I found Yopa very helpful all through the stages of buying ... The problem came on completion where we were going to be left sitting outside my new home for hours 4 to 5 to be exact while the agent was off selling more houses with our keys ... it seemed as soon as it completed we were the last thing on her mind .. she was miles away with a full list of viewings.. The keys are not available until she decided to drive over at end of her day ..had it not been for my daughter driving over to fetch them miles away we would have been on drive for hours.. I would not buy a house with an on line estate agent again ..or sell through them as it would be unfair for the buyers
