As for repairs, you can ask but their standard answer is the property is sold 'as is'. They may make repairs if it's discovered to be a safety issue - but there's no guarantee. All you can do is ask.
As for appliances, with the purchase of most if not all foreclosed homes the lender/owner will refuse to sign any personal property agreement which is where any existing appliances would be listed. As far as they're concerned if the the appliances are working and in the house on the day of closing, then they are considered a gift. Otherwise they will make no guarantee about appliances being in the house on closing day nor would they buy appliances.
If you need cheap appliances, consider Craigslist.org.
