Compare that to the horrors of older buildings where if you discover something post purchase you didn’t before and you’re out of luck.
There’s bad new builds and bad older buildings too. Both have pros and cons to consider.
A good survey should pick up serious issues though and the rest is up to you to check with your eyes or get someone else in to look at. When I talk about buying a new build, I don't mean one from 5-10 years ago, I mean, buying a new build that hasn't been finished yet.
But you are sort of making out that every old house that isn't a new build was built perfectly.
Everything was a new build once, and there are no doubt loads of really awfully built older houses too.
I agree that you have to accept that even though it's new, it won't be perfect and you'll still have issues just like any property.
However you can at least get them fixed for free on a new build.
No, plenty of older houses were built poorly too but if you get a **** developer you will have an absolute nightmare.
