Introduction

When it comes to determining the fair price of a house, several factors come into play. One of the most important factors is the neighborhood comps, which provide valuable insights into the local real estate market. In this article, we will explore how to use neighborhood comps and the line of best fit to determine a fair price for a house.

Understanding Neighborhood Comps

Neighborhood comps refer to the sales data of similar houses in the same neighborhood. This data is used to determine the fair market value of a house. By analyzing the sales data, real estate agents and appraisers can identify trends and patterns that help them determine the price of a house.

The Line of Best Fit

The line of best fit is a mathematical concept that represents the best-fitting line to a set of data points. In the context of neighborhood comps, the line of best fit is used to model the relationship between the size of a house and its price. The line of best fit is typically represented by a linear equation of the form y = mx + b, where m is the slope and b is the y-intercept.

The Given Line of Best Fit

In this case, the line of best fit is given as y = 0.074x + 50.48. This equation represents the relationship between the size of a house (in square feet) and its price (in dollars).

Determining the Fair Price

To determine the fair price of the house, we need to plug in the size of the house (2100 ft^2) into the line of best fit equation. This will give us the predicted price of the house.

Calculating the Predicted Price

To calculate the predicted price, we need to substitute the size of the house (2100 ft^2) into the line of best fit equation.

y = 0.074x + 50.48 y = 0.074(2100) + 50.48 y = 155.2 + 50.48 y = 205.68

Rounding the Predicted Price

Since the predicted price is $205.68, we can round it to the nearest cent. This gives us a predicted price of $205.68.

Comparing the Predicted Price to the Options

Now that we have the predicted price, we can compare it to the options provided.

A. $205.88 B. $176,000 C. $206.00 D. $176,000

Based on our calculation, the predicted price is $205.68, which is closest to option A.

Conclusion

In conclusion, we have used the line of best fit to determine the fair price of a house. By plugging in the size of the house into the line of best fit equation, we were able to calculate the predicted price. Our calculation showed that the predicted price is $205.68, which is closest to option A.
