Observations generated from ClearKey's dataset. All statements are derived from measured data — no subjective assessments.
Selling time broadly in line with the Northern Ireland average
This agent's median of 110 days places them close to the Northern Ireland median of 101 days. This suggests performance consistent with typical market conditions during this period.
Ranking based on a relatively small number of transactions
This agent's ranking is based on 11 qualifying transactions, which falls in the lower confidence bracket (10–14 transactions). With fewer data points, the median is more sensitive to individual outliers. Treat this ranking as directional rather than definitive.
Wide variation in selling times — 89 to 131 days for the middle 50%
The middle 50% of this agent's listings sold in 89 to 131 days — a spread of 42 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 176 of 200 qualifying agents this period
This agent's rank of 176 out of 200 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.
