FIrst off, WHAT property are you talking about? There was no link with your question
Second, as Chris said, some home sellers are not very flexible with their showing times, the house may not even be ready to show even if listed in the MLS (delayed showing), etc., etc.
Third, who says every house should have, or will have, stainless appliances? Last I saw they still make appliances in other colors other than stainless. If something so trivial is a deal killer for you, maybe you should keep in mind this phrase " buy what you can't change (like layout and location) and change what you can".
As far as the stainless appliances - not sure where to go with that one. What a property has to offer is what it has to offer. Appliances surely have value, but they are an element that you can easily change after you purchase if not to your liking.
Good luck to you,
