The original article did not contain a documented ZIP-level price series. Here is the comparison framework to use when an approved, date-stamped dataset is available.
Define the market before quoting a trend
ZIP codes 78746 and 78703 cover multiple neighborhoods and property types. A quarterly median can move because the mix of homes sold changed, even when the value of a comparable home did not. Separate single-family homes from condos and identify the price band, time period, and number of sales before drawing a conclusion.
Unlock MLS publishes useful city and regional market reports, but a City of Austin median is not a 78746 or 78703 luxury median. We are not publishing an unverified ZIP-level appreciation figure here.
Compare like properties, not just ZIP labels
A useful review should include closed-sale prices, list-to-close ratios, days on market, active competition, and the number of comparable sales. It should also explain differences in lot size, home condition, age, views, and any HOA or waterfront characteristics.
For a low-volume luxury segment, a handful of unusual sales can move a median sharply. Show the sample size and use a wider date range or a property-specific comparison when one quarter is too thin.
What to request before making a decision
Ask for an MLS-approved, date-stamped analysis of the exact property type and geography you care about. Check the source and calculation method, and distinguish asking prices from closed prices. A seller's pricing or buyer's offer should then be grounded in genuinely comparable homes, not a broad ZIP-code headline.
