Unless this is a wall oven, most ranges are a standard size.

I think you are mostly correct but here are some examples I have of going the opposite direction:I was removing a load bearing wall.  

How are the foundation walls, basement/crawlspace framing, HVAC/heating & cooling, roof, windows, elec.?

Why would you give them free rent with they still have full access and use to the stove, refrigerator, walls, closets, flooring, roof, garage, lawn, etc.?

My plan is to use the LLC to acquire properties and to be the employer for the property manager when I actually acquire some walls and a roof besides my own personal home.

Be attentive to damp ceilings or walls, which could indicate plumbing failures.Structural issues are critical to monitor.

I found this odd, so I decided to call Cobb County and they advised that a basement can only be rented by one adult with some kind of square footage per person limitation, and I could not wall off the basement door.

so just make sure you're not excluding properties because you're looking for 'cash flow.' that's not the point of a house hack, the point is to build equity.off market deals - you can go direct to owner or connect with wholesalers and others that surface off market deals.
