Beyond that Huntsville lies in what's called the Tennessee Valley, and in this area of it the Native Americans named it Death Valley due to springtime when the pollen gets trapped within it and coats absolutely everything, lakes turn yellow, and so do cars.

Again, have it all there so the plumber can install in one shot.Paint the walls a fresh, neutral coat.

Do I need one coat or two on the exterior? 

Skim coat a smooth texture and paint it trim color maybe?

But if it is not leaking nor badly damaged, you can always just touch it up with a finish coat and have it look good again.

Valspar oil-based floor & utility paint works great on beaten up hardwood floors and is under $20 a gallon and covers in one coat.

You could suggest the idea by staging it with a standing coat rack and maybe a shoe organizer.

I have about 25 units in SE MI in that price range and my first choice is to refinish hardwood if available, and give it 3-4 coats of poly.

However, get higher quality laminate that is thicker than cheap laminate.

It's probably better to pay at least $0.89/sqft and get the thicker 10-12mm laminate which seems to hold up better to water.
