Hey @Brent Coombs Auctions are by far my favorite way of finding high quality cash buyers.

Two local vendors below also might be able to get you square away inexpensively but I haven't used them so they are for you to research. call them up and ask for quotes on your desired appliances type and size and colors for scratch and dent.

He's already shown his colors.

The idea of someone not buying a home because the paint color was wrong just got under his skin.  

I would approve of the new carpet, blinds and colors before the work is started.

SanAntonio is probably my favorite place to go.  

Why don't you give a few of the local retailers a call and ask to see if they have any used fridges for the dimensions/ color you are looking for?

My favorite multi-family buildings are the Mathews Flats in the Ridgewood North and South Historic Districts. 

(Uhaul for $19.99 a day)Another option I would consider is selling it for $22-25k on craigslist (People can finance vehicles even if they're purchased off Craigslist, so it's a good possibility they can come up with that money) - and then turn around and buy a fuel efficient truck, such as the Toyota Tacoma (My favorite are the early 2000's which can be had for under 10k)Ignore the future family concern for now.
