Nationwide averages are about as useful to me as the average national temperature.

Joshua:I live in Wallingford, Ct.I work Part-time for a Limousine Service.Some of the slowest months in a Limo business, are January and February.The reason is, people do NOT want to deal with the weather.Canceled flights, missed connections, delays, etc.As a daily visitor to this site, I know that a lot of people live in areas, where the weather could cause problems with travel to the Denver area.I just looked at the month of February in the Denver Area, and the temperatures are from 17-49.Raymond

Dishwashers can sterilize items because the water temp and drying heat is so much higher than the water temperature used to hand-wash. 

No clue but i would like to live somewhere with an avg yearly summer temperature of 80 degrees, a beach, mountains and good food

Then you will need a price for spreading salt, or sand when temperatures are subzero or the melted snow refreezes at night.

Include a Tip sheet for how to use ovens, washers/dryers, changing temperatures in room or refrigerator, etc.simple things that tenants may decide to call you on.

Now - after a prolonged time (based on the factors of time, temperature and the amount of water) Stachybotrys will begin to develop.  

However, the temperature is a good 5 or more degrees cooler with less direct sunlight than upstairs. 

If there is no existing ductwork, I might lean towards a ductless heat pump since they are pretty efficient at low temperatures.  

I would suggest to make them put the utilities under their own name (if possible), because even if you put it as included in the rent, unless you charge a good amount, they will abuse it (turn the heater that extra temperature, take those extra 5 minutes in the shower, etc.).
