Just curious if you can sell the lot after approval by the city and recorded with the county or do you have to wait for APN's to be issued? 

Syndication A: currently paying "projected" distribution rate.  

The seller is not very tech savvy and is going through some life issues so he isn't being very helpful in this.

The issue we had is that over time, our sheets get mixed up with other customers' (cheaper) sheets, and we ultimately end up with an inventory of sheets that are not ours.

Florida scares me with insurance issues and constant threat of hurricane damage.

This plays into the affordability issues for tenants by allowing them to live in nicer neighborhoods for less money, yet I get monthly revenue comparable to short-term rentals.

Anyone else having issues?

@William Causey depends on the transaction and the parties involved.Agree with @Dennis McNeely on some of the transaction costs.A different issue though is with an Assignment, the buyer gets to see what you paid for the property.

Major issues are lack of parking, lack of elevators, leading to numerous unlived in units.  

There's a good chance the issue(s) you face has already been discussed and answered.Ask questions in the appropriate forum.
