Market-State Adjustments: When Closed Comps Lie

Closed comps describe yesterday's market. In a stable market that's fine. In a rising or falling market, an unadjusted closed comp from 4 months ago is misleading. Apply market-state adjustments or build CMAs the appraiser will reject.

The rising-market adjustment. Compute the monthly appreciation rate from the last 12 months of closed transactions in the price band. If prices rose 0.8% per month, a 4-month-old comp gets a +3.2% adjustment to reflect current market value. Document the calculation explicitly in the CMA so the appraiser can see the methodology.

The falling-market adjustment. Symmetric. Falling 0.5% per month means a 6-month-old comp gets a -3.0% adjustment downward.

The flat-market case. Don't apply adjustments where the data doesn't support them. Forcing a 'small adjustment' on a flat market makes the CMA look manipulated.

Pending and active integration. In rapidly changing markets, recent pending sales (last 30 days) reveal trajectory better than closed sales from 90+ days ago. Use pendings as supporting evidence and as a check on the closed comps' applicability. If the pending median list-price is 5% above the closed-comp median, the market is rising and closed comps need upward adjustment. If the active median is 5% below recent closed comps, the market is softening and closed comps need downward adjustment.

The appraiser's framework. Appraisers use 1004MC (Market Conditions Addendum) which compares current to prior 6-month period. Familiar with the structure means the agent's CMA aligns with the appraisal's framework—reducing the chance of an appraisal-driven re-trade.

What trips agents up. (1) Reflexively using the last 6 months of comps without checking whether the market moved. (2) Cherry-picking the comp that supports the desired number rather than running adjustments transparently. (3) Failing to update the CMA between listing and offer acceptance—market shifts in fast markets within a 30-day listing window.

The practical move. Rebuild the CMA before any price-adjustment conversation with the seller. Walking in with 'the market shifted, here's the new analysis' is more credible than 'we should reduce because it's not selling.' The data-driven framing turns a hard conversation into a market conversation.
