In other words, does depreciation recapture add to capital gains, or replace it?

As you have said in your post, you have a six figure income, are you looking to replace/grow your current income?

Both showed up in the city permitting so no issues there.Frame new bedroom in front portion of houseRepurpose laundry room into master bath suiteRepurpose current master bath into master closet and washer/dryer closetEnlarge openings into kitchen and family roomTotal kitchen gutReplace all windowsRelocate front doorAdd front deck and replace back deckAdd central heat/air as the house had window unitsWhen we first walked the property the front room felt like it sloped.

Engineers, architects, etc make things very costly!

I am a 23 year old engineer with a degree in Manufacturing Engineering Technology.

In CA they require 4 years, they do recognize the education, if you have engineering degree or what not, in that case you still have to get 1 year experience in the trade, maybe not really pounding hammers but at least a supervisory level.

The association fixed the problem causing the water to enter the building, but I want my floor replaced!  

That compares very well with the 16 - 25K of tax plus depreciation recapture on a profit of 80K .The real question is can you find good replacements that fit your parameters within the time constraints.

The roof is in need of some repair (~$2000), but should probably be replaced entirely in the 3-5 year range for roughly $21000 (huge roof).

I know in the town where our apartment building is, the above doesn't require a permit, but if I was going to replace windows, then a permit would be required.Also, our electrician told me that licensing is not required to perform any work that isn't going to be closed up behind a wall.
