Tough to beat this answer from @Michael PlaksYou can also check out these two recent posts that walk through Section 121 Exclusion and 1031 Exchange guidelines and strategyHow Section 121 Exclusion and 1031 Exchange works: https://www.biggerpockets.com/forums/51/topics/1195208-1031-and-sec-121-experts-want-to-sell-rental-but-tax-worried What not to do if you don't meet the requirements for Section 121 Exclusion and 1031 Exchange:  https://www.biggerpockets.com/forums/51/topics/1195383-5k-for-cap-gains-tax-opinion-quote-that-reasonable ...

I had signed up for a 3rd investment at a very early stage for another 400K thru a 1031 exchange.

with the intention of doing a 1031 exchange on that property and the goal to utilize Brandon Turner's "stack" method to dump the proceeds into a bigger property with more units in a similar market within Worcester county.

Can some of the members of an LLC do their own exchange or cash out at the time of the sale of the property?

You can message me on the BP messages so we can exchange some contact info.

depends when you sell. talk to a 1031 expert. what matters is intent. if you bought it to sell for profit then yes you'll pay your normal tax rate. if it is for investment and you can prove that you can 1031 exchange

.: @Jonathan GreeneThat's exactly what I was thinking all through the crackpot initial person exchange in your thread.

Feels like Partial 1031 Exchange would also be an opportunity, correct me if I'm wrong @Dave Foster, if you continue to rent out the property after the sale. 

I'd be very wary of someone asking to rent it in exchange for doing work on it. 

In exchange I was hoping this could be a learning opportunity to help pave the way and set me on the right track for when the time comes after high school to purchase my first investment property and start the snowball.
