If it doesn't make you feel embarrassed, its not low enough.
Relocation, Relocation last night an offer was made £19k below the asking price think it was on for around £330,000 and was accepted.
As mentioned you never know someones situation. The property is only worth what somebody is willing to pay for it at the end of the day.
Don't take the wee but give them a low offer and see how it pans out. You can always go higher, makes them feel like they've managed to squeeze a bit more out of you.
I'd start at £125K
