Primary Residence Sale ➡️ House Hack

[Kevin Queen]

Hello all, I'm in the process of building a new home with the intention to have a MIL-type suite built over the garage as a rental space as part of a house hack. Our primary residence is purely just our residence with no investment or rental portion. Since a section of the new home will be investment property, can I use any/all of the funds from our primary residence sale as a 1031 exchange to go towards the new build? Thanks in advance.
