It also means you should not have submitted an offer until you had these documents and of course have read them.You would have also received and Addendum to the Contract - Comprehensive Rider To The Residential Contract For Sale And Purchase - Part A of the disclosure states: IF THE DISCLOSURE SUMMARY REQUIRED BY SECTION 720.401, FLORIDA STATUTES, HAS NOT BEEN PROVIDED TO THE PROSPECTIVE PURCHASER BEFORE EXECUTING THIS CONTRACT FOR SALE, THIS CONTRACT IS VOIDABLE BY THE BUYER BY DELIVERING TO THE SELLER OR SELLER'S AGENT OR REPRESENTATIVE WRITTEN NOTICE OF THE BUYER'S INTENTION TO CANCEL WITHIN 3 DAYS AFTER RECEIPT OF THE DISCLOSURE SUMMARY OR PRIOR TO CLOSING, WHICHEVER OCCURS FIRST. 

I just moved and received a piece of mail for insurance coverage for just such an occasion.

Any recommendations on which companies and what type of service or coverage I should target? 

😂We use a one page contract for all of our deals.They're both comprehensive and easy to explain to homeowners.Even with a one page contract though, as @Eric H. said, it's important to actually know and understand what's in it.

Even if you are able to self insure for the replacement cost of the dwelling you should always remember that your liability exposure is limitless so for the liability reason alone you should always insure and have enough liability coverage on the policy and an umbrella policy to be safe. 

Sort of a parable about how to think about money.The 4 Hour Workweek—some nonsense, but also some good strategies for being efficient with your time.The Millionaire Real Estate Investor—really comprehensive look at the path to building wealth in real estate.

Is there any particular topic you'd like to see get more or better coverage?

@Jerry About 2 years ago I went through an identical scenario with one of my condo units.The short story is it depends on your bylaws and the circumstances.In my case, my coverage and the HOA coverage happened to be with the same company. 

Once that's done, do I still need the houses to have landlord insurance or is there other coverage i need?

@Marvin Santiago 2 options, depending on how the property is titled.1)  If the property is in your personal name, your least expensive/best coverage option would be to write a Homeowners policy on the property you will occupy, with the 2nd building as a rental.
