I hope this helps-
There is only one condo listed for sale here. (7040 Olive ave 7-- $62,000).
There were 2 recent leases there- one in Jan ($800/mo for a 3 bedroom) and one in April ($695 for a 2 bedroom). They took between 1 and 3 months to lease (this will vary depending on the management company marketing the property)
As far as peaceful- this crime map may show you what crimes are reported in that area : http://www.trulia.com/crime/Glendale,AZ,85302/ As far as i interpret it, it looks like the condos themselves are quiet, but the surrounding area has multiple recent reports of theft. This could happen anywhere.
