Tax sales are going on right now for Colorado.
they generally have them online and Colorado is a great state for liens. Not because they have high interest (which this year is 10%) but because they have a very high redemption rate.
When you buy a lien in Colorado you are about 98% chance that the owner will redeem the lien within a year! that is awesome for someone that is just looking for a good safe return on money.
The auctions will be online at realauction.com
properties that are not sold will be able to be purchased through the mail after the auction is over.
let me know if you have questions
