Thinking of Buying in Thomson

I was talking to a friend who is considering buying their first home here in Thomson and they mentioned that the median home value of $117,000 is quite a bit lower than the state average, which is really attractive to them. With homes being 56% below the Illinois median, I think it's a great time to invest in our community. What do you think is the most important thing to consider when looking for a home in our area?
