Wow, congrats though on building your first house, that is impressive, some day I would love to do that but of course i'm in no position to do that at the moment.
The last few days have been busy. We put in our offer, it was accepted, we went to Natwest on Wednesday and applied for the mortgage. We paid the solicitors on Wednesday and asked them to start searches. Today (Thursday), the valuation has happened but we don't yet know the result, and searches have begun (We had to fill in a huge number of forms). We are aiming for an exchange date of a week tomorrow having asked everyone to communicate via email rather than post where possible and making sure we give everyone everything they need.
We also have a plasterer booked to view on Saturday with us to try to get quotes on how much it will cost to re-plaster a lot of the house.
I'll let you know how it goes!
