And, here's the law on tenant abandoned property in Florida:  https://www.nolo.com/legal-encyclopedia/handling-tenants-abandoned-property-florida.htmlThe owner/landlord/PM may enter the property, inventory (I recommend photographing) items left behind - and assess damages to your property. 

Agree, it doesn't have enough information to assess.

Then you have the added 'commercial' tax assessment & of course there's the trash pickup penalty.

I looked up the tax assessment as it said 32285.

I largely agree with your assessment, @Chris Martin. 

On top of that my mortgage company sold the mortgage to another company, they did a tax assessment and decided it was priced way too low and I owe a year back on prop taxes to make up for it.

If that’s the situation, I would ask the owner to hire an inspector to do an assessment of the structure and what work needs to be done.

Additional parking would impact the value directly, but you have to assess the current parking ratio of the buildings and see if there is actually a need for it.
