@Basit Siddiqi Jacksonville is the 38th largest MSA by population just going off Wikipedia list from July 2023. Orlando is 21st in the list.
Truthfully I haven't compiled a list of the list of the number of total units being built for all cities, but when I would see the lists of the top 10 that Jacksonville was on as a percentage, many of the other cities had higher unit counts as well, like Nashville, Phoneix, Austin, etc.
I don't remember seeing Orlando being on those same lists, so I couldn't compare directly the total number of units being built for Jacksonville vs Orlando. Often the data companies put out the lists and you have to pay to access the data that would allow me to get more specific like this, so I can't do so.
Jacksonville probably is building more total units than some other larger markets, but I just don't have access to that information. So I may have misrepresented this a little, but that wasn't purposeful. My main point is that regardless of its size percentage wise its very high which has impacted Jacksonville a ton.
