Sometimes it's good to know that there is nothing wrong, it just wasn't for that particular viewer, indicates that they had an unreasonable expectation for the area. It might even indicate that the EAs are just pushing people to view so that they appear to be fulfilling your expectations as a seller. I've had all of these . . .
Selling one place, a bungalow in an area popular with families. Our particular bungalow had steps up to the front door, the first person who came to look wanted a huge reduction because he was buying it for his mother and would need to make mobility adjustments. "No, it's the wrong bungalow for you." Sold to the second, who loved everything about it.
Another, in an area with a 'local vernacular' of workman's cottages - small and quaint, with an emphasis on the very small, but actually very sort-after, with a price to match. Several viewings by people from out of area saying it was too expensive and there was no where for a dining table. Sold within a month to people who knew the local market.
Buying our current house - four bed detached in a particular price bracket - EA persuaded us to also visit a three bed at the bottom of our price range, new to market. It was tiny (esp in relation to the one we wanted to see -and bought), semi-detached and had no garden. Our feedback was that it was lovely, but not what we had been looking for or led to expect.
In each case, it was good to have a reason that wasn't just "the place is a mess and you need to sort it out!
