You could also look at mini-splits as an option, which are generally much more efficient than electric heat/AC.I agree with Anthony though - $800 per month for 14 units is not all that high. 

My AC vendor said that with the multiple bedrooms that mini splits couldn't pick up the necessary load to cool the house, so we went with a central unit per apartment. 

My wife and I bought a new mini van all cash and I am wanting to put a LoC on it.

@Antone JAmes As Russell mentioned, for a conventional loan the min is 15% down for a 1-unit.

If we are talking about rental property, I buy the cheapest: switch & plate covers, mini blinds (even expensive ones get wrecked), toilet paper holders, etc.

Having lived overseas for a number of years I have grown accustomed to the mini-split heating and cooling used in many parts of the Middle East and Asia. 

Take a look at mini splits they are very efficient but only heat down to about -15 degrees.

These old-school mini furnaces stand alone on the kitchen or living room floor and are supposed to throw heat around the apartment.10.

One of the neighbors down the street knocked on the door and told him how that car was bring down the look of the neighborhood . ( bmw's and mini vans ) .

My biggest want is to be able to step away from work multiple times a year and take multiple "mini retirements" with my family.
