  • 45-Day Rule: Must identify replacement property within 45 days of closing.
  • 180-Day Rule: Must close on replacement property within 180 days.
  • Equal or Greater Value: To defer 100% of tax, the replacement property must cost the same or more than the relinquished property, and you must reinvest all equity.
