When we sold our first house 20 years ago we invited 4 estate agents round to get an idea of prices. It was a one bed semi-detached with good links to London so was a popular area.
Three out of the four came in with prices very similar and the fourth came out with a price £20,000 less and she was very pushy and was telling DH that we would never get anything higher and she had a buyer ready - we knew she was dodgy and when we sent her on her way I kept finding her business cards around my house.
We also went away for the weekend so the Estate agents could get lots of viewings in - we were 400 miles away from home and we get a phone call from the EA to ask if we are home as they want us to show someone around, we explained that no we had told them we were away and they had told us they had lots of viewings.
We asked why they were ringing us and not showing themselves as they have a key - it turned out that one of the staff had taken the key home with them and they were not in that day - to say we were not happy is an understatement.
We also agreed to a viewing on a Sunday lunchtime and changed our plans, the couple turned up and the man was only interested in seeing the loft as he was a clockmaker and the EA had told them the loft was big enough, (they had not looked at the loft) you could hardly stand in the loft and it was not even boarded out.
I also showed a gentleman around and he was saying the EA had told him all my bedroom furniture was included - it wasn't but I was willing to sell it to him it cost nearly £3,000 a year earlier.
Our buyer we were told was a cash buyer - we found out they would only be a cash buyer once their house was sold.
We were buying a new build so it was time sensitive and luckily Parents from both side lent us money so we could pay the mortgage off on our old house and release the funds for the new one.
