I thought a receiver had to get the best price reasonably attainable, at the time of sale, for every distressed property ( their equitable duty to the debtor ). If a receiver allowed valuers to conduct drive by valuations, are they not leaving themselves very exposed to legal challenge. For example the valuer values a house as a three bed during a drive by valuation, but it is in fact a 4 bed with an attic conversion. The house is subsequently sold as part of a large portfolio to a fund for x amount when in fact the market value for the house is substantially more.
