If only there were a more scientific, predictable way of valuing houses rather than the stick-finger-in air method, house buying/selling would be somewhat eased as everyone concerned would have a better idea of the true worth of a property without continually having to factor in wriggle room for estate agents' or vendors' wild optimism.
How about:
Location - quiet/noisy road (score 10 for quiet, 5 for noisy) Floor (i.e. living) space in cubic feet (cubic to factor in room height) Garden size(s) With/without garage Condition: Wreck/habitable/pristine
...and so on. A list like this would be a doddle to computerise and even make available on the web so that an agent on site could connect to his or her office via pocket or laptop PC. The scores would be totalled, and a *ballpark* figure arrived at. Over time, individual scores could be adjusted to fine tune the ballpark.
Finally, the agent could hand the vendor a printout showing a complete record of how the ballpark valuation was arrived at. The vendor would be able to wave this at prospective buyers to demonstrate that the asking price arrived at is reasonable. If a greedy vendor asked too high a price, the buyer might ask to see the printout of the ballpark valuation. If (a) there were none, or (b) the vendor did not want the buyer to see it, well the conclusion is obvious as vendor watches buyer hightailin' it down the garden path.
