2.2 Previous Research

2.2.1 Decision Making Factor to Purchase or Rent Residential Property

When renting or buying the house or room, there are many factor might be considered before the purchasing or renting. Gu, Liu, and Jia (2006) stated that customers will make decision based on the living steadily and value of house that is related to level of housing market. Some customers will think that certain housing lands can lead them from earning considerable profit in the future and consider whether it is worth to make investment to achieve in long-term profit or short-term profit.

Gu, Liu, and Jia (2006) said that the decision to purchase the house is based on economic capability that related to income of family. This is because if the price of the residence is increase, it may decrease the investment to the residences for low income family and especially to the young people.

In addition, Gu, Liu, and Jia (2006) also think that some customers might think that the housing price with rental ratio is not ideal for them and this also is a main factor for rental choice of customers. This is because housing price in market is directly related to the level of family income or payment.

Moreover, Takizawa, Yoshida, and Katoh (2007) said that the value of the house or some property is depends on that particular property's characteristic. Some of the price of a housing is depends on many factor such as seize area, occupied area of the house, facilities and others. 

Takizawa, Yoshida, and Katoh (2007) found that the room layout of a house can strongly affected the client decision for house rental. Customers will consider whether room or house's structure and style can fulfill their requirement.  For example, some of them may be unsatisfy about the position of the kitchen in the house or the parlor design of that particular house. Some of them might found that the housing environment is good enough but the house area is too wide for them.

Yu and Yu (2009) found that most of the rental market will rise on the start of the year that international students begin for their academic. Besides that, because of the rises of rental market, some of the residents are make investment to more houses property just wants to rent for others residents.

2.2.2 Notification System

Jeng and Drissi (2000) have developed Predictive Event Notification System (PENS) with two useful function that included Event Notification Service (ENS) and Event Prediction Service (EPS) to make successful to e-commerce market which is online transaction for selling or buying.

Jeng and Drissi (2000) said that Event Notification Service (ENS) allows buyers and sellers have real-time notification and the transaction between buyers and sellers that can be informed with the payment transaction and delivery time, ENS is related to publish / subscribe protocol. Besides that, Event Prediction Service (EPS) is used to meet customer's requirement in the future and e-commerce market direction which can be used to predict future products.

Furthermore, Kasai, Yamazaki, and Kurakake (2005) stated that notification system is essential to transfer information and update message through some devices. They created Novel Push-Style Notification System to transfer new information and this notification system can heighten the interest of users to find their desired information.

Kasai, Yamazaki, and Kurakake (2005) developed two different types of push-type notification system that are "Non-real Time Push" which will not make any alerts to the users for notification in real-time and "Real-time Push" which will make alert with sound in the real-time to make attention to users for receiving and reading the newly and useful information.

Beside this, Kasai, Yamazaki, and Kurakake (2005) have developed Notification User Model system to make sure that redundant message will not deliver at inappropriate time to users, which it have filtering function to eliminate unusable or not interested information. Moreover, Kasai, Yamazaki, and Kurakake (2005) also have created control mechanism to help users to find back their missed message with re-notification system. This mechanism can help them to make sure they can receive complete information.

2.3.9 Limitation of Current Home agent's website

There are some similarities for current available home agent's websites. Most of the rental or sales residential home page designs are is too dazzled or too complicated, so it is hard for customers to focus on where they should refer and where to search for their desired house or room. As a result, some of the users will feel irritable and maybe give up and leave that page as well.

Besides that, some of the home agent's website are lack with details information for the residential properties, it only shows the general information for customers to refer. If the home agent system does not have enough information, this will lower the client's confidence toward the system. Client will not be able to retrieve the information that they want. Therefore, these systems are proven to be fruitless to them. For example, customers cannot clearly know about what the furniture that will be provided by the house owner and the facilities that near to their house or room.

In addition, there are no photos provided for some rent or sales properties. Thus, client will not be able to see the big picture about the house's or room's condition. Moreover, they will also not able to know about the appearance of the properties.

Moreover, some of the features of the home agent's websites are redundant and have duplicate search results. In addition, irrelevant search results may lead to the wrong direction. Moreover, some of the links in the web page contain complicated function that lack of clearly procedure and user unfriendly interface so it might confuse customers.

Furthermore, some of rental or sales residence properties websites lack of SMS notification system. There are only Email contact for customers. So, this causes the two way communications between customers and agents or house owner become even difficult.

2.3.10 Improvement

Homepage website design is very essential to give first view impact to customers. It can be simple but must be in tidy form and provided useful and understandable features. So, this may allow customers have good impression on the website and will willing to search for their desired residential properties and this can save the time to find it out.

Beside this, photo of the property can be uploaded to the home agent system. To be even better, photo can be take from different angle and position to give more realistic condition's information to the potential tenant. This will raise customer's interest and clearer picture on that particular property to decide whether it is their desired house or room.

There must have good and clear categories about the types of property with house, room and apartment or flat and also categorize all of the possible states or places of that particular country to ease the customer to find out their desired room or house. With this, customers will save their time.

In addition, the system can provide procedure to login and register to the customers. This is because some of the customers may not familiar with it and may cause confusion.

Advanced search can be provided to customers to search for their desired properties. Some customers will not willing to read the information one by one about the rental or sales residential property.

Moreover, SMS notification system can be included to allow two way communications for house owners to leave the message through online to clients and vice versa. Beside this, Email address can be provided for contact purpose.

It also provides forum or specific function for customers to write their desired residential property information and can give their comment about home agent's service.

Easier to understand and use

More appropriate for small project

Feasibility StudyEasy to handle and manage

Requirements analysis and specification

Design and specification

Coding and module testing

Integration and system testing

Delivery and maintenance
