Valuations...how confusing

Well, we've now had 3 valuations of our house by local estate agents. And it's so confusing, as the 3 valuations differ by about £70,000!

I do wonder how 3 estate agents, all supposedly experts in the property market, can be so wildly different in their views. It's not like the difference between £1 million and £1.07 million. Then I could understand it. £70,000 is a large proportion of the asking price for us and now we're really confused how much the house is really worth. Looking at the market, I think we probably fall somewhere between the middle and the top of the range we have got, but it's so hard to be sure.

So, just for good measure, we're getting a fourth valuation done to see if we can settle on a good average. We need to get selling and quick!
