Brian - I've added air conditioning to HVAC when I needed to replace the gas heater in houses.

@Dominique OsbornMaybe you know her and maybe you don't.Well now you do.She is the chassis, the wheels, the engine of our vehicle.I'm just the body (With a tonne of dents hehe)We started the company side by side in a crappy little shared office while eating table spoons of peanut butter for breakfast and drinking $1 gas station coffees just to survive.And hear we are today.A 2 time Inc 5000 company.Then, of course, there are other folks that I'm grateful for that look after our marketing, sales, acquisitions, rehabs, maintenance and so forth.

I was doing Hard money for Gas Stations and strip malls.

Jacob I should have labeled "RGE" better as that is our Gas and electric estimated at $120/month.

To get operating costs: Most places the city water authority will give you 1&2 year averages (as will the gas and electric companies to determine other landlord provided utilities); your insurance agent should be able to give you a pretty close per door quote on insurance; you should be able to call the current trash provider for a price.

Also, our gas and electric bills did not acknowledge our address; rather, the bills both showed our address as two numbers off. 

Here's a PARTIAL list:Office rentComputers, printers & softwareInternet & phone billOffice furnitureOffice supplies: paper, postage, ink, etc.Office liability insuranceAuto expenses: monthly payment, insurance, gas, maintenance, registration/plate feesBroker license fees: annual, monthly board & MLS fees, continuing education fees, E&O insuranceEquipment: lockboxes, signs, etc.Business income tax preparation and paymentsStaff payroll & payroll taxes Time Tasks: answering phones, calling past due tenants, scheduling tours, taking marketing pics, processing those pics, writing ads, researching rent amounts, posting ads, explaining to owners how rent determined & showing where ad posted, opening & processing mail, posting payments, bank deposits, scanning documents & posting to owner & tenant portals, explaining accounting to owners so they understand their monthly statements, taking pics/videos of repairs, finding reputable handymen and contractors, confirming they're properly licensed & insured and tracking annually, verifying repairs done properly, processing invoices for utility bills, repairs, taxes, city inspections, scheduling periodic property evaluations/inspections with tenants that don't want strangers in their homes, explaining to owners why taking so long, and more & more & more...

My question is should we include internet, water, gas, and power?

If not (ie two full-time working spouses) your only other option is going into land conservation deals, solar deals, or oil and gas deals - all of which have some risks.Explained in a different way...1) There are ordinary/W2/active income on one side.

I have explored a variety of online and physical side hustles, but now it's time to transition to brick-and-mortar as I build towards my dream of creating my own private equity firm.I am officially closing soon on the acquisition of an absentee gas station and laundromat business.
