Landlording Question for experienced landlord

[Ricardo Fuller]

Hey guys how are you..

I am new to the landlording field.. I have just recently acquired a Duplex property but I have a problem with the heating source/setup and is just looking for opinions or advice. The heat as it is, is running on oil and is not split for each unit.

It has one of those Dinosaure type boiler heaters from like the 1960's that runs on oil.

But anyways my question is (I am goin to split the heating source of course) but I wanted to know which source is better going all electric with baseboards or going gas with two of the small boiler/furnace heaters...

Its a rental ofcourse, So which way is more cost effective, economical and less headache

Thank you,
All appreciated
