Unfortunately house hacking is kinda out of my reach.I have a 3 bed 2 bath primary that my wife and I live in with my 2 adult sons,which need to start investing in there own home by now lol,20 year old and a 23 year old.And my wife loves animals so some of those too.So I come with a lot of baggage to house hack I believe,unless there is a way I am not aware of.Sounds like your off to a great start,keep going forward!

This provision allows $250,000 tax exclusion for a single person or $500,000 tax exclusion for a couple. 

There is no $250K exclusion for a 1031 exchange.

My question is can I legally modify the lease to add the 2 additional adults and increase rent by $600/mo? 

This exclusion does not apply to investment property. 8)
