Why would a vendor put their prices up and down so often?

[flow4]

I've just come across a property that has been on the market since last August. Its price has gone up and down like a yo-yo, usually by tiny amounts:
£159,945 < 0.1% Reduced Sep 2012
£159,950 < 0.1% Increased Nov 2012
£154,950 3.1% Reduced on Nov 2012
£154,995 < 0.1% Increased Feb 2013
£154,950 < 0.1% Reduced Feb 2013
£154,945 < 0.1% Reduced Mar 2013
£154,950 < 0.1% Increased Apr 2013

Has anyone got any idea what this is about?! Is there some sensible possible reason, or is it the sign of a real nightmare of a seller?!

Some internet property searches and email alert search prefferences have criterea like revised price, newest listed etc. if you revise the price you get spammed out more frequently to those with searches in your area.

I would assume the agent would do this do trigger price change alerts on the property websites. I think they might if come up as a 'new property' email when the price changes?

Ahhh. Thanks Mis, I guess that might be it. I haven't come across any other house that has taken it to this extreme tho'! I did wonder whether it was a trick of this particular EA (one of the smaller ones) but it seems not...

X post with you lamb :) I checked the other properties being sold by this EA: this is the only one doing this, so it's probably the vendor's decision rather than the EA. It seems a bit deranged over-enthusiastic to me!
