Data Science and data analytics can be used in many ways in the Real estate market. The main purpose of using data science in real estate is to collect datasets from multiple sources and extract useful information from them, Humans are not able to analyze such Big data, unlike algorithms.
Technologies used: Python, NumPy, sk-learn, Flask, matplotlib, etc.
Benefits of Data Science in Real Estate

American online real estate database company Zillow has used data science in the real estate market. Zillow determines an estimate, also known as a “Zestimate” for a house, based on a range of publicly available information, including sales of comparable houses in a neighborhood.
For this project I used the “Bengaluru House price data” dataset from Kaggle:
Let's start with the data, this dataset contains some basic information about houses like area_type, availability, balcony, location, size, price, society, bath, total_sqft i.e., a total of 9 columns & 13320 rows.
First of all, to start, we will import some libraries:
Below is the image before outline removal. We can see that some 2 BHK houses, having the same square feet and the same area, are still more costly than 3 BHK ones.
To fix this we remove inappropriate data:
After outlier removal:
We can see in the general case there are not 12,13,16 bathrooms in a normal house
And there you have it. Thanks for reading!
