How we track the 10543 market
We built LOKAL to pull 10543's numbers straight from Zillow Research, so an agent and a client read from the same source. For July 2026 we recorded a $796K median sale price and a +11.5% month-over-month move with 38 homes for sale. We refresh every ZIP monthly from Zillow Research, which only publishes a smoothed median once a ZIP has enough transactions, so the median stays reliable instead of noisy. Both sources have published ZIP-level series for years, which is what lets us show month-over-month and year-over-year change here in 2026. LOKAL is independent and not affiliated with Zillow; always verify against your MLS before you publish.
