We are fairly chain free between the people we are buying from, they wanted to exchange last week and complete last week of Jan. They couldn’t understand why I wasn’t happy to do that. I just felt so much can change in that time, including what condition the house is in? Or is it normal to have such a long period?
~4 weeks isnt a huge amount of time, but it depends really, why the wait? there may be some reason for it but it's hard to say...
When I bought a place (no chain from either party) we exchanged and completed on the same day. If I recall correctly we were supposed to exchange about a week prior, but due to a **** up from the solicitors I was buying from it couldn't happen, so it all happened at once to avoid extending the process, I supsect my solicitors may have given thier solicitors a polite rollocking to move things along.
