Do I need to spend cycles focusing on formally structuring my business at this point?

There are countless ways to structure the deal but make sure you have a formal contract written up with an attorney bc I AM NOT A LAWYER NOR GIVE LEGAL ADVICE.

I know taxes can be very complicated, but could someone please give me the heads up on why it's financially better to invest over the border in North Carolina, than here in South Carolina?

I told her already that the lease is binding and that only made things worse and she is now "formally intent on not renting the house".  

There's not a lot of Alberta specific MF meetups because:Market size is smallMost investors think of condos/houses as opposed to multifamily (hence, less interested investors)Debt-financing is hard to come (relative to the US)Institutions are not as investor/landlord friendly (relative to the US)Lots of Canadians invest south of the border for all of the above reasons plus better returns/liquidity/currency diversification. 

I have no formal experience in the industry, but became interested in real estate investing after participating in the ACE mentorship program.

I currently live in Mass near the Southern NH border so primarily interested in the Greater Lowell/Nashua area, moving to NH next month. 

I will be focusing on Fulton County, GA; and other metro counties that borders Atlanta, GA. 

Do I have to do anything to formally update the assignments for my notes?

Keep it all formal and be patient.
