When a Bethesda price statistic appears precise, it is easy to give it more authority than its definition allows. In late summer 2026, the public figures included a $1,121,468 Zillow typical value, a $1,206,700 Zillow median sale price for July, a $1,349,107 Redfin median sale price over three months, and a $1,212,450 Realtor.com median listing price for September.
The Bethesda price-measures report keeps those values separate and shows why.
An index is not a closing price
Zillow describes ZHVI as a measure of typical home values that captures monthly changes in property-level estimates. It is designed to track a market over time. A sale-price median, by contrast, is the midpoint of the homes that closed during a defined observation period.
If the mix of completed sales shifts toward larger houses, newer renovations, or a different property form, the transaction median can move even when a constant home would not. That is one reason an index and a sale median should not be expected to match.
Asking and sold medians are not a matched pair
Realtor.com reported a $1,212,450 median listing price and a $1,280,000 median sold price in its September summary. The arithmetic gap is $67,550, or 5.57% of the listing median. That calculation does not mean the typical Bethesda home sold 5.57% over asking.
The active listings and completed sales are different populations. Their property mix and timing differ. Realtor.com's own sale-to-list ratio was 98%, which is the more relevant provider metric for asking-to-sale relationships.
Price per square foot also needs a matched set
Realtor.com reported $427 per square foot and Redfin reported $449. Even a properly calculated price-per-square-foot measure cannot capture lot, architecture, condition, level, exposure, view, parking, outdoor space, building quality, fees, or documented renovation. It is a diagnostic, not a complete valuation method.
A better property-pricing sequence
- Define the exact property and decision date.
- Select the smallest credible geography and matching property form.
- Separate closed, pending, and active evidence.
- Document why each comparable belongs and how it differs.
- Verify listing history, concessions when available, and material condition.
- Test the conclusion against current alternatives.
- State the remaining uncertainty rather than filling gaps with a portal median.
For sellers, this sequence helps distinguish an evidence-led launch price from an aspirational one. For buyers, it helps separate a broad market anchor from the price and terms justified for the subject property.
