I'm afraid nobody wants to buy in my area. How can I sell?

[Taylor Nunn]

I live in a neighborhood just north of Chicago. Near multiple train stations, and easy access to lake Michigan. It's not the best neighborhood, but also not the worst. Schools definitely not the best. It all sounds good, and manageable to buy a property, renovate, and sell it. 

But how do you know people are going to want to buy in your area? Just from my small amount of knowledge, I believe there's a lot of opportunity here, but I'm afraid if i invest in a property here that I will have trouble selling it. What factors go into determining a good market to sell in?
