Good news is you have a previous owners track record to give you a little foreshadowing into what worked for them and how to build from their wins and fails.

I spent the majority of that time traveling the country for small public company that had a niche in acquiring owner financed land notes.  

Trying to get an idea of total costs to get the sites setup.

Olympic sized pool, hot tubs, on-site restaurant, yoga, pilates, gym, steam, sauna, and management company to take care of it all.

This means you must be the title owner of the property for 12 months until you can use the appraised value of the property.  

I cannot find a site where I can enter the parcel number to see if STR is permitted.

Warning: avoid unfamiliar sites, as many of them are scammers phishing for your personal information.Just remember that the real numbers will be different in the end.

If you are in a condo building look at Section 718.110(13), Florida Statutes, provides as follows: “An amendment prohibiting unit owners from renting their units or altering the duration of the rental term or specifying or limiting the number of times unit owners are entitled to rent their units during a specified period applies only to unit owners who consent to the amendment and unit owners who acquire title to their units after the effective date of that amendment.”

The Sold properties will show you what these deals are actually trading for.In addition to this, since you're interested in multi-family properties, you'll also want to look up recently Rented apartments on these sites.
