It's likely they bought the house from the home builder e.g. something like Toll Brothers. So the alternative is to take their hundreds of thousands of dollars and buy another house.

Once again, this isn't a pack of oreos you're buying from the supermarket and asking to swap a vanilla in the pack.

Negotiating details is perfectly reasonable at this price point. Swap out the oven or I don't buy the house. This is a case of accepting no and then paying for the privilege.

>Once again, this isn't a pack of oreos you're buying from the supermarket and asking to swap a vanilla in the pack.

That's actually the perfect analogy.

>Negotiating details is perfectly reasonable at this price point.

There is no negotiation possible. It's take it or leave it. Toll Brothers don't care if you walk away; they'll turn around and sell it to someone else.

>Swap out the oven or I don't buy the house.

Right, exactly. Except if you insist on this then the result is you don't buy the house 100% of the time. There's no negotiation.

Appliances are not that expensive, and you are free to sell whatever is in your home and buy what you'd like. If you're getting a good deal on the home you can break even, if not ahead on that.
