The Most Common Reasons Exchanges Fail

  1. Taxpayer closes the sale before engaging a QI. Unfixable. Engage the QI first, always.
  2. Taxpayer takes constructive receipt. Funds flowing through any account you control voids the exchange.
  3. Missing the 45-day identification. Start sourcing replacements before listing your sale.
  4. Missing the 180-day closing. Build in buffer; don't trust lenders to be on time.
  5. Using a disqualified person as QI. Your CPA, attorney, or agent can't be your QI.
  6. Buying down (replacement cheaper than sale). Creates taxable boot.
  7. Debt down without offsetting cash. Mortgage boot is the silent tax killer.
When to reach out. Call me before you list your sale. The structural decisions — whether a forward or reverse exchange, timing, identification strategy — are much easier to handle before the clock starts ticking than after.
