Affordability in this ZIP
Derived from the Census medians above — indicative, not an offer.
A rent burden above 30% is the federal threshold for cost-burdened households, and a price-to-income multiple above 4× is generally considered a stretched housing market. The mortgage figure is principal and interest only — taxes, insurance and HOA dues are extra.

- Is a ZCTA the same as a postal ZIP code?
