Analysis and insights

Analysis and insights
  • The client has a presence in seven areas of Chennai, which is one of the top cities with a growing real estate market. We did a sales performance analysis and the observed trends in the data can be attributed to a combination of various factors, including market conditions, infrastructure development, location attractiveness, buyer preferences, economic factors, and changing demographics. By understanding these reasons client can make informed decisions, identify opportunities, and tailor their strategies to meet the evolving demands of the real estate market.
  • During 2011-2012, property sales were limited to the Velachery area. This suggests that the client market was primarily focused on this locality during that period. The reason for this is attributed to factors such as the availability of attractive properties, infrastructure development, proximity to amenities, or specific market conditions that made Velachery a preferred choice for buyers.
  • From 2013 to 2019, there was an expansion in property sales across all areas. This indicates a broader market growth and increased demand for real estate properties in various locations. The reason for this expansion is attributed to economic growth, improved consumer confidence, favourable lending conditions, urban development initiatives, or increasing population and migration patterns.
  • In the years 2020-2022, property sales were concentrated in specific areas, namely Anna Nagar, Chromepet, and T Nagar. This suggests a shift in buyer preferences or market dynamics during this period. Potential reasons for this concentration are the emergence of these areas as attractive residential or commercial hubs due to factors like infrastructure development, accessibility, amenities, or evolving market trends and preferences.
  • Chromepet stood out as the area with the highest number of property sales throughout the ten-year period. This indicates that Chromepet has been a popular and sought-after location for real estate investments. The reasons for Chromepet’s popularity include its strategic location, affordability, infrastructure development, connectivity, availability of amenities, and growing employment opportunities in the area.
  • There was an overall increase in sales from 2014 to 2018, highlighting a period of market growth and high demand for properties. This growth is attributed to factors such as a strong economy, favourable market conditions, low-interest rates, increasing urbanization, and a growing population.
  • The data reveals that house with 3 to 4 rooms were the most popular among buyers. Additionally, during 2015-2019, houses with 6 rooms were only available in KK Nagar. This information provides insights into the buyer preferences for specific room configurations and the limited availability of larger properties in certain areas. The popularity of houses with 3 to 4 rooms is due to the preferences of families or individuals seeking comfortable living spaces, while the limited availability of houses with 6 rooms in KK Nagar is influenced by factors like land availability, zoning regulations, and the local market demand.
  • Commercial buildings recorded the highest number of sales over the fifteen-year period compared to houses and other property types. This suggests a robust demand for commercial spaces and indicates potential opportunities for developers and investors in the commercial real estate sector. The demand for commercial spaces is driven by factors such as economic growth, business expansion, increasing entrepreneurship, favourable investment returns, or the development of commercial hubs.

Area wise analysis:

Area wise analysis:

The data encompasses seven prominent areas of Chennai, namely Adyar, Anna Nagar, Chromepet, Karapakkam, Velachery, KK Nagar, and T Nagar. These areas are recognized as significant hubs within the city’s real estate market, each having its own unique characteristics and appeal. By analysing the sales performance in these areas, we can gain valuable insights into the dynamics of the Chennai real estate market and identify trends and patterns specific to each location.

  • T Nagar has the highest registration fees, indicating that property transactions in this area involve higher costs and government charges. On the other hand, Chromepet has the lowest registration fees, suggesting that property transactions in this area may be relatively more affordable for buyers. The variances in registration fees are attributed to factors such as property values, local regulations, and government policies.
  • KK Nagar has the highest commission rates, indicating that real estate agents or brokers operating in this area charge higher fees for their services. Conversely, Adyar has the lowest commission rates, suggesting that real estate transactions in this area involve lower agent commissions. The differences in commission rates are influenced by factors such as market competition, agent expertise, and negotiation practices.
  • The areas of Anna Nagar and T Nagar have the highest average sales prices, indicating that properties in these locations command higher market values. This is attributed to factors such as desirable neighbourhoods, proximity to amenities, and perceived value associated with these areas. On the other hand, Karapakkam has the lowest average sales price, suggesting that properties in this area is more affordable for buyers.
  • Chromepet and Adyar have the smallest average sqft area for properties, indicating that homes in these areas are generally more compact or have smaller living spaces. In contrast, KK Nagar has the largest average sqft area, suggesting that properties in this area offer more spacious living arrangements. The variations in sqft area are influenced by factors such as land availability, construction practices, and market demand for different property sizes.
  • Velachery and Karapakkam have longer “Days on Market,” indicating that properties in these areas take more time to sell after construction or listing. This is due to factors such as market demand, property pricing, competition, or specific characteristics of the local real estate market. On the other hand, KK Nagar has the shortest “Days on Market,” suggesting that properties in this area tend to sell relatively quickly, possibly due to high demand and favourable market conditions.

Inference from the case study

Based on the analysis of the provided data, we can make the following recommendations for the client:

  1. Diversify Market Presence: While the client has a presence in seven areas, it would be beneficial to consider expanding into other emerging areas of Chennai’s real estate market. By diversifying their market presence, the client can tap into new growth opportunities and capitalize on the potential of different locations.
  2. Focus on High-Demand Property Types: The data indicates that houses with 3 to 4 rooms are the most popular among buyers. Therefore, the client should consider prioritizing the development or acquisition of properties with these room configurations to cater to the demand of the majority of buyers. Additionally, given the limited availability of houses with 6 rooms in certain areas, exploring opportunities to provide larger properties in those locations could attract buyers seeking more spacious living arrangements.
  3. Evaluate Pricing Strategies: It is essential for the client to carefully analyse the average sales prices in each area and align their pricing strategies accordingly. Areas like Anna Nagar and T Nagar command higher prices, so the client should consider adjusting their pricing to reflect the market values accurately. Similarly, in the more affordable areas like Karapakkam, the client could explore pricing strategies that attract price-sensitive buyers.
  4. Consider Commercial Real Estate Investments: Commercial buildings have consistently recorded the highest number of sales over the fifteen-year period. This indicates a strong demand for commercial spaces in Chennai.
  5. Consider Targeting Different Buyer Segments: The data highlights variations in buyer preferences across different areas. By understanding the demographics and preferences of potential buyers in each area, the client can tailor their marketing and sales efforts to target specific buyer segments effectively.
  6. Monitor Construction and Sales Cycles: The sales performance analysis indicates fluctuations in sales volumes over specific years in different areas. Understanding the timing of market peaks and lows can help the client optimize their inventory, marketing efforts, and pricing strategies to maximize sales and profitability.
