Hello,My wife recently got her Colorado real estate broker license, partially to help with our investing, and also to try and earn some extra money. 

Most of your serious contractors wont pay the extra for Lowes and HD delivery.

I recently have been doing some research on different ways to earn passive income though REI. 

The contractor generally gives you a firm price for a finished job , contractor will charge extra for rotten wood replacement .

Are there any brokers, investors or agents in Florida looking for an extra free hand to help assist with anything?

You will need an active real estate license if you'd like to earn yourself a commission on the purchase of your properties, that is if a commission is offered. 

Just make extra payments on your mtg with the same Extra money you would pay back your heloc with.

Maybe market it as you be willing to let tenants rent extra room on Airbnb?

I've been investing on some small businesses (3 of small internet cafe) that earns me some passive income but I want to take my investing lessons on a higher level. 

Obviously, even just based on the 2015 data, the price + taxes (not including renovations needed, etc.) make this property impossible to cash flow if the town ever clamped down on the extra 4 illegal units.
