We had our house valued last week out of interest. Might move if we see something we like. I've kept an eye on prices where we live for some time as well as doing some research on Nationwide House price thingy, Zoopla etc. We've been here a long time and had a valuation about 7 years ago, by the same EA, and the value was what I'd expect. They are a reputable EA (as much as the b...s can be) and the guy who came lives in the same village so ought to know his stuff.
Anyhoo- our neighbours are just putting their house on the market and for 35% less than ours was valued at. I was horrified (so were they but they want a quick sale.)
They have a smaller garden , slightly different position, (we are in a small cul de sac) and our is the better house in terms of position and possibly improvements. However, there is a difference in price of over £120K. I feel a bit gutted because if we do try to sell, buyers will wonder why ours is so much more than the one that will- presumably- sell very quickly at such a low price.
Would you query it with the agent?
