My question is, should I shell out the extra money for all-new stainless steel appliances, or just clean off the white stove/hood, and save $600-800 by only buying a new white fridge + dishwasher?

Being a house hack, if you break even you're doing fine, just as long as your putting money away (literally, keep it in a separate business checking/savings account) for Reserves: maintenance, capital expenditures (roof, fridge, hot water tank, etc). #4 Agree with DerekI would strongly encourage you to do this if you can, even if it means that you and your folks have to have the house empty for a few months to wait until you and your roommates move in.

I have a 1000 sqft condo in Delaware with a fridge, dishwasher, microwave, stove, washer, dryer, water heater, furnace, and AC unit.

Upon moving in my fridge, garbage disposal, and AC all broke.

The property is set up where the basement has a full bath, full bedroom and a sofa bed along with a kitchinette that has a stove, mini fridge and microwave.

Example, you'd get a house with a fridge and stove but you'd have to buy inflatable matresses and wash your clothes at a laundromat.Those 4-5 other people are out of the STR business now. 

Am I responsible to purchase a fridge for them?

If this used cabinet set came with corners I'd probably pull the trigger and just sand/repaint them, however I just matched up the measurements of the current cabinets and they are... odd:Above the fridge: 33" (+3 inches for the frame, so 36) x 15", to the left of that - a 48" (and not 2 24s nailed together, this thing is huge) x 30", blind corner, then 24" x 30", sink, then 21" x 30", above stove is 30" (+3 inches for the frame) width.

It is a pretty old fridge the needs a valve replaced inside the fridge.

After the appliance arrived I called them and complained (I was told to do so by the CS guy I had spoken with when they called me to tell me of the delay) and they sent me a $150 electronic gift card on a $500-something dollar fridge.
