ie ducting, registers, and all of that?

Sunriver is very picky about colors and styles, they want "natural" and it needs to fit in with existing homes, etc. which all have some variation of siding, windows have to be beige or gray, etc.

Trying to find some inspiration for colors and design.

Make sure your primer color is somewhat close to your paint color.

Personally, I would just replace the counter top and add a little bit of color to the kitchen.

I would rather not have 2 coats of primer and 2 coats of paint to go over dark purple and greens, I had a painter mention there is a paint out that truly does cover in one coat with these dark colors.  

Or is only difference color scheme?

However, I would pass along some advice to the tenant, put some duct tape over that girls mouth, and have her file the police report against the 3 kids. 

pre-owned corian which has a seam at the sink we were never able to blend-experiment but now that floor and decor has granite slabs so cheap I won't buy used corian (color was not the best off white I discovered after purchase too :-( )  Bath 30" vanity got pulled out to add a pony wall?

I have seen some pretty crappy workmanship from other rehabbers, poor design, poor color choices, not fixing bad layouts, etc and they just don't get the same pricing they could have from doing it better.
