Estimates only, for a standard deferred §1031 exchange of real property, based solely on the figures you entered. This tool does not address matters such as depreciation recapture, related-party rules, reverse or improvement exchanges, installment sales or state taxes, and it does not estimate tax due. FortyFive is not a tax adviser and this is not tax or legal advice — confirm all conclusions with a qualified tax professional and your Qualified Intermediary.
