While living in the property, after expenses, all of my properties have operated at a paper loss with standard depreciation.

The investments will vary drastically in price based on the neighborhood your looking in & will translate to the quality of tenant. 

Having the standard analysis is excellent, but having additional criteria that are more personal might also become helpful during this process. 

The goal is to identify undervalued properties, renovate them to high standards, and sell them for a substantial profit.

This is a pretty standard ACH hold period.

But the question is whether one can actually achieve the proforma cash flow on older properties with a less economically stable tenant base.Based on your picture, you appears fairly young.My advice is buy properties in quality locations think long term 10 to 15 years - slowly and safely build your portfolio - equity and cash flow will increase over time and in 10 to 15 years you may become financially free.People talk cash flow is king but one can NOT generate financial freedom cash flow with $250,000 or $500,000 invested (equity).Even at a 10% cash on cash return, one needs $1.2M invested to generate $120K a year $10K a month.You want property to be self supporting so it needs to cash flow but once that is reached the focus in my opinion should equity growth which increases net worth.

Seriously, they are a lower-quality renter that poses a higher risk.

Generally most people you speak with are going to provide you a quote with their "standard" commission built in and anything less would be them taking a reduced commission to win your business.
