I have spoken to the agents and they say they prefer to pitch low and get a bit of a bidding war going.
After the FDR I felt a bit railroaded to get the house on the market asap. The house agents called me the day after (on the instructions of my ex) and I was made to feel we should go forward swifty. My ex still has to produce some financial information.
Meantime, now I can think more clearly I feel we should have checked with the other two house agents we originally asked for estimates to make sure the price was on track.
