Because it's an attic, it's pretty cold up there in the winter, but I am planning on installing a mini-split. 

Heating costs go up in winter, as does electricity due to the reduced natural light and more people indoors.

I am from Iowa so our goal would be to use it in the winter months (dec,jan,fab) and try and break even off the income from the remaining months. 

Because we live in Wisconsin where winter sucks and there isn't a ton to do we decided to take our receipts from Aldi into our local grocery store and compare costs. 

In court, I produced text messages between myself and the tenant showing I was attempting to fix the issue, but since she said she was without heat for 3 months during the winter, it looked really bad.

There's a lot of shake out of crypto start-ups every crypto-winter.

Property taxes, income taxes, sales taxes, declining population, unfavorable rental laws, winter weather.

One small point of criticism; we were there in the winter and in the evening a lot to play a game or watch TV.

It's a good market with year-round demand that peaks in both winter (ski season) and summer (beach / lake / hiking / etc) season. 

We have had a pipe burst during the cold winter months, the roof needed to be replaced (thankfully covered by our insurance), and some issues with electrical, which hasn't been majorly updated since it was built in 1973.
