A triplex with one boiler where the owner cannot bill the tenants for heat
Take a triplex where a single boiler feeds all three units. Anyone with construction experience knows what that boiler costs to replace, so the capital side is not the scary part. The operating side is. The seller pays heat for all three units and it shows up as about $340 a month in the winter months on the utility statements. In a lot of places an owner cannot simply divide the gas bill three ways and bill it back, and would need real submeters or a formal allocation to charge for it at all. Is that a code thing or a lease thing? And if the owner is stuck paying it, does the appraiser or a future buyer discount the building for it?
