King's County Data Set


The Problem:

Predict the sale prices of houses as accurately as possible.

Why? Because we to be able to sell houses that people will want to buy and make money.


The dataset -- King's County Data Set

What I needed to do:

  • Clean the dataset of all the null values and make sure that there were no datatypes did not match up correctly
  • Continue going through the data and clearing outliers and checking for multicollinearity.
  • Focused on features that will sell like:
    • Price/Sqft
    • 3 bedrooms/ 2 baths
    • Quality of homes
  • Variables used for the model were:
    • Continuous variables
      • price_per_sqft
      • sqft_living
      • sqft_lot15
    • Categorical variables
      • quality
      • bathrooms
      • bedrooms
      • view
      • condition
      • floors
      • waterfront
  • After determining the values that were categorical and continuous I ran an OLS stats model to check for how well the variables will fit to the model.
    • 0.974

Recommendations:

  • Houses with 3 bedrooms and 2 bathrooms are being sold at a high quality mark of 8.
  • The average condition of a house is 3, which is the middle of the way of best condition.
  • Houses can be sold for an average price of 450,000 at midway condition and descent quality.
  • The zipcodes that adhere to these conditions are:
    • 98125
    • 98059
    • 98028
    • 98034
    • 98144
    • 98011
    • 98136
    • 98072
    • 98065
