Demolition During IRS's 120 Day Right of Redemption

[Soo Y.]

Based on what I've read here on BiggerPockets, it seems that the IRS's 120 day right of redemption period is merely a statutory right that the agency has not/does not actually exercise(d).

Would it even help me as a 3rd purchaser of a property at a sheriff's sale to start the demolition phase of construction during this 120 day redemption period?  This is because the demolition would actually reduce the value of the property and likelihood that the IRS will redeem.  In the event the IRS actually redeems, I understand I would be out the demolition money but that would be acceptable to me.

Ultimately, the question is could one be liable to the Treasury for reducing the value of property that one owns but where the property still subject to IRS's right of redemption?
