Not unusual at all as more HOAs and Condo Associations deal with real and perceived problems of rentals vs owner occupied  

However, be aware of the unusually high insurance costs in Florida, exacerbated in recent years by climate-related events.

Like this post, which is unusual because it starts with a great deal.  

I tried offering 2 year leases for a little while but tenants were leery of the long term commitment maybe because they were new to me and a longer lease seemed "unusual" to them and therefore scary.

Is this unusual?

While this is not normal, it is not really unusual. 

The property also has unusual price changes and sale listings and is asking for ~100k above assessment (2022).

We haven't decided yet if we wanted to explore ADU opportunities (for now it's less about investment value in the short term--more for family planning) but at the very least I see that there are a bunch of homes that seem unusually small given their lot sizes.

It sounds too flakey to be real....Trust me that in Miami, this is not so unusual.

The house itself is on a flat road and if you go out the other direction it is not an unusual hill for the area.
