Under F.S. 83.595, landlords have 4 options when a tenant terminates early, one of which includes charging the tenant an early termination fee (no more than 2 months' rent), but if your lease agreement does not provide for liquidated damages upon a tenant's early termination, you have only 3 options as a landlord.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

I didn’t paid the 10% penalty fee. 

Have you considered getting a pricelabs subscription and getting a little more in depth #'s on amenities, management experience, review count, pools, view vs non-view, etc?

The appraisal costs on something like that would be pretty high as well.If you go the single asset route, you might get a nice little discount on fees by doing multiple at once.

Some states also require an annual license fee to own and operate an LLC so that could also cause a potential for increased costs there as well.I would consult with a real estate attorney to see if an LLC makes sense from a legal standpoint and advise your accountant as to your decision so the appropriate tax filings can be made.
