Knowing your market ?

[Frank Dortilus]

Can someone please give  me  a detail information on exactly what knowing Your market is?

I know the area I want to invest in, and I'm assuming that knowing your market is have the understanding on how much the property you interested in is going for ? The crime rate, school score, employment rate, and what the future holds for that area. Where can I get that information from? I apologize if I should know this already ,
