I bought my house on the basis that it was a house I wanted to live in, in a place I liked – great for biking, climbing etc and has shops selling beer, cake, chocolate – and was within my range of affordability.
Ultimately you’re buying somewhere to live, you can agonise over the possible ups and downs of the housing market etc, but the baseline is that unless you view your life as a series of investment opportunities – which is why the country is going to hell in a handcart fwiw – you’re actually buying a home, somewhere to live.
What’s ‘affordable’ for you is one of those fluid things which depends a bit on your job stability, employability and how big a mortgage you feel is tolerable – I’d rather not have to pay out so much that I’m effectively locked into a particular high-earning job – I wish…
I blame Thatcherism for turning home-ownership into some sort of investment game/status wankfest. And if you can afford to buy a flat in London you could probably land a five-bedroom detached farmhouse with a whole barn to store your bikes in up here… 😉
