Not sure how much painting you've done, but me and the wife just painted two houses complete exterior for $325 each (not counting a $125 sprayer we already had).
We've painted complete interiors several times for about $250.
So give or take less than 1K to paint entirely to your liking.
WTF don't people get that, and make it a "I can't live there" issue?
I guess it's good for those of us that do get it.
Buy cheap if it needs paint, paint cheap and sell high!
