From Zillow.com, I found out that the house I live in was worth 332,000 in October, 2009, which was when I moved in. To find out the best regression model, i use the data I collected on Zillow and plugged it into my calculator. I went through all the different regression models, like cubic, linear, quadratic, etc. I found out that quartic regression is the most accurate.

The equation is 1.38x^4-24.588x^3+121.630x^2-107.510x+270.720.

In the future, the house will never drop to 100,000 because the minimum value is $114,500.

The prediction can change if the economy drops even further, which means houses may go down in price.
