I'd also look into...
Kensington - 'The Annex' (under construction), 'The Kensington', 'Lido', 'Pixel'
Bridgeland - 'Radius', 'Bridgeland Crossings'
East Village - 'First', 'Evolution', Verve' (very recently completed)
Beltline - 'The Guardians', '6th and 10th', 'Mark on Tenth', 'Smith', Nude (in sales [35% sold])
Downtown - 'Waterfront Parkside', 'Avenue', 'Vogue'
We've got an enormous inventory of central new-build condos with lots of units unsold, so you could probably get a pretty dang good deal, especially on one of the buildings that has been around a few years and still not sold out. Also, there aren't really any sketchy areas in the core areas to be honest, really the only one I can think of is 7th Avenue at 8th Street (an area colloquially known as "CrackMacs") and even then, the sketchiness is confined to the strip mall with the Circle K and the McDonalds.
