S.A.
I moved to Garner from Chicago in January. I actually ended up renting a house instead of an apartment (there are a lot of problems with roaches in apts) and I found it by posting a free ad in the Housing Wanted section of Craigslist.
you (or she) can search for apartments on sites like www.apartmentguide.com, www.rent.com, www.apartments.com --just remember that those complexes provide the info so its biased.
I advise checking out any potential apt neighborhoods by going to www.apartmentratings.com to see what present and former tenants have to say.
