How we track the 18104 market
We built LOKAL to pull 18104's numbers straight from Zillow Research, so an agent and a client read from the same source. For July 2026 we recorded a $381K median sale price, -0.2% year over year, a 102.5% sale-to-list ratio and a +2.4% month-over-month move with 94 homes for sale. That compares with roughly $382K a year earlier, in 2025. 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.
