To be honest, it doesn't sound like you want to, and doing things just for the money never bodes well.
I'm single and live in the suburbs on London, however it really works for me. It's significantly cheaper, I give you that, but it's not my motivating factor. I love quiet. Yes, I like to sit at home and hear nothing, and absolutely adore hearing the birdsong on my street on the mornings. I also love gardening, and have a 100 ft garden that I grow loads of veg in. And my commute is a walk to a station, then 35 mins of train, where I always get a choice of seats, that I use as my reading time. I also love having space at home, having a lounge and dining room, a spare bedroom and a kitchen I love - complete with aga. It's such a good place to cook and have people over.
So for me, the suburbs work. Don't get me wrong, I love visiting the city and working there, and the commute home does get a bit tiring for me, even though I love where I live. If you weren't vested in it, it would get tiring quickly.
