The Estate Agent is just a facilitator as far as I'm concerned, I've never noticed any either male or female employees that I would have deemed scruffy.
The agents that sold our last house annoyed me on two counts, nothing to do with their clothes. Firstly I had to get them to rewrite the spec several times. It occurred to me I should have done it myself and got them to copy what I'd written, "but then again what am I paying them for" thought I at the time. . They left out some salient facts which I wanted included, such as state infant, junior and senior school a mere five minute walk away, similarly the same for the station, 30 minute journey to London, nearby very largish town a 15 minute walk with great shops including John Lewis, Marks, riverside restaurants. Lovely local high street 20 minutes walk, or 5 minute drive, nearby Royal Park. It's as if they assumed every prospective purchaser was local and would know all that, which of course that's often not the case and "please can you take some photos of the communal grounds that lead down to the Thames" which they hummed and hahed about, "we only take 7 photos, we find those are enough" was their standard riposte. Then without notifying us they also advertised our house with their sister company which specialised in homes with river settings. We didn't even know they were an associated company, we just saw our house on Right Move with, what we thought at the time, was a separate agency whom we hadn't instructed. In the end, they achieved the asking price but not without a kick up the proverbial.
As for the house we bought the vendors showed us around, in our previous neck of the woods, the estate agents want their sellers to disappear somewhere. The vendor gave us some invaluable information such as the local GP Village Health Centre were somewhat under subscribed.
