We have put in an offer to buy 3 different homes over the past 2 weeks, at 3 different agents. Each one, we haven't heard a thing, and when we've called a day or so later, been told the agent was off sick, and then the house has now been sold! Is the 'he was off sick' a common thing for estate agents or is there any requirement for them to offer us a counter offer? I read that agents legally need to inform the vendor of ALL offers, but is there anything in place for those of us trying to buy?
