Honestly. I have no idea where these numbers are being referenced from. In all of Miami-Dade, as of the time I type this, there are 1,855 closed transactions for single family houses, condos, villas and townhomes within the last 30 days.
If we add those now with a contract Pending or seeking a backup contract but not yet closed, this adds another 3,823 properties to the mix within the last 30 days.
As mentioned by others below, there is more than one way to analyze data.
Also, one of my biggest pet-peeves is to see an article talking about South Florida's real estate market where they throw the name "Miami" in (I guess to catch the reader's eye), all while speaking about the tr-county area statistics and without specifically, braking it down for each county. Very confusing and misleading, to say the least.
Just for good order, as of the time of this writing, there are 22,431 single family houses, condos, villas and townhomes available for sale in the MLS and in Miami-Dade county.
