Yes, I agree, I would fund it hard to replace a 3 year old kitchen that I just didn't like. Seems so wasteful.
It's been a while since I have moved but I have moved house many times in the past 20 years.
Out of nosiness, I like to keep an eye on my previous houses if they ever come on the market again.
One house I sold was a lovely old Victorian terrace. In the 6 years we lived there we updated a lot, but we didn't get around to the bathroom. It was fine, just a bit tired. We also didn't do much to the kitchen but it had been done a few years before we bought it and was fine.
Family bought from us and sold again just 18 months later as they were relocating for work. I could see from Rightmove they had renovated the whole house.
New bathroom and kitchen which would have cost tens of thousands. They looked good. I would have assumed this would add value.
In the other rooms, they had painted and papered and recarpeted. I felt this was very unnecessary as they had almost replaced like with like - mostly neutral wall colours and slightly different coloured carpeting to the (good quality) carpets I had put down just before selling. And the rooms were big and the ceilings were high, so none of this was cheap.
Anyway, they sold for £20k less than they paid us. I really felt for them. This was in 2020.
Anyway, the house has sold another twice since then (not sure why there has been such a high turnover) and each time there has been a brand new kitchen and brand new bathroom. Nothing reconfigured. Just all new cabinetry and appliances. Not even a big change in style. Just "new".
I know everyone deserves to live in a house they love, but i find the wastefulness of it all upsetting.
