Our house is an easy sell in a nice part of SW London near good schools etc. Lots of young couples settle around here to start a family, often moving from inner-London boroughs where prices are higher, and often introduced to the area by estate agents. There are lots of local estate agencies, but we're tempted by Dexters who operate over a wider area and so have more of those types of potential buyers on their books. They sell a lot of properties around here.
Websites like this one tell me I should be trying to negotiate fees down to 1% or lower, but would I be whistling in the wind with a pan-London agency? It would be handy to know what's achievable, but it's not something that seems to get discussed on the review sites - perhaps they make you sign a non-disclosure agreement before they'll agree to lower their fee!??
