It reports 274 sales, an average sales price of $1,305,037.09, an average assessment of $826,690, and an average tax bill of $18,948.

Keep the geography and the question aligned
Municipality record
Westfield Town is the State taxing-district label for C/D 2020. Townwide averages cannot be assigned to a particular block, lot, or home.
Union County context
A Union County result does not become a Westfield town result. At the public portal, keep the selected county, period, and property category attached to every number.
Individual property
A property-specific CMA needs current comparable properties plus the subject property's condition, features, location, and timing. A municipality average cannot answer that question.
How to check changing 2026 conditions
New Jersey Realtors links to a public state-and-county reporting portal. Municipality reports are described as a member resource, so this page does not scrape or reproduce those reports. Use this workflow instead:
- Open the New Jersey Realtors market-data page and follow its public reporting link.
- Select Union County, the exact reporting period, and the available property category.
- Record the source label and period before comparing it with another report.
- Treat the result as county context only; do not assign it to Westfield or to an individual address.
- Return to the original source before a decision because public reports can be revised or replaced.
We link to the public source and do not reproduce its report tables. No affiliation or endorsement is implied.
A source stack for Westfield research
Each source answers a different question. Keep its geography, release, field label, and access date in your notes.
Westfield Town records
Use the official municipality site to locate the appropriate tax, construction, planning, zoning, or public-record office. Confirm the block, lot, and legal municipality for property-specific work.
Census ACS housing profile DP04
The 2024 ACS five-year Selected Housing Characteristics profile provides survey context for the named geography. ACS values are estimates for that release, not current transactions or appraisals.
New Jersey DCA Construction Reporter
Permit and certificate activity reported by local officials can help document construction activity. It is not current listing inventory and does not describe a future sale.
A reproducible comparison method
- Name the geography first: Westfield Town, Union County, or one property.
- Write down the publisher, table or report name, release period, selected category, and access date.
- Compare identical field labels only. Keep an average separate from a median and a survey estimate separate from a transaction.
- Use municipal and DCA records to investigate local property or construction questions; do not turn permit activity into listing inventory.
- Use current comparable properties and property details for a CMA; do not substitute a municipality or county figure.
The State row is quoted as published. The remaining sections are a research method and direct source map, not a copied market table or a property valuation. Compare homes only using the lawful property and transaction criteria you choose; this page does not rate people or neighborhoods.
