We bought our first home last year and I felt like this - from the moment we walked in on completion day I knew we’d made a terrible, terrible mistake. The stress and pressure of it was awful, it’s not like a rental where you can just choose not to renew.
I had a thread on here and got responses from two clear camps - people who said buyers remorse was totally normal (but this was beyond what was normal) and people who’d experienced similar.
Posters told me we couldn’t sell within the first year or two as people would be suspicious. I’m glad I didn’t believe them…
6 months after completion (the amount of time most mortgage lenders want a house to be owned before they’ll lend to a buyer on it, because of money laundering regs) we got some estate agents round to value and put it on the market just to see what happened as no cost to us if it didn’t sell.
We sold in a week, to the very first person who viewed, and had about four other viewings in that time despite the slow market. We accepted slightly less than what we paid, but we’ve also paid less for our new house.
I’ve felt no buyers remorse at all since we moved. Sure we’ve found problems and things we didn’t notice, but I feel so different about them than I did in the other house. I’m glad I ignored the people who said the way I felt was normal (it wasn’t) and that buyers would be too suspicious (they weren’t). Your wrong house will be right for someone else, when the time is right for you.
In the meantime, be kind to yourself. I found this a very lonely experience - it’s hard to confide in others because ‘I bought the wrong house’ sounds like first world problems, but personally it caused a serious relapse of depression for me and at the time it felt insurmountable. So take care, whatever you do or don’t do.
