It is still overpriced, even for Topsham, with parking. It's still at least £200K over what it should be in that condition, probably more.
There have been a lot of people from London moving to the area and paying some of these crazy prices. I think they may reduce a bit now that working from home is not such a thing. Buyers in this area wanting 3-bedroom houses are in competition with buy to let for holiday lets and also with older people downsizing from 5/6 bedroom houses who are also cash buyers. The sellers probably think it's worth a try!
It's a nice area and the primary school is OK but not massively oversubscribed (yet- there are hundreds of newbuilds being built on fields all around Topsham!), but there are major problems when kids get to high school age as it's not really in any particular catchment and some of the potential schools are not great at the moment.
