As an example for your "demolition" section, I'd figure out how much square feet (SF) of wall needs to be removed and show it on your sheet as $/SF.That way when you're done with the project you can go back to your original estimate and enter in the ACTUAL costs and compare to your estimate. 

There's a large, unused space that's bare bones on the ground floor (as in looks like a basement, concrete floors and walls)  that could be renovated into an extra 1 bedroom unit.  

I like to hang my shelves on a 1x3 that I paint the color of the wall. 

If elevated moisture is present then there could be mold behind the wall where it is visually wet.There is surface mold and air mold.

Before I joined the Army I did home improvement side jobs, i.e. paint, dry wall, tile, carpeting, roofing, little bit of framing, pressure washing, junk removal, lawn care.

My questions are Day to day operations dieing to know what goes on inside the walls are you even required to be in the brokerage so many hours a week as a new agent?

I won't be opening the outside walls, so did he mean putting insulation in the attic? 

I paint my walls all the same color.

well i guess it's normal stuff like cracked sidewalks , retaining walls are leaning a little .

WE PUT OUR BACKS TO WALL AND REALITY HAS SET IN!
