Nothing in here that any good agent won't have told you, or a mediocre one hasn't preached on his blog for years, but it's a useful summary from Britain

but i wanna get that much! I wanna!

Seven things that won’t determine a home’s value

1) What you paid for it

2) What you need

3) What your neighbour is asking for their house

4) What your friends say

5) What estate agents say (This one deserves full text)

Estate agents will likely be the people most sellers will rely on to give the correct valuation. 

Unfortunately, some agents may be more concerned about winning the instruction, than they are with giving an honest assessment on price.

They'll then spend the next few months blaming the market for the lack of interest and claw the price down.

This is why it's important to audition a number of estate agents for the part. And don't necessarily go with whoever says the home is worth the most, or who says they'll sell for the lowest fee.

'With the market hardening and new business hard to come by, I'm afraid there are some agents who will flatter you with an inflated figure in the hope of getting your business,' says Pryor.

'One of the biggest agents in London only sells one in five of the properties they take on because they are so optimistic in their pricing.' 

6) The cost to rebuild

7) What you've spent on it

I’ll add one more: Sentiment. My family made this mistake, and I’ve seen clients do the same thing. In our case, when it came time to sell our mother’s house on Ole’s Creek, we carried into the estimation of value all of the wonderful evening dinners overlooking the water, the Easter Egg hunts, and the family celebrations of holidays and birthdays. A buyer is looking to build her own memories, of course, and not buy yours, so the fact that your children once played in the tree fort you built for them, or a swing you hung from the old oak tree, means nothing in cold, hard economic terms. But it can be hard to separate those memories from a price appraisal; it happens a lot — in fact, it’s probably the reason so many agents’ own houses are initially overpriced — so guard against it. That’s where a neutral agent can bring objectivity to pricing, and it’s needed.
