I agree with @Mike Hepburn a bit with his observations.

I am going to my first auction to observe this week but I wanted to do some research on properties being auctioned that day before I got there.

Also have the observation that the area is slowly improving due to many hoses are getting rehabbed or new are getting constructed. 

The auctions are open to the public, you should definitely come down at least to observe. 

I have also observed that most duplex/triplex properties in DEN are sold as Bill suggests.

I was simply making an observation and Josh if I have offended you I am sorry I was simply trying to provide reasons why people may lurk.

There isn't a big "You're my competition so I'm going to try to steer you wrong" attitude.Action is better than observation....

@Ida Saidkariev @Hal Thompson  Very insightful observations and perspective!

We're still learning here, but that's just what we've observed so far. 

If you do decide to invest with what seems like a trustworthy sponsor the best way to do so is to start with a small amount of capital, observe performance, reporting, etc. and then increase your contribution on the next deal.
