How do you choose your "subject" property for comps when just starting out?

[Jordan Sizelove]

Hi everyone! 

I'm just starting out in REI and can't seem to figure out how to properly do a comp in my area (Antioch, CA). How did some of you choose your "subject" property when first starting out? Did you just choose any listing and make it your subject property?

Since I'm fairly new, I don't know what a good price or good deal is in my area. How do you learn this when starting out? I feel like this is the only thing holding me back from getting started.

I've been reading the book on flipping houses by @J Scott  He provides a great overview, but my market is a lot different. If some of you could chime in and share your experiences, that would be greatly appreciated!
