@CK Hwang how manipulatively beautiful.....and that is said as a compliment.  

No idea.As far as manipulating the data for your own properties, how could anyone be so critical?

It depends too much on how much you put down, what term mortgage you have, interest rates etc, all financing terms you can manipulate to get any cash flow you want.

Heating oil will also jell at very cold temps. 

Before getting my current job, I interviewed with a Coldwell Banker brokerage in South Tempe and really enjoyed my meeting there.

Washer/Dryer in upstairs unit only. 5 star rated home, walls 18" thick.Summer months:Electric between $250-$350/monthFuel between $100-$150/month (60-100 gallons) when turned on, some months we just turn the boiler off (JUN-AUG)Water/Sewer free except septic maintenance. so far this has been $0 total, but I expect to maybe get it pumped just in case late this year (rough guess $300)Winter months:Electric between $350-$450 monthFuel varies greatly with temp, heaviest usage months, I've purchased 300 gallons per month at the extremes of -40 and below temps.Water/Sewer still no monthly actual cost, but I plan on about $25/month to save for annual maint.When I average out my fuel costs simply taking fuel expeditures divided by 12 months, I get approx. $200/month.

You also need to be sure the tenants do not have access to the temp control.

Sometimes it has to do with the temps .

These are highly configurable and have the ability to set a temp range and lock it out so that it can't go above or below a max.I have a digital watchdog commercial grade camera system.

Apparently they said the thermostat at 77 but the room temp still reads as 80 degrees.
