in dealing with my brothers estate, we have obtained a formal surveyors valuation from a reliable well established company for £650,000. the solicitor then said 3 valuations are needed and we got 2 estate agents in for a 'time of death' market appraisal, who gave figures of £675,000 and £700,000,one saying he wouldn't go lower so he didn't get any calls from HMRC-I feel they have given higher prices precisely to cover their backs and to try to get us to have the flat marketed by them in future-the solicitor says we have to use the highest figure, not the formal report, which is going to have a big effect on IHT. the idea of having to get more estate agents in feels like a waste of time and stress.can we just submit the surveyors valuation?
