OBJECTIVE
The focus of this project is to understand the dynamics of pricing a house
We studied major factors that can be quantified and could affect the pricing of a house

Prices of Substitutes • Renting becomes more expensive to owning a house• Zillow rent versus buy calculator: better to buy than rent if
living in home more than 1 year and 11 months • Super low Mortgage rates

Choose houses from Zillow Parameters considered: Property ID, selling price, floor-size-SQFT,
lot-area-SQFT, price/SQFT, number of rooms, number of baths, age (month)
Track and collect data in MS Excel for 40 houses over 1 month Regression Analysis done in BI package: SAS Test the Hypothesis Test the accuracy of Regression Equation

REGRESSION ANALYSIS
Regression Equation:
• Selling_Price (House) = β1 + β2 *Floor_Size_sqft + β3* Lot_Area_sqft + β4* Pricepersqft + β5* No_of_Rooms + β6* No_of_Baths + β6* Age_months
Primary Hypothesis:
• Ho: If there is NO significant effect of independent variables on dependent variable?
β1= β2= β3=0• H1: If there is any significant effect of independent variables on dependent
variable? β1≠ β2≠ β3≠0
Secondary Hypothesis:
• Ho: The coefficient of the respective parameters is zero.
βi=0 for all i = 1 to 6• H1: The coefficient of the respective parameters is significantly different from zero.
βi≠0 for all i = 1 to 6

SAS ANALYSIS
p-value: <.0001 hence, we REJECT our Ho • Conclusion: There is significant effect of independent variables on
dependent variable.
R-Squared: 97.6% • Proportion of variance in Selling Price that can be explained by the
independent variables: Floor Size, Lot Area, Price per sqft, No. of Rooms, No. of Baths and Age in months.
Quantitative Effects of the Model • If floor size increases by 1 sq.ft., Selling Price of the house increases by
$119.5. • If price per sq.ft. increases by $1, Selling Price of the house increases
$3548.• If Age of house was 1 month older then the value of the selling price of
the house increases by $150.
