an hour's drive from downtown Los Angeles. In comparison, the overall median price in Thousand Oaks is around $900,000, making North Ranch and Westlake Village more than double that level.

Unlike Westlake Village, which was developed systematically since the 1970s, Lake Sherwood and Hidden Valley represent a gradual transition from ranch land to upscale residential areas, making their development processes quite different even within the same living zone.

Among Korean professional households, North Ranch and Westlake Village are relatively preferred due to their excellent school districts and stable communities, while Lake Sherwood is still mentioned mainly among a few affluent individuals due to its high entry barriers.

The Thousand Oaks area has consistently attracted families looking for relatively larger lots and a quiet living environment compared to Los Angeles. It is advisable to consider whether to go for North Ranch or choose an area at the overall average level of the city, taking into account school districts, commuting distances, and budget.
