Gas boiler or Electric baseboard: Is it all just preference???

[Jonathan Santiago]

I just recently got a 3-unit building under contract that currently has no heating system in the home. I am trying to decide between rewiring the entire house and putting electric baseboard (this would also get rid of knob & tube wiring in basement) or getting 3 new gas boilers to heat the house that way. Everyone I ask has their own opinion, but definitely the most common response I get is if the whole house is electrical baseboard then the tenants are going to have extremely high electric bills in the winter (Boston area). Although that may be true, isn't it basically the same thing as gas heat because instead of 1 high electric bill, they would have a low electric bill and a high gas bill in the winter? Is this thinking flawed? Also if I choose to install new gas boilers, I still need to update much of the electrical in the house. From a rehab perspective, is there a significant cost savings for doing electric everything vs gas heat & stove with some updated electrical? 

Definitely excited for this project but this choice definitely has me a little worried about making the wrong choice. The plan with this property is BRRRR and if the rehab hits the top end of our budget it will become a flip. Any insight and/or expertise on this subject would be greatly appreciated.

Thanks
