Partial 1031 Exchange

[Jas Sarn]

I am looking for a 1031 exchange to sell one property in California / SF Bay Area to multiple properties in other states.

I bought the home for $200K. It is worth now $600K. I plan to invest the $400K of gains in potentially 2 homes in other states and generate more rent and also diversify out of CA (as my primary residence is also in CA)

Will my original $200K investment on the home that I am selling  (I plan to cash this for different uses) considered a Boot ? If yes, Why should it be ?

I am not making any capital gains from this transaction as I am investing ALL of the $400K in capital gains back in real estate through 1031

Thanks
