1031 exchange to do an addition on primary residence

[Sebastian E.]

Here is my situation. I own an investment property that I am selling and wish to do a 1031 exchange. Is it possible to use the gains from the sale toward an addition on my primary residence. For example to build a unit above a garage. I am finding some mixed answers on the question, so some clarity from someone with some 1031 experience would be most appreciated.

Thanks for the shout out @Account Closed, you've got two problems.  First the 1031 is for the sale and purchase of investment property only.  You cant use it to purchase your primary residence.

Secondly, you can't exchange into improvements on property you already own.  The IRS does not consider construction on land you already own to be the purchase of real estate.
