Speed to sale agreed is one indicator of performance, not a comprehensive measure of service quality. It does not capture price achieved relative to asking price, fall-through rates, or quality of buyer qualification. Simon Brien (North Down)'s position in the lower half of the ranking may reflect the types of properties they handle rather than service quality — agents specialising in higher-value, rural, or niche properties typically take longer to sell. Compared with October 2025 – April 2026, Simon Brien (North Down)'s median improved by 148 days.

Observations generated from ClearKey's dataset. All statements are derived from measured data — no subjective assessments.
Selling time of 117 days — below the NI average
This agent's median of 117 days is 23 days slower than the NI median of 94 days. This may reflect the types of properties this agent lists, the price bands they operate in, or the postcodes they cover rather than service quality directly — slower markets affect all agents.
Selling times improved compared with the previous period
This agent's median dropped from 265 days in October 2025 – April 2026 to 117 days in April 2026 – October 2026 — an improvement of 148 days. The Northern Ireland market median moved from 204 to 94 days over the same period.
Wide variation in selling times — 56 to 140 days for the middle 50%
The middle 50% of this agent's listings sold in 56 to 140 days — a spread of 84 days. This breadth suggests the agent handles a diverse portfolio where individual property characteristics have a significant effect on how long each takes to sell.
Ranked 186 of 196 qualifying agents this period
This agent's rank of 186 out of 196 reflects their speed relative to the NI market during this period. Rankings can shift from quarter to quarter based on property mix, market conditions, and data volume.
Days on market is calculated from the property's listing date to the date it moved to sale-agreed or likely-sold status — not to legal completion.
Median is used as the primary ranking metric rather than average — it is more robust when individual portfolios contain outlier properties that take unusually long to sell.
Only agents with a minimum of 10 qualifying sale-agreed transactions in the analysis period appear in the main ranking. Segmented breakdowns (property type, price band, region) use an adaptive minimum between 3 and 10 transactions, scaled to the total activity in that segment — this prevents niche segments from showing almost no ranked agents.
Properties with a days-on-market figure exceeding 1,095 days (3 years) are excluded as likely data anomalies.
All data derived from ClearKey's verified Northern Ireland property listings database. Rankings are computed independently and cannot be influenced by estate agents.
Speed is not the same as price achieved. This page measures how quickly listed properties moved to sale agreed — not whether they achieved asking price, above, or below.
Area effects. Agents operating in postcodes with naturally faster market velocity will tend to rank higher regardless of individual firm performance.
Property mix. Agents handling premium, rural, or specialist stock that takes structurally longer to sell may rank lower without any reflection on service quality or client outcomes.
Name fragmentation. The same firm may appear under slightly different name variants in listing data, which can split their transaction count and affect ranking.
