Electric, no one wants gas, it's an extra bill and as a landlord a headache. 

Only good thing about gas is if you are doing a rehab the gas company has/had a program where if you replaced each appliance like stove, dryer and furnace with gas ones they give you big rebates, which made them all basically free.

Experienced cooks everywhere in the world prefer gas ranges. High-end electric ranges have glass tops, and you should never put in a range with a glass top in a tenant's home, no matter how upscale the place is -- sooner or later they always crack it.

@Jim K. Next month we are remodeling a high end apartment, removing a gas range and replacing it with an electric induction cooktop and convection oven. We know we are risking a cracked cooktop but...

We have an induction cooktop in our home and we LOVE it. After owning gas for all our adult lives, our architect convinced us that induction cooktops were as responsive as gas and much, much cleaner. And she is right. 

We rent the apartment on the extended stay market which means we must do a deep cleaning frequently between tenants. Gas really is dirtier. It is close to impossible to clean the sticky residue that coats the surfaces near the gas range. That just isn't an issue in our kitchen with the induction cooktop. 

If you are concerned about a cracked cooktop, you can always require a security deposit. 

Love our 36inch Siemens (now Bosch) Induction cooktop. But the guys installing our marble counter tops cracked the ceramic glass top & it took a month to get a ($980) replacement shipped in. But it still worked with the cracked top. Cleanup is amazing.....just throw away the paper towels you cooked on top of :))

If the furnace and water heater is gas I would stay with the gas range. If the range is the only gas appliance, I'd switch it out as an all electric house is popular with tenants due to not having an additional utility bill. There's also no chance of carbon monoxide poison or a gas leak blowing up the property. We have homes with natural gas, propane and all electric.
