Reasonable offer seems pretty self explanatory to me, do you have to follow the sellers request that's up to you but to act like you don't basically know what is meant by it is a little ridiculous. And yes the seller can be out of their mind on asking price but still you basically know what they mean by reasonable offer even if it don't seem reasonable to you.
The problem is the key word "reasonable" and reasonable to the seller is different than the buyer. One reason why "reasonable" doesn't work. Also, we know how unreasonable some people can be. :poke: :rofl:
