We are doing individual room rentals it’s a 6,000 sq ft nine bedroom home Things I have heard to include besides basic items are air fryer insta pot tea kettle vacuum sound machine black out curtains and full length mirror We do plan to add a sauna, exercise equipment and possibly a hot tub.

Also, you don't have to be physically present/so close to self-manage. 

I think 3 per side but you could do 4 if the cost isn't much different and switch that room to an exercise or visitor room if that doesn't work.  

Specifically, is there a statistical difference in the likelihood of actually acquiring the physical property versus simply earning interest on the debt as a financial investment?

What you consume, mentally and physically, you will become.Your quality of life can be a direct reflection of your thoughts.

Because that may sway who and how you interact also.Plus what kind of money are you bringing to the table to do this, are you broke and hoping (it's purely an academic exercise) or do you have some De-naro to put into a project(???)

Court hearings revealed that instead of acquiring advertised properties, Scoutpads/MBD only purchased options on those properties and never exercised them!

As my unit counts increased, I stopped the exercise but I know maintenance/cap ex is costly..  

That means someone can physically go to the property to oversee compliance to city ordinances.

Of course, you can't protect yourself completely, but this will also help you prepare for buying the next properties a little better, and it's an exercise I generally do when I'm on a showing for a property I'm serious about so that I'm factoring this into my analysis to some degree in a "capex" reserve.Capital ExpenseRoofWater Heater x2All AppliancesDriveway/Parking LotBoiler x2FlooringPlumbingWindowsPaintCabinets/CountersStructure (foundation, framing)Components (garage door, etc.)
