• At a 7% 30-year mortgage with 20% down, financing the median home here lands monthly principal & interest near $1,539 — before property tax, insurance, or HOA dues.
• Renting the median unit at $1,173/mo costs roughly $14,076 per year, or about 21.5% of the local median household income.

How to use this profile

Treat ZipLocal Guide as a starting point — never the final word — when you're researching a relocation. The Census ACS data on this page are reliable medians for the ZIP code tabulation area, but they tell you nothing about which side of the freeway you should live on, which streets the local high schoolers actually walk to school, or how the neighborhood has changed since the 2022 estimate window. For those, walk the area, talk to people on the street, and verify your assumptions with a local agent or community group.
