The example they give usually is that somebody has no equity and is in foreclosure so they Quit claim a deed to you, Then you contact the IRS to have the lien removed or released as long as you  can show there is no substantial equity.My question is this : Will the IRS work with you as a buyer of a property that has an IRS lien on it if you have NOT been given a deed to it  and don't own it yet?
