Indeed.
We've sold cars to those car buyer outfits and people say "you sold it too cheap" so these days we dont tell them - we sold to the outfits as it was easier and no comeback and not a great deal of difference as we'd more than make up for the slightly less price when buying another brand new car ie no p/x.
Property is difficult to value if it is on a road/close like ours where there are several different variations of houses eg, detached, semi, a row of terraced four houses and a few detached and semi bungalows and garden sizes and drive sizes along with property size varies.
If anyone is selling, get a valuation from 3 EA's - they only get money when the property is sold so some will try to convince you to a lower price and another to get your business will initially place an unrealistic higher price to get your business and then lower it quickly with your consent.
As I said, it is only worth what someone else is prepared to pay. Often cash buyers, ready to go people will want to pay less and those in chains pay more but you know what happens to chains at times.
The biggest problem I've seen is when a property is owned jointly people divorce or want their share to move out and one half feels the value should be higher and other says lower if they want to by
Re EA's - I've met several nice EA's, IE nice when you are selling/buying but once the exchange of contracts is signed they have a personality transformation, lol.
