I'm sure it varies by area.Start by giving the tenant notice that they need to pay the utilities or get out and you want proof that they are paid by a set date. 

Application / documentationYou will need to submit: a completed STR permit application, letter describing proposed rental use, floor plan, copy of a blank lease agreement, proof of ownership.Fee: The application fee is cited as about $63 for the application / two‐year permit in many guides.Tax obligationsHosts must collect and remit:Florida Sales Tax (6%) on rental stays of six months or less. 

Your current situation with your properties is proof of the benefits of long term buy and hold in real estate. 

Operate virtually by building a tight buy box for your end buyers, a basic lead form, and a proof‑of‑work log (photos, timestamps, owner contact confirmation).

Investors want proof you can actually close, and lenders want to see you’re bringing them serious borrowers.

Include your timeline, criteria, and the fact that you're willing to share pre-approval or proof of funds.Lastly, when you speak with the agents, demonstrate what you know about your target market OR what you need help with.

Since they've refused to send over the reports and proof, I was thinking of disputing the charges with Chase. 

One system, clear cadence, proof-in-photos.

(reiterates seller's urgency)It is possible that the seller/seller's agent will refuse to answer some or all of these questions until you prove yourself a serious investors by sharing pre-approval/proof of funds and/or an offer.It is also possible that from just 1 or 2 of the questions above, the seller/seller's agent will begin disclosing additional information i.e. motivation, flexibility on price, openness to different terms, target net proceeds (aka what they want to walk away with at closing)All the best!

And btw, any lawyer can sue you if they wanted so don’t think you’re bullet proof with an LLC.
