What most people want to know about a place when relocating is the cost of living, including rental fees and housing prices. In fact, that is a major factor in the long decision-making process. As you may have noticed, Bay Area towns are not the cheapest place to live. This is true for Walnut Creek as well. The overall cost of living index is 195.1, and the biggest influence on such a high index is the housing prices. If you are thinking of buying, you are looking at the median home value of $873,000, according to BestPlaces. If you are looking to rent and are already getting familiar with California renters' rights, expect to pay around $2,000 for a 1-bedroom apartment per month. Is it expensive to live in Walnut Creek? Yes, it's even more expensive than the California average. Is it worth it? Absolutely - this town is extremely safe and one of the best places to raise a family in California.
