Are you up to date on all of your licensing and permitting to legally rent this duplex?  

They can also handle all the paperwork and help with any legal stuff you might need to know.One thing that can help you and your tenants in the future is making sure your renters get renter’s insurance.

I have been managing this one property where everything has been going well and housemates have been happy and even renewing their lease for the past couple of years with no complaints.

My advice for establishing a trusting wholesale relationship is to get properties under contract and controlled legally, after which you can start having a conversation about agreements.

The good thing about househacking a legal multifamily unit is that lender allows you to use the vacated units of 75% market rent as an income to offset the potential current mortgage.

The property owners IN MASS burnt down their properties, which, since they did not file insurance claims was actually the only LEGAL way to free themselves of the continuing negative cash flow of these buildings.  

Will this optimize your tax position or legal position?

I've heard of house hacking cases where the tenants essentially evict an owner with false complaints to the rent board. 

I am fairly confident in my choice of the syndication and just need someone to go over the numbers to confirm my understanding of the exit strategy when time comesI've invested in syndications, but I'm not willing to read your contracts and give you legal advice.

This is not tax or legal advice; engage those professionals.
