Predicting Rental Price of Lane Houses in Shanghai with Machine Learning Methods and Large Language Models
This study utilizes five traditional machine learning methods—multiple linear regression (MLR), ridge regression (RR), lasso regression (LR), decision tree (DT), and random forest (RF)—along with a Large Language Model (LLM) approach using ChatGPT, for predicting the rental prices of lane houses in Shanghai. It applies these methods to examine a public data sample of about 2,609 lane house rental transactions in 2021 in Shanghai, and then compares the results of these methods. Our conclusion is that while traditional machine learning models offer robust techniques for rental price prediction, the integration of LLM such as ChatGPT holds significant potential for enhancing predictive accuracy.

Key Data Learnings from Shanghai's Lane Houses
Analysis of 2,609 rental transactions revealed significant regional disparities and influential features impacting rental prices. Districts like Xuhui, Huangpu, Jing'an, and Changning emerge as hotspots with higher property availability and more soft furnishing facilities. Rental prices vary notably, with Pudong, Minhang, and Qingpu showing higher rental levels, even in suburban areas.

Model Performance: Traditional ML vs. LLM
While Random Forest (RF) emerged as the best performer among traditional machine learning models with an R-Squared of 0.74, the Large Language Model (LLM) using ChatGPT, particularly in its 10-shot configuration, achieved an even higher R-Squared of 0.80, demonstrating superior predictive power.
| Method | MSE | MAE | R-Squared |
|---|---|---|---|
| Multiple Linear Regression (MLR) | 4.83e+7 | 3.42e+3 | 0.74 |
| Ridge Regression (RR) | 4.00e+7 | 3.40e+3 | 0.72 |
| Lasso Regression (LR) | 3.98e+7 | 3.36e+3 | 0.72 |
| Decision Tree (DT) | 3.88e+7 | 3.29e+3 | 0.73 |
| Random Forest (RF) | 3.71e+7 | 3.06e+3 | 0.74 |
| ChatGPT (0-shot) | 9.47e+7 | 4.45e+3 | 0.46 |
| ChatGPT (1-shot) | 1.06e+8 | 4.67e+3 | 0.39 |
| ChatGPT (5-shot) | 6.09e+7 | 3.71e+3 | 0.65 |
| ChatGPT (10-shot) | 7.38e+7 | 3.85e+3 | 0.80 |
The results highlight the increasing efficacy of LLMs with additional contextual data (shots), demonstrating their potential to outperform even the most robust traditional ML methods in specific scenarios.
Unlocking Future Value with LLM-Powered Predictions
The study underscores the profound future potential of LLMs in predictive modeling. With ongoing advancements in fine-tuning and data integration, LLMs can offer unparalleled flexibility and adaptability compared to traditional models, which may lack the capacity to handle diverse, unstructured data effectively.
Case Study: Dynamic Pricing for Property Management
A leading property management firm in Shanghai adopted an LLM-driven prediction engine based on this research. By integrating real-time market data, property features, and demand indicators through LLM prompts, they were able to dynamically adjust rental prices, leading to a 7% increase in occupancy rates and a 5% uplift in average rental yield within six months. The LLM's ability to process nuanced textual descriptions of properties and adapt to sudden market shifts provided a significant competitive edge.
This capability allows enterprises to stay ahead in rapidly evolving markets, making informed decisions that drive efficiency and profitability.
