Does this mean there are no home sales?
Don't be ridiculous.

Real estate laws do not require the property to be sold to the first person who makes an offer - or ANY person who makes an offer, for that matter.

If the seller doesn't like your offer, s/he may reject it. Until you have an actual contract in your hands, which you and the seller have both signed, you're not the "buyer", you're just someone who wants the property.
