So for a 2-story house with a basement unit (combined for a total of 2 units) with a market value of $550,000 that also has 6 parking spots, 3 indoor and 3 outdoor I should be able to collect a total of $5,500 monthly rent? 

The Orlando Paintball location has some indoor warehouse space for two courses, so building a larger warehouse than needed and renting out a portion may work as well.

And I know that as well as store fronts that sell, there are a huge number of indoor grow operations that operate in industrial areas, as we as in residential neighborhoods.

My 1st house had an indoor hot tub in a sauna type room with cedar paneling.

I bought an indoor thermometer from the hardware store and gave it to her.

In over 22 years of landlording, we have never met a smoker who didn't eventually smoke indoors once the weather turned bad, in spite of our no-smoking policy.We impose a $50 fee every time we catch someone smoking on our property (inside or outside) or have sufficient evidence to ferret out a confession.

If you yearn for the "fresh" air of the outdoors, build a gazebo in your backyard and keep you indoor air clean.

@Casey Andersen @David Lavin I assume this is indoor plaster? 

The complex my condo is located in has 3 pools, with one of the pools being indoor. 

I play volleyball 3-4x a week competitively indoor and outdoor and I'm always looking for a new game if you know one in Pittsburgh.
