Taxes on land contract in 2017 in WI.

[Nate Martin]

I purchased a home through a land contract in August of 2017 for 90k and was paying the seller's mortgage up until January of 2018. I closed on it in January. The taxes for 2017 were escrowed into the mortgage  that I was paying, and was paid in full in 2017 by the mortgage company. What tax liabilities do I need to be aware of? I live in Wisconsin.
