View source and methodology ↗How do citywide and neighborhood rankings relate?
Each area has its own ranking. A citywide count includes the agent’s qualifying homes inside that city, including its neighborhoods. Do not add neighborhood counts to the city total. A city boundary is different from the wider metropolitan area. These figures measure observed listing activity, not completed sales or service quality. Coverage is not complete MLS coverage.

How the listing data works
Scope & sources
What these figures tell you
Cribber measures observed listing representation using published geographic standings. Homes listed are distinct eligible properties credited to this agent or team; co-listed properties credit each named agent.
Asking volume uses listing asking prices and does not represent completed sales. Rankings do not measure service quality, buyer representation or negotiation outcomes. Coverage is not complete MLS coverage.
Keep the periods separate
Ranking dates appear with each area. Current property availability is separate from the published ranking. Historical samples, where available, carry their own dates and are not a complete career record.
