Derived findings
The median-price difference was positive $288,900, whereas the average-price difference was negative $179,733. Opposite directions in these two summaries make the transaction distribution important to interpretation.
The sales increase was six transactions on a base of 12, producing a 50.0% percentage change. The relatively small denominator should remain visible alongside that percentage. August inventory increased by ten listings.
What this comparison establishes
The analysis compares the published January-August 2025 and January-August 2026 aggregates for Basalt, Colorado, using the property category shown in the tables. Inventory and months supply retain their separate August reporting frame.
The public PDF supplies aggregate results rather than the underlying transaction file. It supports reproducible arithmetic and descriptive comparisons. It does not support a causal explanation, a like-for-like appreciation estimate or an address-specific value. The companion article develops the practical questions raised by these findings.
Methodology
- Use the official Aspen/Glenwood Springs MLS Inc. August 2026 Local Market Update, current September 3, 2026.
- Transcribe the named geography and property-form table. Compare its January-through-August 2025 and 2026 values.
- Calculate displayed percentage changes as (2026 minus 2025) divided by 2025, rounded to one decimal. Retain the report's separate August inventory and months-supply measures.
Limitations
- This is an aggregate public MLS report, not an appraisal, forecast, causal analysis, or full Roaring Fork market measure.
- Median prices do not account for seller concessions and/or down payment assistance, as stated in the source.
- One month can look extreme due to small sample size, as noted by the source. Inventory is an August snapshot while sales values are year-to-date.
