The operating company takes on all of the liability that would otherwise blow back on you including: paying property management, paying contractors, collecting rent, marketing, etc.

This might involve debt restructuring, seeking alternative financing, or even offloading non-performing assets.

Although I wouldn't recommend a 10 year career professional to dive head first into Real Estate and quit their job on a whim, you're in a position where you have your entire life in front of you and likely have yet to incur debts that need to be paid and other real world expenses.  

Other considerations things to look at include; are any utilities common (like paying for a boiler for all 4 units instead of individual furnaces), how does access/common areas work, do the tenants all have access to laundry, are there any common area utilities (light common area lights, electric or gas for laundry) that would stay in the owner name.  

that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases.

This has included taking a property that was getting very run down and remodeling.  

Depends on your credit score and debt to income ratio etc .If it us full doc and it is a primary residence sounds a little high . if it is an investment sounds pretty solid .

When I started I scaled back my lifestyle, sold stuff, and got debt free to fund my first rehab. 

there are more than a few of us who have had this happen to us here on BP.. myself included.

If you are in fact referring to gross rents, then yes you can get gross rents well above that but after all expenses, includeing debt service, PM, maint, cap ex reserves etc, a good deal is about $100 - $200 a door in pure cashflow.
