We should recognize March 2017 as one of the strongest months for closed listings, with 9,272 over all areas & types. This is the highest monthly total since May 2013 and the highest total for March since 2005, making it the second most successful March ever.
To be fair, March did contain 23 working days, the highest number we ever see in a month, so we should have expected a big number. But March 2016 also had 23 working days and only managed 8,363 closed listings.
