Only 1 for Furnace for Multi-unit

[Sarah 'Sadika' J.]

Hello,

I’m considering purchasing a multi-unit in Baltimore. It comes with 3 water heaters, 3 separate electric panels, however landlord pays for heat since there is only 1 furnace. I want to have tenants pay for heat and it’s gets very expensive. How do you go about splitting heat? Should I switch in baseboards? Any advice? Thank you
