Sorry, but I can't blaim them. Firstly you don't know what condition the interior is in, there could also be other factors for the property reducing it value.
It also be that their timescale has quickened and they really need a quick sale.

Also, when making such an important step as selling your house, you can't afford altruism too much.

It is a bummer.
When we bought ours, we paid 147K, then found out one that was the ssame but with an extended kitchen and conservatory sold a couple of months later for 127K we felt gutted, however 18 months later we have accepted an offer of 147K. So there obviously were serious differences between the properties and we had not paid over the odds.
