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.

I would have the tenant pay for electricity, heat and gas.Monthly expenses are calculated at $1,174.01 leaving me with $25.99 in cash flow, 3.28% pro forma cap, 0.92% COCROI and 5.04%. 50% and 2% rule says this is a good.

SFR have heated up.

Does it need work to the systems like a new heating system?

It will do this without loosing energy that was used to heat and cool the house. 3.

What kid of heat is used?

It would be my primary residence for at least a year, so I'd want it to be nicer than a standard rental rehab i.e. hardwood floors throughout (maybe bamboo to cut some of the cost), exposed brick walls, 1.5 baths, subway tile in full bath, central air/heat with exposed ductwork, rooftop deck if city approves & budget allows (not a necessity though).
