Buying in an "A" neighborhood vs "C" neighborhood

[Alex Silang]

 I currently own 1 "C" neighborhood and have had great success over the past 7 years. Keep rent a little bit below market and keep the property maintained and you can get great responsible tenants. 

I'm weighing on buying a "A" property though. 

1) I heard that section 8 in a way offers downside protection for land lords.  In a recession, you can just fill your property with section 8. Thoughts?

Any other thoughts?
