San Juan Island Sales
Some interesting data here. December drastically outperformed last year in the number of sales but landed only slightly higher in terms of Dollar Volume.
- There were 18 sales in Dec 2025 on SJI and 14 were under $1M.
- 8 sales in Dec 2025 on SJI were under $500k.
- 9 sales in Dec 2025 on SJI featured single family residential; the other half comprised condo, commercial and VL.
- 4 sales in Dec 2025 on SJI were CB listings; one of the four was unlisted.
October followed closely with last year for both Dollar Volume and Number of Transactions. November, on the other hand, followed somewhat closely with last year in terms of Dollar Volume but saw a dramatic decrease in the Number of Transactions at both the Island and County levels.
At Year End
- Number of Transactions:
- SJI is 19% higher than 2024
- SJC is 11% higher than 2024
- Dollar Volume:
- SJI is 27% higher than 2024
- SJC is 19% higher than 2024
The high Dollar Volume sales during the summer of 2025 inflated the Dollar Volume numbers for the year. Without those we would be very close to last year; big luxury sales were not common in 2024 (nor 2023 and 2022 for that matter).
