Opinions needed! Typical Metrics for a SFH cash-flowing rental

[Jimmy O'Connor]

Hello again Bigger Pockets Ethos!

I am currently in need for some data from investors in the Philly and Delaware County Marketplace for rentals. I currently have newer investors, who I feel, are over allocating expenses for single family rentals (typically 3 bed, 1 bath, no central AC units) to the point where it is becoming impossible to find them a deal that cash flow when they run their numbers.

I'm curious to gather the opinions and formulas to start introducing alternative calculations from seasoned investors for typical expenses like insurance, mortgage, maintenance, capex (if that is not already included in maintenance), property management, etc.
