What I like to do is scope out the area by meeting renters within a complex I'm interested in. Just did this a couple weeks ago. (I'd like to buy a unit to rent out, not an entire building for living in.) Find a single parent, someone whose every buck counts, and strike up conversation. Make them feel like they can relate to you and want to help you. I don't lie but if they are unskilled in asking questions, I'll let them believe I am just like them i.e. mom on her own with 2 little boys who requires a good value in renting a condo. I try to zero in on renters in particular. Owners are too prideful for an honest discussion - keep walking. For the renters, I ask what their landlord is like. How are the neighbors. They tell me any problems going on with the HOA or community policies that are problematic for them. I just met a lady (single mom, renting, lived in this complex for years and years) who was extremely helpful. She gave me a tour. If there's an issue with fines for this, that, and the other, they'll tell you. Even things I never thought to ask. Pests - ditto. I'll ask if they have any beef with their landlord, etc. They are using this person's name today but may be using yours tomorrow. See what the general attitude is.
Leave your Benz at home. Take your oldest car or have someone drop you off. Try not to be pretentious. You want to get the good stuff out of them.
