She's middle lifestyle, so that option (living on the border of a high-life area) would work. It would certainly appeal to her (as a cultured pixie) more than living in gang territory.
Since being taken in by her foster parents, she's basically lived in corp housing, so she's used to the more secure and presumably "nicer" areas. As a corporate SINner, she could very well still be living in corporate housing even though she isn't actively employed at the moment (I probably should have taken the Day Job NQ instead of Creature of Comfort, but that puts additional burden on the GM to work it into the campaign, otherwise it's not really a NQ, so I opted not to). I haven't really come up with a good way for her to keep her association with NeoNET but still explain her lack of "official" employment - I'm mostly leaning toward "layoff", so she still has the SIN and access to corporate services it provides (living areas, etc - not material resources), but has the free time to pursue Shadowrunning.
If it's too much trouble to have us live in areas outside the four gang areas, it's no problem for her to live in one of them. Her experience with Spanish and/or her general lack of familiarity with the are could explain her living in the Hermanos controlled region. Being largely free of violence, she'd probably hardly care to move if given the opportunity so long as Middle lifestyle housing is available (gotta cater to that CoC NQ...).
