Tax Liens and Colorado

[Donna Gilbert]

I have been trying to research Colorado tax liens for some time, but for the life of me, still cannot understand them. I've registered with Arapahoe County and, although I know they have their auction in November, they do have County Held certificates available for sale on their site. It appears that you can pick these up for as little as $30 (I can't imagine that these are a good deal) all the way up to $243,000. It looks like almost all of these County Held certificates are for vacant lots (owned by developers?) Does anyone know if these are worthwhile? Any information that anyone can provide would be greatly appreciated!
