It would make a huge difference as the buyer would be paying 3% stamp duty rather that 1%.
£0 - threshold NIL
Threshold - £250,000 1%
£250,001 - £500,000 3%
£500,001 and over (all properties) 4%
£1,000,001 - £2,000,000 (residential) 5%
Over £2m (residential) 7%
OK so I picked a bad figure for my example. I'm not up on UK stamp duty, and anyway you shouldn't think yourselves lucky, it's 8% minimum on everything here!
But my point still stands. Adding the estate agents fee onto what you want will not have any detrimental effect on the interest generated in the property.
