I just bought end of June and completed beginning of October. I felt the exact same as you. My mum was putting me off buying anything at the start, but then all of a sudden she changed her tune and was nearly forcing me to buy stuff. I was a miserable sod though and even though I tried I couldn’t get excited about it. I thought maybe talking about how excited I was would help but it didn’t.
Even on completion day I wasn’t excited as I had tonsillitis and had to have a COVID test that morning
so my auntie had to go to the estate agents and get my keys for me. In some ways I’m resentful of COVID (even though lockdown is what helped me with my deposit) because I knew I would finally feel that excitement walking into the estate agents and that was taken away from me because I followed public health guidance.
I was finally excited though when I closed my front door to my parents and was finally on my own!
Tip: make sure you check when the boiler was last serviced. I had to shell out £2100 for a new boiler even though it had been ”serviced”
