Yes, why the secrecy?
When calling the estate agents “move managers” they should be able to say exactly what is going on, what problems there are and the timescales.
Actually, shouldn’t have to call and chase them, there should be an app which shows the chain and the progress of each with updates. So you can see, for example, house two in the chain is waiting for searches back, house 4 is waiting for valuation etc.
The lies, half truths and constant secrecy and not getting answers is what makes the process so stressful and there is no need.
