Apartment Hunting Best Practices

Anyone out there hunting for apartments/single family rentals? Do you care to share your experience? I often hear from people looking for residential rentals, so I’m on a constant search for tools/resources for them. We do find a few rental listings in the MLS (more commonly high-end rental listings). Here are a few other options, but…since I don’t use them myself, I don’t know how good they are. Anyone care to share their best practices in apartment hunting?
