It varies a lot property to property but roughly: Taxes 10%, Insurance 5%, Vacancy 7%, Repairs 8%, Capex 5%, Property Management 10%, Services like Landscaping, Snow removal, pest control 5%.

I provide in "special provisions of my lease" that anything under $100 is tenant responsibility.I also clarify a list of common repair examples that I expect tenant to repair, and a list of common repairs I would rather make myself.Tenant: smoke detector batteries, filters, small plumbing leaks under sinks, clogged drain, loose handles, loose screws, pests (toilet handle is a little odd but I would likely take care of it.)Landlord: Major leaks, sewer smells, roof leaks, water heater, hvac, cracked tile, broken faucets, broken toilets."

Large  multifamily 30+ tends to have lower ROI than the 12-20 units from what I've seen.Things To Consider (Multi Family)Income: Gross Income, Laundry, Storage, Garage, Signs, Solar Panels, Cell Phone Antenna, Expenses: Common area utilities, Heat, Sewer, Water, Insurance, Landscaping/Snow Removal, Pest Control, Professional Fees (Accountant, Eviction Attorney), Repairs, Maintanance, CapEx (Reserves for Boiler, Roof, Etc.)
