Expense Rule of Thumb for Single Family Houses?

[Nathan Emmert]

I understand the tried and true 50% rule (or guideline) for rentals but that is based on apartments, i.e. multifamily dwellings.

What's the rule for single family houses?

I would assume it would be lower as expenses often paid for by a landlord on MFH such as landscape upkeep, sidewalks, water/sewer/garbage, etc are transferred directly to the renter in a single family dwelling??
