Nope. I live in a modest 3 bed detached that has the mortgage paid off.
I do know a small handful of people who, (around 2011-2014,) sold their house they bought for £30K to £40K in the late 1980s, for £150K to £170K.
Then they took that entire amount (as it was clear profit because their mortgage had been paid off,) and who took out a mortgage of £130K too, to enable them to buy a property in the £280K to £300K range.
This was at the age of 48-52 y.o. They maxed themselves out with the mortgage, and got themselves another 20 years of paying out (when they were mortgage free at 50-ish,) JUST so they could say they live in a big 4 or 5 bed detached newbuild, with a double garage, and 4 toilets/2 bathrooms in a 'better' area than they lived before.
Biggest regret ever for all 4 or 5 of them. Just so they could say they live in a big fancy newbuild, in a 'better' area; they now have a mortgage that takes 40% of their salary, and they will be working (full time) til they're 70.
I imagine a lot of people who 'maxed out' on the mortgage, and upgraded and tied a ball and chain around their neck til they're 70, have regretted it. I can't imagine why you wouldn't. Getting yourself tied down for another 20 to 25 years, when you were mortgage free at 48, and living a perfectly decent property, in a perfectly decent area before is batshit IMO!
