Housing gets especially expensive, at least here, once we toss property tax and school tax on to it. New York is really trying to price us in to moving out of state sooner rather than later.
Sadly the error message wasn't the worst problem that app had. No multiple accounts. No use of the Important Message feature. I've heard tags could be accessed by swiping right but that never worked for me and seems t have been an issue for many other users as well. Not to mention the whole app felt like a rushed kludge job of half baked ideas, and very inconsistant user interface. Not to mention it was far slower than just using the web site or Apple's own mail app. I think it needs a lot more work before they bother to resubmit it to the iOS app store.
