Derived findings
The 2026 single-family sale count was half the 2025 count: eight versus 16. The average increased by $2,307,255 while the median decreased by $468,000.
The average-minus-median gap expanded from $318,058 to $3,093,313. This demonstrates different behavior in the two price summaries but does not identify the transactions responsible. Eight sales are too few to ignore composition when interpreting either figure.
What this comparison establishes
The analysis compares the published January-August 2025 and January-August 2026 aggregates for Old Snowmass, 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.
