Gas if available. Not even a decision.
its a rental who wants to go in there yearly and flush it at your cost/time/money.15 years is good for any appliance.
Put a Rinnai gas tankless in there and call it a day.
We have one and love it.
and since its a rental the energy cost don't concern me.
I feel15 years ago i put in a NG tankless water heater into the home i was living in.
How long have you had your tankless?I have owned all 3 in my life. In order of preference:
1 - NG Tankless, this is what I currently have. Full disclosure, I have not had any issues with it so I am biased favourably towards it. This would change if it had expensive electronic issues. It is a complicated device, has a microprocessor in it to handle complex logic (from firing gas to recirculation timing etc.), numerous sensors, etc. but to date has been solid as a tank, even with power bumps. I like it because it is efficient and has a very small footprint (my favorite feature). Yes infinite hot water if that matters, there are just two of us in the house but yeah if I had a big family at home this could be a factor.
2 - Condensing power vent gas tank style, very efficient, reliable. Mine have only failed from cathodic issues or rotted bottom, no different than an old school gas heater. Exhaust gas temperature is fairly cool, you use PVC piping to vent. You need 110v to run the power vent motor (very small draw, maybe 1A, while running). I would also put an old school conventional gas heater here at #2 in my choices as well, I have had many of these, but I would always buy a high efficiency modern power vent given the choice if replacing or doing a new install.
3 - Electric, mine was fine, needs 220v, quiet I guess is a feature, no burner noises. Not as economical as gas anywhere I have lived, that may change as carbon taxes / penalties get further implemented. Currently gas still wins. Ours took 45m to recover after turning it on from a vacation, I honestly can't remember how long my traditional gassers were but it definitely wasn't 45m. My tankless is instantaneous of course.
I iwIsh I had a tank, our new home has a Rianni tankless.15 years is good for any appliance.

Into the 5th year now. City. I do yearly preventive maintenance on it (flush for 45 minutes, clean all filters, etc.).How long have you had your tankless?
City water or well water?
yeah direct vents are quite a bit more than a normal vent one. that is what the tankless replaced . i could throw a electric 50 gal for less than $1k into the house .Since this is for a rental, have you priced a direct vent gas water heater? I just replaced one and it was about triple the cost (w labor) compared to an electric one I replaced just a few years ago.
