Colorado Tax Liens - Why bother filing for treasurers deed?

[Nick P.]

So I have been deep diving into Colorado Tax Liens last 4 months.  I understand you can begin the process to receive the treasurers deed at 2.5 years and in theory (excessively unlikely) receive the deed in 3 years time.  I have read all the Colorado statues and annotations, and can't find anything suggesting I can't keep endorsing/let interest accrue past the 3 years time.

So my question is, if your tax lien is a small percentage of property value, why would you bother to start the redemption process and most likely get your capital back?  It seems continuing to endorse/accruing interest would be the approach if I want the interest.  Anyone familiar with any reasons/cases/laws of why this would not make sense?
