We had 2 estate agents round today to value our property to sell (6 bed semi in Surrey) and have had a massive difference in value. The first said £775-£795k and the other said £900-£950k. Feeling confused and wondering whether I need a third agent round or go mid value. I think the bigger value is too high, but admittedly our property is hard to value due to lots of period features and it being unusual for the area. What would you do?
