Evicting During Winter Months

[Ivan Cortez]

I have a duplex in Wisconsin and the upper tenant has just notified me that she lost her job 3 weeks ago and doesn't have money for rent this month. She said she has requested a check out of her 401K to cover rent but doesn't know when the check will arrive. When we mentioned possible eviction for non-payment, she was shocked that we would consider evicting her during winter. 

For context, the tenant is an elderly lady in her 70's who lives alone. I am writing this post in December in Wisconsin. She is currently just on a month-to-month. 

From what I have read, it is perfectly legal to evict someone in the winter. The fact that she is elderly and living alone does make me pause and consider what other options there may be which is what brings me here. Any thoughts on how others might handle this situation?
