They're more of a wall street structure and no deed or title insurance is given. 

Does anyone have a document or notice that they have used before about reminding the tenant the end of the lease and stating that landlord/homeowner does not wish to continue or extend with a new lease?

For things like property taxes and insurance I took it from either the county website or a mortgage calculator.It is also worth noting that this would be for a commercial loan (e.g. 5-year balloon loan), but the amortization would likely be 30 years. 

- Any tips/suggestions on what type of insurance to buy for a Condo and the level of insurance needed?

Make sure you run your numbers right including ongoing repairs, insurance etc. 

The down payment/overall price, insurance, taxes, etc seem much lower and the ROI looks to be the same, if not higher on the SFH.

Do you prefer getting an LLC for your property or to use an Umbrella insurance?

I'm looking for insurance guidance.

You have to be very clear with your Landlord, get it in writing, ensure the home is zoned for short-term rentals, and get the property insured properly.

In the decent parts of Miami homes are listed around 250+ with another 10k for taxes and insurance.
