Can I use a 1031 on the sale of my primary residence?

[Jillyan MacMorris]

I own and live in a condo, but my building is being sold in a deconversion! An offer has been accepted and I we are in the 60-day closing period as we speak. Can I use a 1031 exchange on my primary residence to purchase a new primary residence? Or only on investment properties?

I purchased my existing condo as my home, but started renting it out on AirBnb a few months ago. Would it then count as a rental property for this purpose? I intend to house hack the next property, opting for an owner-occupied conventional loan. Does a 1031 only apply for loans on properties which are 100% rentals from the start?
