Project Description

Landed Property has always been seen as something for the wealthy, with only the top 5% of Singaporean earners being able to afford it. For Singaporeans who aspire to own such Property, there are currently many available options – Terrace Houses, Semi-Detached Houses, Corner Terrace Houses, Detached Houses and many more. Due to fluctuating property prices, it may be difficult for an aspiring landed property owner to properly plan and budget to get their dream house. Furthermore, existing owners may be stressed about when the best time to sell is.

Our project aims to shine light on this by providing an accurate geographically weighted regression model using factors such as location, tenure and type of sale to predict future landed property prices. Now, aspiring owners can filter by location and type of house, and easily see what their dream house would be worth in several years. Alternatively, owners of landed property who plan to sell can see if they should do so sooner or later.

Landed Property purchase and sale is a huge financial commitment and we at GeoEstate are committed to ensure that you make the best financial decision for you and your family.

Tools & Technology

Challenges

No.	Key Challenges	Mitigation
1.	Unfamiliarity with R, its packages and R Shiny	Self-directed learning with online resources such as Datacamp, Browsing community forum (Stackoverflow / discuss.onemap) for help Looking at official documentation for various packages
2.	Limited oneMap API call for standard account	Creation of R script to catch timeout & wait Filtering out distinct records to query oneMap to reduce the quantity of duplicated request
