It would be great if people would accept an update once a fortnight, or even once a week. But many want an update daily, sometimes twice daily, even when given timescales such as that their local search won't be back for 3 weeks.
If I email a client to say I've had their replies to enquiries, and I'll let them know when I've had the opportunity to review them, the first thing they'll ask is whether they're ok and can we exchange now. I then have to go back and say that I've not had the chance to review them (as per previous email), it will likely take a couple of hours to do that and draft a report, and I'd expect to get back to them in 2-4 days.
The most urgent things are always dealt with first and that will always be things that have exchanged and are about to complete, followed by things that are about ready to exchange. If I've got 6 or 7 exchanges/completions in a day, I won't have time to do much else, especially as we are short staffed at the moment and lenders are being a nightmare releasing funds. I certainly won't have time to spend 2 hours reviewing a contract pack or lease or checking replies to enquiries and drafting a title/contract report. So it gets pushed to the next day, when I've had another 200 emails and have got more completions/exchanges to get done.
If people paid proper fees for the amount of expertise and knowledge that goes into a property transaction, conveyancers wouldn't need to take on so many files to make it profitable.
It's all very well paying £300 for your conveyancing fees but if something goes wrong they won't be able to sort it out. It will be left to the actual property lawyers acting for someone else in the chain who will end up sorting it all out. Meanwhile, nothing gets done on their other files that day because they spend a whole day (or more) trying to sort the issue out.
