That's what I do every time one of those "we buy houses" places calls. I tell them sure it's for sale. The price is $4.3 million. They say "be reasonable". I just laugh and tell them they know the price if they want to buy it.If the price is high enough everything is for sale.
If your house is worth say $250,000 and somebody offered you a Billion for it I am sure you would sell it, you would be stupid not to.
