Updated windows will increase comfort and decrease heat costs. 

It's nice to see things heating up in Depot Town.  

Just got the okay on the sewer scope, foundation, and the heat. so that leaves Wiring, both kitchen remodel, bathroom update.

I will be only updating lights fixtures. plumbing including the stack will probably have to be replaced.two furnaces as well as the baseboard heat will have to be replaced. ( should i install mini splits?

Too many variables to consider , age of house , insulation , windows , type of heat , oil furnace , gas furnace , heat pump , electric baseboard , radiant heat , forced air ? 

On the maintenance side you can look forward to new heat pumps every few years and annual power-washing/ painting.

HVAC systems, water heaters, washer, dryer, refrigerator and heat pumps are the main users of electricity.

I was just presented chicken scratches and half completed spreadsheets on a 50 unit building.Could be an opportunity as it's a out of town landlord and the building has had its share of problem tenants.Most of the units the tenant pays their own heat, in a few, the owner does.My question:  can one do their own "financial forensics" on such a building? 

Oh I’m not worried about turning on the heat.

Any wood stoves or secondary heating units.
