Most real estate investors know a 1031 exchange exists. Very few understand that the clock starts the moment you close, and that the first 45 days are where most exchanges quietly fall apart.
Day 0: Your sale closes. Your proceeds move to a Qualified Intermediary. The clock is running.
Day 45: Hard deadline to identify your replacement property in writing. No extensions. This is where most exchanges fail.
Day 180: Hard deadline to close on your replacement property. Cross this line and your equity is fully deferred and back to work.
Miss either deadline by a single day and the entire exchange is disqualified. The full tax bill, potentially 20 to 30% of your profit, comes due immediately.
The investors who protect the most equity are not the ones who scramble fastest. They are the ones who started planning before Day 0 arrived.
Save this post if you are planning a property sale in the next 12 months. The timeline is shorter than most people expect.
