Your mortgage insurance is low also.

Framing, roofs, exterior, plumbing, electric, ect. 

On the side, for the past 12+ years, I've been a hammer-swinger for the two residences I own, doing literally everything except roofing (yep, everything, including plumbing, electrical, ductwork, flooring, demolition, framing, drywall, brick-laying, windows, cabinets...... etc).

Currently, We have our properties insured with REI (NRIEG).  

- Do you purchase federal Flood Insurance for your rentals? 

This would be items like mortgage interest, real estate taxes, home owners insurance, utilities etc.Pro-rating the expenses have to be done in some logical methodology.If the units are of equal size - they should likely be 50% allocated to the personal residence and 50% to the rental property.if they are not equal - you can pro-rate based on amount of rooms or square footage.

as low as 5% down on 2-4 unit, lower mortgage insurance premium and no upfront insurance payment at closing, and it's a conventional loan so stronger offer and less red tape than the FHA. 

If I hire an architect to help design & permits, get the foundation done by a licensed contractor, have Tuff Shed build the shell (they install it too), and if you can hire out subs to finish up the rest like electrical, plumbing, HVAC, flooring etc.. would self managing the project work?

I asked him for his license and insurance and suddenly he shy's away and I don't hear from him. 

And it Florida it is code approved and accepted by insurance.
