I would go for it. It may be a little more expensive, but really it's only $40 for an extra bedroom in a nicer area, although you will have to drive further for DP's work...is he able to catch public transport rather than you having to drive him?

But it definitely sounds a lot nicer than where you are now- would you really feel safe bringing bubs up in that sort of area? Not to mention having an extra bedroom of space!
