Surely you left a massive amount of money on the table then, right?

They may have been better off also. At least the agent commissions are saved, and maybe other costs. If the buyer is motivated to buy, who knows if they weren't already over market?
Big saving all round.
That's my point. You could potentially have made a lot more money on the open market. Especially if the buyers didn't even try to negotiate. That usually means they would pay more (let alone what other buyers might pay).
The value of your house is what people are willing to pay for it, not what you think it's worth or what you want for it.
Of course, most buyers will want to see the house themselves before making an offer, as estate agents are famously creative in their property descriptions. If you're getting a mortgage to buy a house, the bank will generally insist on a 'survey' where an independent third party turns up and confirms that the building physically exists and suchlike.
I bought my house right after it was listed on my realtors MLS system -- I had already made an offer before it ever hit Zillow or before there was a For Sale sign in the yard.
In the UK, it is very much a paperwork exercise, I have never met any of the solicitors I have sold houses with, haven't even spoken to most of them (everything on email)
