As China's pillar industry, the property market has suffered a considerable impact in recent years, with a decline in turnover and many developers at risk of bankruptcy. As one of the most concerned factors for stakeholders, housing prices need to be predicted more objectively and accurately to minimize decision-making errors by developers and consumers. Many prediction models in recent years have been unfriendly to consumers due to technical difficulties, high data demand, and varying factors affecting house prices in different regions. A uniform model across the country cannot capture local differences accurately, so this study compares and analyses the fitting effects of multiple machine learning models using February 2024 new building data in Changsha as an example, aiming to provide consumers with a simple and practical reference for prediction methods. The modeling exploration applies several regression techniques based on machine learning algorithms, such as Stepwise regression, Robust regression, Lasso regression, Ridge regression, Ordinary Least Squares (OLS) regression, Extreme Gradient Boosted regression (XGBoost), and Random Forest (RF) regression. These algorithms are used to construct forecasting models, and the best-performing model is selected by conducting a comparative analysis of the forecasting errors obtained between these models. The research found that machine learning is a practical approach to property price prediction, with least squares regression and Lasso regression providing relatively more convincing results.

Abstract
With the rapid development of urbanization, the development and construction of new towns and new areas has become the main direction of urban expansion. On the contrary, the development of the old urban areas has been neglected and gradually fell into recession. In the new era, how to promote the new vitality of the old city and realize the double wheel drive between the old city and the new city has become an urgent research topic. Enning Road, located in the old urban area of Liwan, guangzhou, gathers the essence of Xiguan arcade building, but once became a typical example of the decline of old blocks. Through micro transformation, it not only protects the authenticity of the historical environment, but also promotes the development of the cultural tourism industry, realizes the regeneration of the historical and cultural blocks, and walks out a unique road to the revitalization of the historical and cultural blocks. Based on this analysis, the article puts forward policy suggestions to further improve the revitalization of historical and cultural blocks from the aspects of establishing a diversified participation mechanism, correctly handling the relationship between the protection and development of historical and cultural relics, and preventing violations of consumer rights and public interests.
