On this case examine, I discover tips on how to predict Airbnb costs in Sydney utilizing varied options equivalent to location, property attributes, and host traits. By constructing a machine studying mannequin, I goal to uncover the important thing drivers behind itemizing costs and assist hosts optimize their pricing technique.

The objective of the venture is to develop a machine studying mannequin that may predict the worth of Airbnb listings in Sydney, Australia, based mostly on options like location, variety of bedrooms, and out there facilities.
I carried out an exploratory knowledge evaluation (EDA) to know the distribution of the important thing options within the dataset and the way they correlate with costs.
Histograms of Key Attributes
- Minimal Nights: Nearly all of listings have a minimal night time requirement of lower than 100 nights, which means that Airbnb listings in Sydney are usually used for short-term stays.
- Safety Deposit: The safety deposit reveals a extremely skewed distribution, with most listings requiring no deposit or a really low deposit, whereas just a few listings require giant deposits.
- Cleansing Payment: Most listings have cleansing charges beneath $200, with a protracted tail of listings charging extra. This may increasingly point out that high-end or bigger properties are charging additional for cleansing companies.
- Accommodates: The variety of visitors {that a} itemizing can accommodate is concentrated between 2–4 visitors, which probably displays the widespread measurement of flats and small properties in Sydney.
- Bedrooms: The variety of bedrooms is closely skewed, with most listings having 1–2 bedrooms.
- Bogs: Just like bedrooms, most listings have 1–2 bogs.
Scatter Plot of Listings by Location
The scatter plot reveals that listings are denser in central Sydney, and costs are probably larger in these clusters as a consequence of proximity to key places just like the Opera Home and different vacationer sights.
Improved Visualization
The improved visualization color-codes the factors based mostly on the variety of evaluations for every itemizing. Listings with extra evaluations are typically in higher-density areas nearer to the town middle, they usually usually have larger costs. This means that location and status (indicated by the variety of evaluations) are necessary components in figuring out Airbnb pricing.
Understanding the connection between totally different attributes is essential for constructing a predictive mannequin.
Housing Costs Scatterplot
As anticipated, the scatter plot reveals that listings with extra bedrooms are likely to have larger costs. Nevertheless, there are some outliers, indicating that components aside from the variety of bedrooms (equivalent to luxurious facilities or location) would possibly play a major position in pricing.
Correlation Matrix
The scatter matrix plot reveals the pairwise relationships between variables like value, accommodates, bedrooms, and evaluate scores.
- Value and Accommodates: Listings that may accommodate extra visitors are likely to have larger costs, although there may be variability.
- Value and Evaluate Rating: Larger evaluate scores are correlated with larger costs, suggesting that high quality and status could enable hosts to cost extra.
- Bedrooms and Accommodates: Listings with extra bedrooms are capable of accommodate extra visitors, however the correlation isn’t completely linear, as different components like the scale of rooms or the supply of additional beds can affect this.
After the exploratory evaluation, I constructed a number of machine studying fashions to foretell Airbnb itemizing costs. I experimented with:
- Linear Regression
- Choice Timber
- Random Forest
- Gradient Boosting
- Location: Properties nearer to central Sydney and vacationer hotspots command larger costs.
- Measurement: Bigger properties (with extra bedrooms and bogs) cost considerably extra, probably as a consequence of their potential to accommodate extra visitors.
- Facilities: Extra options like cleansing companies and safety deposits are related to larger rental costs, as they cater to a extra luxury-oriented clientele.
- Host Repute: Listings with extra evaluations are likely to have larger costs, probably as a consequence of belief components and higher service high quality.
This venture demonstrates how machine studying may be utilized to foretell Airbnb costs successfully. By analyzing varied options, I used to be capable of establish the important thing drivers of itemizing costs. Hosts seeking to optimize their pricing technique ought to give attention to location, property measurement, and providing premium facilities. Future enhancements might embody analyzing seasonal tendencies and incorporating exterior components like demand throughout occasions.
