1031 exchange + adding TIC on new property + investment usage

[Grant Smith]

Hello, (California, Shasta County)

Navigating an interesting trade-up 1031 opportunity and thought I would turn to the community for insight.

Selling 400K wholly-owned rental property head for 10+ years. Planning to 1031 into 600K 'investment' (held for investment or rental) property with the intent to hold for 2 or more years.

1. I'm lead to believe I can add a non-spouse owner (TIC) as part of the remaining 200K to be financed (both on mortgage) - fractional ownership. Is this true?

2. If so, can the 2nd TIC owner use the property as a primary residence if I am holding for investment my TIC ownership?

3. If 2 is no, what arrangement might work.

Any insight and resources you might offer would be helpful.
