Doubt this is putting people off booking a viewing in as I’m not sure why you assume people would be standing outside and looking at your house before booking in a viewing.
Presumably your house is on the various property and the estate agent websites and in their window. Most people I imagine don’t do a drive or walk past before booking in a viewing.
We’ve viewing properties at the moment and while we’ve spotted a few potential houses by chance as we’ve walked or driven past signs on the way to other places, the majority we’ve booked to view were through property websites.
We might then do a quick look at the street on Google Maps but generally we wait until we visit the house to check out the surrounding roads.
Obviously no one really wants to cope with a strange and bouncing dog when viewing a house (I don’t and I love dogs), but you say it won’t be there for the viewings.
How long has it been on? It’s a hard time to sell at the moment. It’s always things like price, location, condition, and competition - if your house is in a similar bracket to other houses but they have something extra, a bigger garden, an extra loo, better condition, closer to amenities, parking, etc. - that drive viewings. Are the photos good?
