As mentioned, an LLP is usually for a professional services company and in Florida, an LLP is required to carry insurance. 

My thoughts: make sure its OK with zoning/HOA, ask your insurance company about liability and any sort of requirements for insurance the tenant would have to have.

I'm looking for a new insurance company in Houston TX - any recommendations?

We have 25 units spread over 19 properties... which means we have 19 property tax payments, 19 loan payments (per month), 19 insurance premiums, etc. 

Get title insurance, presumably.

I'm a little leary to think that 6 nights (3 weeks * 2 nights) is going to be enough to cover mortgage, insurance, property tax, maintenance, cleaning, furnishing, 100% of utilities, cable, internet, etc. but maybe I'm all wrong. 

The way he arranged it might have even included some other mechanisms but I can't remember (life insurance, ira, annuity?)... 

.$3,000 in escrow for taxes and home insurance.Monthly payment will be $1,375 which includes taxes and insurance figured in.The monthly rent is $1,650 so that will leave me a cash flow of $275.To remind everybody this is a SFH that I purchased 2 months ago and should be appraised at around $210,000.

We have it added to all out policies & it's about $20/yr.

If you force a 12 month or move policy, they may take you up on that option and leave.
