If someone shoots her house, spray paints the siding, throws rocks through the window, drives a car through the house.

@Larisa Van Valkenburg If you are doing your testing with a hose, I would also get of the roof spray water on the roof,  and see if it's coming down behind the gutter, or if the down spout is clogged causing it to overflow and dumping water in the corner, and then not having a place to drain to properly.In the early years we did many multi thousand dollar "fixes by the pros" that didn't work, that we fixed with proper testing and a bit of proper draining.Key is to create a path on the outside to get water to drain away instead of soaking into the ground by the window.

If you're going to paint the cabinets, spray them with oil based and a 2/311 tip.  

Spraying cabinets is great if you take them out to do it, but you'll spend two days just taping everything off if you do them in place.  

In that price range I'd spray the duct with primer and paint to match walls: it will blend in a bit. 

Rust-Oleum has a high-heat spray can paint.
