But if you are going to go completely by the rules and report land separately, you would need the purchase agreement to break out the cost of the land separately ---------------- something I have never seen.  If it isn't broken out separately, you are doing your own work around to fix the purchase agreement.  I prefer "six".  I have never broken out land on a 4797 and to this day I have never had an armed IRS agent come storming into my office demanding it be broken out.  What's the old saying????? Oh that's right - CAGMC 😬
