I put one in the living room and main bedroom, the basic black Harbor Breeze fans at Lowe's do the job just fine for $60 and look nice. 

I just had a large group check out and our cleaner informed us that while most of it was what you'd expect from a large group, the bunk room had two sets of bloodied sheets, imprints on the black out shades, multiple chalk drawings on the garage floor, various towels used to remove makeup, various dirt handprints on the walls, and didn't run the dishwasher.

We’ve been sanding and painting kitchen cabinets and applying new modern black hardware and new black hinges to make them pop.

The other thing I notice and this goes from East Coast to west coast northern border to southern border is the poor have an affinity for red or black gauze like curtains.

On one of their finds, they told us that they found black mold in the kitchen and bathroom, which is interesting since I painted and redid the faucets in those two areas, and saw none.  

Paint it, remove green weeds and green window cover thing, maybe black top the driveways.

So I picked up a 5lb bag from Black Rifle.

If it's an old wood window that can't be replaced or blocked super easily, you could always go down to the studs from the inside, put a piece of treated plywood (painted black) over the window itself, and screw that into place so that it's flush with the studs.  

black and white looks good . the grays are out 

See those black handle-things on the window?""
