How we track the 99350 market
We built LOKAL to pull 99350's numbers straight from the Redfin Data Center, so an agent and a client read from the same source. For May 2026 we recorded a $423K median sale price, -8.1% year over year, a 96.8% sale-to-list ratio and a -7.6% month-over-month move across 41 recorded sales. That compares with roughly $460K a year earlier, in 2025. We refresh every ZIP monthly and only publish once a ZIP clears at least 20 recorded sales for the period, so the median stays reliable instead of noisy. Redfin has published ZIP-level market data monthly since 2020, which is what lets us show month-over-month and year-over-year change here in 2026. LOKAL is independent and not affiliated with Redfin; always verify against your MLS before you publish.
