Purchasing a house is one of the most important thing in our life. However, the apartment price in Singapore is terrible and hard to be afforded. Based on 634 entries in the past 12 months from 122 contributors, the average price square meter to buy apartment in city center is S$23,611.40, some even up to S$32,291.73 per square. As for outside of center, the average price per square meter is also above S$10,000.
  
In Singapore, everyone wants to own their dream house. For the young who just start working, resale house would be a good choice as their first bulk commodity. In this project, we would present some useful information and insight regarding to resale housing market in Singapore using data visualisation, which can help our viewers grab a whole picture about the resale housing market in SG. In this case, we would focus on answering several significant considerations firstly come to mind when we want to purchase a house in SG, such as, location, price, flat type and so on. The dataset we used in this project is Resale Flat records from March 2012 to Jun 2016 took from [https://data.gov.sg/dataset/resale-flat-prices data.gov.sg].

Imagine you want to buy your new house in Singapore, what questions do you need to answer yourself before you take action. In this project, we provide some insight about 3 most important considerations we need to go through before we come to the final decision to purchase a new house in Singapore. These 3 issues we include are:
+
*What are the shares of the resale public housing supply in 2015?  
# Price. The price of a resale house definitely would be the first thing come into mind when we want to buy a new house, which can be further separate into 2 question -- "How much can I afford?" and "What is the resale housing supply condition within my budget in market?".
+
*What are the distribution of the resale public housing prices in 2015?
# Attributes of Resale House. What kind of house do we want to buy would be another aspect we need to go through. Actually, this issue can be decoded into several subset in this case -- "What about the location for the house?", "What is the type of the flat?" and "What floor range do you like?" .
+
*With reference to the findings, compare the patterns of the first-half of 2016 with the patterns of 2015.
# Time Series of Price and Supply Change. The price and supply would change time to time in housing market. Form historical data, we may find some pattern in terms of the price and supply change of resale houses, which make us a advantage in resale housing market.
 
  
To come up with the answers for the 3 problems above, the main variables and considerations we take into account in this project include:

Shares1.jpg


↑The picture above shows the shares of the resale public housing supply of town and flat type in 2005. It illustrates the quantity of resale public house in the edge of Singapore (like Tampines, Woodlands and others, nearly all of them are located in the end of the East West_Line or the top of the North_South Line) is large than other areas. As for the flat type, 3-5 rooms have the maximum supply, and are generally above 300.

Shares2.jpg


In the supply of the resale public house in Singapore, the floor area sqm from 60 to 120 is the majority. Too small and too large houses are not the main supply.

Price1.jpg


The Type S2 of 5 Room is most expensive, and its average resale price is already nearly S$1,000,000. Except for that, the resale prices of Terrace and Type S1 of 4 Room is also not easy to afford. Combined with the conclusions of shares, the optimal choice for customers who do not own very strong economic strength is to consider the Model A, Model A2, New Generation, Premium Apartment, Simplified and Standard of medium house.

Patterns of 2015 V.S. Patterns of the First-half of 2016

1516.jpg


There is no obvious differences in 2015 and the first half of 2016 on the resale price of various patterns. Only the price of multi_generation flat type in 2015 is a little higher than that in the first half of 2016.

Conclusion

  • The edge of Singapore has greater supply on the public house, especially the ends of West_East Line and the top of North_South Line. These areas have more residence communities, so the public housing supply is adequate.
  • The normal house owns the most supply quantity.
