I took a look at the past 20 years of co-op and condo sales and pulled the highest closed sales for each year. I may have a few close seconds in the list. Co-op sales prior to 2006 were not a matter of public record so they were culled from our internal files.
The sales patterns show distinct eras that have been shorter in recent years (like the weather!).
Here’s my list – editorials welcome if I got any wrong. I’m going to continue to edit this list annually going forward given our market’s obsession with records.
