Investor Perceptions of Macroeconomic Factors When Making Real Estate Investment Decisions in Colombo Municipal Council Area, Sri Lanka
No full textThis research examines the investor perceptions of macroeconomic factors when making real estate investment decisions in the Colombo Municipal Council Area, Sri Lanka. Using stratified sampling and quantitative analysis, the study found that the Gross Domestic Production growth rate and exchange rate positively influence investor perceptions, with 40% and 73% of investors considering these factors, respectively. Despite high inflation, 80% of investors consider real estate as a hedge against inflation. In contrast, Average Weighted Prime Lending Rate and Average Weighted Fixed Deposit Rate negatively affect investment demand, and it considered by 79% and 66% of investors, respectively. The Inflation Rate, Average Weighted Prime Lending Rate, and the Exchange Rate are the primary factors considered by the Real Estate Investors when making investment decisions. The COVID-19 pandemic and financial crisis impacted over 76.5% of investors significantly. Notably, 52% of investors expressed discomfort in investing in real estate under the current economic conditions
AI-Driven Investment Property Recommendations Using Spatial Big Data, Price Trends, and Amenity Mapping
No full textIn the real estate domain, investment decisions rely heavily on spatial and economic context, yet most digital platforms still provide static listings with limited personalization or geographic intelligence. The primary objective of this paper is to introduce and validate a spatially enriched recommendation system for real estate investment that integrates Artificial Intelligence (AI), Geographic Information Systems GIS), and big data analytics. Evaluated on over 70,000 property listings, the system leverages historical property trends, spatial amenity density, and price deviation metrics to identify undervalued or highgrowth-potential properties across urban areas. It combines location-sensitive scoring models with price per square foot analysis and Z-score based outlier detection to recommend listings that deviate positively from local price norms while offering strong amenity access. By evaluating properties based on proximity to hospitals, schools, banks, parks, transit, and other infrastructure, the model delivers context-aware investment insights. Key findings show the proposed model achieves a 70% match accuracy with expert evaluations, significantly outperforming baseline models. The implications of this work include a new framework for data-driven decision-making that can improve market efficiency, particularly in fragmented real estate markets like those in South Asia.
 
Consumer Behaviour and Preferences in Apartment Purchasing Decisions: Case Study in Proposed Apartment Project in Malabe, Sri Lanka
No full textThe escalating demand for housing in suburban regions of Sri Lanka necessitates a comprehensive understanding of consumer preferences in apartment purchase decisions. This study investigates factors influencing apartment purchase intentions in Malabe, a rapidly emerging suburban growth center near Colombo. Previous research has focused primarily on high-end condominiums in Colombo, leaving a gap in understanding suburban preferences and end users’ priorities. The study aims to identify key factors affecting apartment purchase decisions among potential buyers and examine preferences regarding pricing, financing, amenities and sustainability features. A Quantitative research approach was employed, using purposive sampling to collect data through a structured questionnaire survey administered to 194 respondents interested in real estate transactions. Descriptive statistics were used to summarize responses and rank factor importance. Key findings reveal that price and proximity to work are the primary factors influencing apartment purchase decisions. Three-bedroom apartments dominate demand, especially in higher price ranges. External financing is the preferred funding method, but buyers tend to maintain conservative loan-to-price ratios. Eco-features are considered important, with most respondents willing to pay a premium for sustainable features, although cost sensitivity remains high. These insights provide valuable guidance for developers and policymakers in tailoring suburban apartment projects to meet market demands while addressing sustainability concerns.
 
Phosphate Solubilizing Bacteria and Fungi Isolated from Rubber (Hevea brasiliensis) Root Rhizosphere, Their Biofilm Formation and Phosphate Solubilizing Abilities
No full textThe ability of some soil microorganisms and their biofilm combinations to convert insolubleforms of phosphorus to an accessible form is an important trait associated with plant Pnutrition. The phosphorus solubilizing potential of bacteria and fungi isolated from Hevearhizosphere and their effective biofilm communities were evaluated using solid and liquidmedia under in vitro conditions. Phosphate solubilization ability of them were tested oncalcium phosphate media by analysing the soluble P content after incubation at 28±2°C. Outof the microbial isolates, 10 bacterial colonies and one fungal colony formed haloes (clearzones) around the isolate growing on solid media containing calcium phosphate as the solephosphate source. Spectrophotometric quantification of phosphorus solubilization in theliquid media showed that the ten bacterial isolates, and ten fungal isolates solubilizedinsoluble calcium phosphate in to the liquid media in the range of 200 – 450 and 200 – 300mg P L-1 respectively. Biofilm showed significantly higher P solubilization (853.3±25.17 mgP L-1) than their bacteria and fungi counterparts alone. Phosphate solubilization of bacteria,fungi and their biofilm could be attributed to the secretion of organic acids. A significant dropin the pH of the broth media (4.7 to 5.6) compared to the pH of the control treatment (6.8-7.0)was observed. pH change in the media could be due to secretion of organic acids bymicroorganisms and/or utilisation of compounds in the broth media. Although there was asignificant synergistic effect on P solubilization due to biofilm formation, pH in the liquidmedia of their mono cultures and biofilm were not significantly different. This observationwarrants further investigation
