Michael,Situations like this can be a real fight between your emotional and logical sides of your brain over what to do.Here's what my emotional brain would say in that situation:1.

Thanks to all here for the knowledge and insight, and especially to the forum moderators as it's very nice to read post after post of useful and smart answers & information instead of fighting and posturing as on most other forums I don't belong to anymore.

So to fight it, I am jumping head first into my real estate licensing class (access to the MLS) and I should be ready to take my test in about 3 or 4 weeks.

If you have good deals, you'll be fighting them off with a stick.

They appreciate that especially in a market where they dont have alot of work & have to fight for everything they get.

I am very angry but am not sure how far I should go in fighting this guy?

We haven't evicted in CO since we just bought a couple months ago, but I can give you our (limited) experience in CA and AZ:Orange County CA: 3 months (the tenant at first tried to fight it, so that added some time. 

I recently checked out some of the new track homes in Irvine, CA and am very interested in potentially learning more about this area.

That and evictions, it seems like former owners are getting better at fighting us.  

Also with a vacant building no jobs impacts to the  economy.This is generally an easier sell than you want to build on beautiful and open natural wooded areas where you will get fights from the tree huggers and community at large.
