Colorado Pre Foreclosures

[Daniel Haberkost]

I'm looking to approach owners in pre foreclosure through a combination of mailers and door knocking, specifically in El Paso & Pueblo County. I recently had a lawyer tell me that I'm free to do so and that there aren't any specific laws that I need to be aware of when contacting owners. However, I seem to remember reading something to the contrary several years ago so I'd like a second opinion. 

Does anyone here locally have expertise on the topic? Any insight is greatly appreciated!
