Housing | Insight Maker

The housing market is heavily dependent on two main factors; supply and demand. Both play a major role in determining an equilibrium price for both sellers and buyers in the real estate market.

Residents, or the general population of individuals, place significant reliance on financial institutions to provide sources of capital i.e mortgages, to fund their purchases of homes. The rate of interest charged by these organisations in turn gives buyers (consumers) purchasing power, creating demand.

Supply is made up of the number of houses in the market, and consequently, of these, the number of houses which are up for sale. As the prices of houses for sale increases, the demand for purchase of these properties decreases. Conversely, the lower price, the higher the demand. Once the market reaches an equilibrium point, to which buyers and sellers form an agreement, houses are sold accordingly. An underlying factor to consider is the cost of construction, which impacts producers, or suppliers in this instance, and thus the number of homes for sale, and the expected profit sellers hope to achieve.

The simulated graph highlights the common scenario within the housing market, to which we see that as price increases, the total number for houses for sale decreases, generating an opposite slope to the price. As the price for houses increases, the demand for the houses decreases and vice versa. The equilibrium is evident at time 14 whereby the price of houses and the number of houses for sale overlaps which in turn creates a market to which both buyers and sellers are happy.

The Insight shown demonstrates how demand and supply in a real estate market can affect pricing.

Demand, Supply and Price have been represented by stocks. Each has an inflow where it has an increase in stock, and a corresponding outflow where stock is decreased.

Linking each stock and flow is a variable that changes that which it is linked to. These have been labelled appropriately. Each variable takes a decimal value and multiplies it with that it is linked to, such as the rate of demand affecting the price set as 0.001*Demand. This is to generate the loops required to show the rise and fall in price, demand and supply.

Adjustments can be made to the price, supply and demand stocks to simulate different scenarios. Price can be between 400 (400,000) and 1000 (1,000,000) in accordance to average housing prices. Demand and supply can be between 0 (0%) and 100 (100%), although having these set as realistic figures will demonstrate the simulation best.

Each simulation can be focused on how either demand and price interact over time or supply and price. These are shown in different tabs.

When the simulation is carried out, the way in which demand and supply rates affect pricing can be seen. Demand and supply are shown with price following shortly after with a slight delay, since changes in market behavior does not immediately affect prices of housing.

It should also be noted that the lines that represent each stock do not directly reflect the prices of housing in reality. Prices do not fluctuate so rapidly from 400 to near 0 like they do on the graph, however these are just representations of the interactions between each stock in a marketplace.

In the real-estate domain, buyers (demand) and sellers (supply) directly influence the price of houses. However, their motivation to buy and sell is directly influenced in respect to how the median price of houses is compared to the sensitivity (elasticity) of the actual prices and demand of houses.

This model will represent how the changes in price elasticity compared to the median price, affect the supply and demand within the real-estate domain.

1) Price and Demand Elasticity can be changed between 0-100 to show variances within the sensitivity of price in the market.

2) Buyers & Sellers are set to 75 however this can be fluctuated between 0-150 to represent variances within the demand & supply in the market.

3) Median Price is set to 75 since the total amount of buyers and sellers within the market is set to a maximum of 150. 75 is therefore the ‘median’.

4) Interest rates are also a factor in the demand of houses and influence the motivation for Buyers. If interest rates are high, Buyers are less motivated to buy due to increase in mortgages, therefore having a decrease in the demand and vice versa for when they are low. The following equation compares the price of houses to the median price, and if this condition is true, will apply Interest Rate(s) to the following logic.

if [Price]<[Median Price] Then

([Interest Rate]+[Demand Growth Ratio]-[Demand Growth Ratio])*[Buyers] end if

5) The price of houses is directly influenced by elasticity of demand and price within the market place. For example; if the elasticity of demand is relatively inelastic, the percentage change in the amount of houses demanded is smaller than that of the price. The following equation applies the logic listed above.

60-[Supply Elasticity of Price]/100*[Total Sellers]+[Demand Elasticity of Price]/100*[Total Buyers]+[Price Elasticity of Supply]/100*[Total Sellers]

The law of supply and demand is a basic economic principle that explains the relationship between supply and demand for a good or service and how the interaction affects the price of that good or service. The relationship of supply and demand affects the housing market and the price of a house.

A number of factors including government policy affects the law of demand and supply, which I hope my diagram illustrates

When there is a high demand for properties in a particular city or state and a lack of supply of good quality properties, the prices of houses tend to rise. When there is no demand for housing due to a weak economy and an oversupply of properties is available, the prices of houses tend to fall.

The following model shows a real estate market created by a web-based modelling and simulation tool; Insight Maker. This model shows the relationships and links between many different players within the real estate market and how some changes are able to change the marketplace overall.

Information from Model

The information generated from this model includes "Wanting to Buy", "Houses for Sale" and "Price". "Wanting to Buy" refers to the players who demand or wish to buy houses, "Houses for Sale" refers to the total supply of houses within this marketplace whilst "Price" refers to the price an individual bought a house at a certain point in time.

Variables Included

All variables on the model are shown as ovals and are either fixed or can be adjusted. The fixed variables are shown in yellow, where fixed refers to not being able to be changed by non-editors viewing this model. These variables can not be adjusted as these variables are directly related from the information produced within the model. For example, the variable "Price" can not be adjusted as it would produce incorrect information when the model is simulated

All other variables shown in orange can be adjusted by moving the respective sliders. These variables are able to be adjusted according to what the view wishes.

Interesting Parameters

One adjusted that the user can make is to increase the "Demand Elasticity of Price" from 100 to 200. This increase in demand elasticity means a greater amount of individuals would be willing to purchases a house. As with the laws of supply and demand, an increase in demand will lead to a increase in price. Once simulated, this model shows that over time the price for a house increases.

One other interesting parameter that the user could do is to increase the level of "Destroy Houses" from 0.05 to 0.1. This increase would lead to a fall in the total amount of houses as the level of houses being destroyed (0.1) is greater than the level of houses being build (0.05). As shown in the simulation, this would lead to a fall in the total houses available in the marketplace.

This is a 3 year model that depicts the flows between Price, Supply and Demand in the real-estate market.

Throughout the model viewers can observe how the figures Price, Supply and Demand alter each other in an increasing or decreasing way.

Price is decreased by the growing supply of HousesForSale and increased by the growing demand of people wanting to buy. As Price decreases, HousesForSale increases and Price decreases as HousesForSale increase.

From the use of the graph it is evident that over 3 years the flow of house prices fluctuate and therefore more houses are sold at different times over 3 years.

The purpose of this insight is to help consumers and Businesses depict the best times to either buy or sell houses to maximize profits.

Additionally the market had to respect the number of possible consumers who are opting to build new houses, based on the rise and fall of house prices the real-estate analyses the new houses and residents in the area grow overtime.

Due to population growth, This cycle remains continuous so long as the real-estate company manages their resources effectively

Retail Re-state Market

Insight Maker is a program that allows users to create complex interactions among industry or social factors. This program was used to model the relationships among different players in the real estate market.

This model shows the effects of changes in supply and demand, demand price and supply cost, availability of houses and houses prices on the Retail Re-state Market. Each simulation can be focused on how either Demand, Supply, supply cost, demand price, interest rate and availability of houses interacts with one another over time.

Demand, Demand Price, Supply, Supply Cost, Interest Rate, House Market and Houses Prices can be all adjusted by the user using the sliders [Slider Value 0-100 (000 000 value)] except for interest rate where it limited to 0-0.10. Allowing the user to simulate different scenarios and view changes in the market.

For Example: A slight change in House Prices will affect the Availability of Houses, House Price and the Supply and Demand dramatically.

When Supply increases, the availability of houses increases while Demand decreases.

Fixed variables/relationships:

Buyer Growth Rate, the Demand Price, Price Demand, Price Decrease, Supply Rate, Supply Price, Price Supply, Price Decrease.

These variables/relationships are shown on yellow. Fixed refers to no adjustments or changes is allow to those specific variables/relationships by the non -editor viewer. These variables cannot be change or adjusted as these variables/relationships are directly related to the information produced. With any changes to the fixed variables/relationships, it can cause incorrect simulation of the model to viewers.

Supply/Supply Cost has a direct relationship to one another as one variable increases the other one decreases. Demand and Demand Price has an inversely relationship related to Price.

House Price is the main reason why someone would sell or buy a house. Price is made up of various different factors. Demand price, demand, supply cost and supply are the main reasons houses price fluctuates.

Availability of Houses is simply New houses and houses Sold, based on If statements, If Demand=>Supply or If Supply <= Demand, the quantity will adjusted to meet the Demand and Supply levels.

Houses Price is simply House Price Increase and Houses Price decrease, based on if statements, If Demand=>Supply Cost or If Supply Cost <= Demand Price, the price will be adjusted to meet the Demand and Supply price.

Interesting Parameter:

This point is interesting because it shows greatest fluctuations. You will see in Price Impact on Demand/Supply display when house prices increases, supply will increase while demand will decrease, as people are less willing to purchase a house at that price due to high cost vice versa. Market availability and prices, as availability of houses increases there is a decrease in houses prices causing excess of supply, leading to an increase in demand as people are more willing to purchase properties when prices are lower vice versa. Construction shows availability of new houses, over time houses are sold, when sold houses hits zero, new houses will increase as there will be a deficient of supply vice versa.

Setting Demand at 100

Setting Demand Price at 100

Supply at 50

Supply Cost 60

Availability of Houses 100

House Prices 85

Interest Rate 0.05

Notes:

There is a slight delay when a change variable is changed in this model. This represents the real market as a change in price, demand or supply doesn’t translate to an immediate action on the market as shown by this model.

This diagram implies the simple supply and demand concept to show the relationship of different roles in the real estate market and how they affect the price of houses, buyers and sellers.

The motivations are based on the concept, when the houses’ price goes down (demand goes down) there will be more people interested in buy a new house (supply goes up).

The simulation will show the range within 36 months as units. It demonstrates the comparison of price, houses buyers and Houses for sale.
