If they have a thermostat in their unit, that means they are a separate zone on the gas heat.

I want to separate the size into maybe four groups.

If you see a 6 unit that has 2 separate units both listed for rent and it's not remodeled, probably a higher chance of landlord fatigue.  

Not sure if I should structure as a traditional home sale + a separate business package including all accessory structures, furniture, biz ops, STR license, etc.Maybe as an add on if someone wants to use it as a hostel business as well but still open to a traditional buyer purchase separately. 

Either work but in Metro Atlanta, the easier option is an SFR with roommates or potentially separating the basement as a separate lease space. 

Open a separate checking account dedicated to marketing and budget 6 months of mail, so if you have $6k, you would do $1k per month with 1/4 of that dropping every week.

House hacks are not like a traditional investment property and admittedly a little more emotion will play into whether it's going to work or not for you.

As a general rule, each entity that files a separate tax return (partnership, s-corp, c-corp, etc) will need its own QBO subscription.

Since most real estate purchase agreements do not assign value to each category, taxpayers must understand what options are available to determine the appropriate allocation to land and building.Taxpayers are required to separately identify the value of non-depreciable items (i.e., land) from the depreciable building and site improvements.

@Max Bellino if you feel the need to interview six separate attorneys for this scope you are over complicating your true needs.
