I'd buy the quintessential Charleston townhome, in the city near the water, complete with courtyard and gas lights and do the Airbnb thing.

Which we did at a local gas station.

Are the tenants paying their electric/gas?

I'm looking for someone to bounce some numbers/concerns off for a potential gas station purchase. 

Coal and coal bed methane gas and mining rights and all rights incident to the extraction or development of coal or coal bedmethane gas heretofore conveyed, excepted and reserved by instruments of record; the right of surface, lateral or subjacent support;or any surface subsidence.12.

Its not like you are investing in commercial properties that has a Walmart or a gas station or something on it at which point I'd personally recommend the LLC.Just one other thing to note. 

I have a triplex that has one natural gas furnace that heats the entire building.

I work in the Oil and Gas sector with a wage of 220k CAD per year.

If I'm reading the Illinois Rental Property Utility Service Act correctly, it looks like 7 days is required: "This Section does not prohibit temporary utility shutoffs in cases of emergencies such as gas leaks or fire or, upon 7 days written notice to each affected tenant, temporary shutoffs required for building repairs or rehabilitation." 

Have enough room in your panel for an electric tankless (they take 4 spots) if no gas?
