About 15 years ago I worked for an Estate Agency. We had a very large, but very run down house on a super desirable road to sell, the old boy who owned it was dead. It was loosely valued at £650,000 even then (London) and was left to a cousin of the deceased. The cousin had had no contact with him and this legacy came as a total surprise.
Loads of interest in the house, loads of offers. But when the survey came back there were SO many issues - woodworm, dry rot, new roof needed, all the things that the EA can't see on a cursory walk round. So the house was down valued by something like £75,000.
The person who won the bidding still wanted to buy but wanted to negotiate over the price (understandably! down valuation by £75,000).
And these greedy old (yes they were elderly) cousins wouldn't budge. So the original buyer pulled out and the house went back on the market and eventually sold a long time later for under £500,000.
No point to my story, sorry OP, other than people can be very weird about inheritance.
