1031 exchange questions

[Ryan Hammond]

Hi BP community, I am planning on selling my duplex in Nashville Tn at the end of this year and have a few questions regarding 1031 exchanges. Most of my googling has pointed me to Bigger Pockets, so I figured I'd just explain my scenario with some real world numbers.

I bought the place for 180k in 2013. It is a single family home that I converted into a duplex. After a cash out refi, I owe 165k on it and anticipate it selling for around 350k. I have a few questions regarding how much I must re invest, and how I am allowed to re invest.

Am I required to re invest all 350k back into RE, or just the net profit?

Would I be able to, for example:

Get a loan on a new place for $350k, and pocket whats left over after the down payment?

Finance 2-3 investment properties/ land/ ect equal to the sale price?

I am at a bit of a crossroads and want to play this hand correctly, and I'm not sure what my restrictions are. Any and all info / advice would be greatly appreciated.
