Real Estate Market Modeling diagram

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.

Real Estate Marketplace

The model shown provides a visual representation of the processes that occur when Buyers (Demand), the Sale of Homes (Supply) as well as Price interact when it comes to the Real Estate Marketplace.

Price is the main factor that ultimately influences the movement of both supply and demand within the real estate marketplace. Those considering purchasing a new home will be influenced to buy when prices are lower than that of the median price whereas sellers prefer to sell their homes higher than the median price in order to make a higher return.

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.

Shown here is a diagram of a Real Estate Market where in which variables like price, supply and demand are found to be present and play a role in the sides of the buyers and the sellers.

When prices go up the supply of sellers increase while the demand of buyers decrease. When prices go down the supply of buyers increase in the real estate market while the demand of sellers decreases.

It is the simple economic rule found in plain sight in the real estate market.

1 - Price elasticity of Supply with the sellers is high due to their ability to adapt to sudden changes in prices in the market.

2 - Demand elasticity of price on the other hand was not proven to be as high in the calculations since there was no factual data as to how fast the buyers reacted to an increase in supply or a decrease in price. Although seen is the increase in demand when a the price is lowered.

3 - Increases in Median Price lead to a increased Supply from the Sellers.

4 - Decrease in Median Price lead to a increased demand from the Buyers.

The real estate market is heavily influenced by social and economical factors that effect the price of dwellings. Two of the main factors that contribute to not only the housing market but most consumables are supply and demand.

Supply is the amount of one good or service in that market. A market driven economy could utilize supply to regulate price. Generally, if the supply is higher than the demand for that good the price will be lower. If the supply is lower than the demand, the price will tend to increase.

Demand is the amount of consumers that want/need that good or service. Price is also influenced by demand. Generally, if the demand is higher than the supply the price will increase. If the demand is lower than the supply, the price tends to decrease.

Price can be derived from demand and supply.

The following model depicts how the changes in supply and demand of Households effect pricing. The sliders replicate how each of the variables interact with price.

Secondary factors, such as interest rate, foreign investors and government policies also all weigh in on determining a price for a dwelling.

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.

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

The purpose of this model is to provide users with an understanding of the relationships among different players in a real estate marketplace. The main focus of this model is on Demand, Supply & Prices in the period of 3 years(36 months).

Key players of the real estate marketplace includes investors, 1st homebuyers, banks, governments, housing developers and real estate agents. This model is designed in a real estate agent perspective, therefore, it is not included in the model.

In the real estate marketplace, HousingPrices can be affected by InterestRate, HousesForSale(Supply), WantingToBuy(Demand) and ConstructionCost.
The Motivation for Demand can be affect by InterestRate. Demand for housing can be affected by HousingPrice and so is the supply for housing.

Change the variables below using the sliders or input the value you want and see how it affects the simulation.

When ConstructionCost is high, less Profit received and vice versa.
When InterestRate is high, Motivation decrease-->Demand decrease and vice versa.
Having longer or shorter SalesTime can affect SalesRatio which can affect increase/decrease of Sales.
Having high/low initial amount of housing can affect HousesToMarket-->HousesForSale-->
DesiredSales-->SalesRatio.

FONDO:

El siguiente modelo de simulación demuestra la relación entre la oferta, la demanda y los precios dentro del mundo valoración de nuevos productos generados en base al capital del conocimiento o productos de base tecnológica. He basado el modelo en una ciudad pequeña con una población de 100,000 residentes a partir de 2015.

EJE:

X-Axis

El X-Axis muestra el tiempo. Comienza en 2015 en el mes de octubre y continúa durante 36 años consecutivos.

Eje Y

Hay 2 ejes Y en este modelo. El lado izquierdo se relaciona con el precio, la demanda y el suministro, mientras que el lado derecho solo enumera la población.

Como se puede ver, esta ciudad tiene una población de 100,000 residentes hasta la fecha. La parte inferior del modelo muestra un bucle de población que produce una tasa de crecimiento exponencial del 2.5%. Esta ciudad dinámica y en crecimiento puebla aproximadamente a 240,000 residentes después de 36 años.

MODELO

El modelo consta de 2 carpetas llamadas: Compradores / Consumidores y Proveedores / Productores. Esta primera carpeta representa la 'Demanda'. Incluye una tasa de crecimiento de compradores, aumento y disminución de interés de los compradores, una demanda de precio y el precio de demanda. Las fórmulas forman un aumento exponencial de la demanda debido al rápido y continuo aumento de la población en este mercado. A medida que la población aumenta, también lo hace la demanda de los compradores.

La segunda carpeta transporta el suministro de nuevos productos de base tecnológica generados en centros de I+D . Incluye un bucle sofisticado de bienes inmuebles. La población que posee productos de base tecnológica en el mercado deciden vender o consumir el producto de base tecnológica . Esto se convierte en las productos de base tecnológica en venta. Estos nuevos productos de base tecnológica se venden y los nuevos productos vendidos vuelven a entrar al mercado y el ciclo continúa.

El suministro tiene una relación inversa con el precio. Cuando los precios bajan, los suministros bajan porque la demanda aumenta. Y cuando el precio sube, también lo hace el suministro. Esto representará el crecimiento de nuevas productos en el mercado.

PRECIO Nota: El precio se basa en las tarifas de alquiler mensual. El precio depende de muchas variables. Lo más importante es la oferta y la demanda. También incluye factores tales como las expectativas y el valor económico de la casa. He incluido un valor económico estable, 'bueno' para todos los hogares ya que esta ciudad ficticia se encuentra en un área estable y en crecimiento. El precio fluctúa durante toda la simulación, sin embargo, también sube de precio. Con el paso de los años, las casas siguen subiendo de precio mientras fluctúan regularmente. Por ejemplo, en 2018 (3 años después), el precio máximo para una casa fue: $ 4254.7 y el precio mínimo fue de $ 852.98. Por otro lado, en octubre de 2051 (36 años después), el precio máximo fue: $ 14906 y el precio mínimo fue de $ 7661. (Esto se basa en los siguientes datos: Casas en Venta: 500, productos nuevos de base tecnológica que han vendido: 100, Casas en el Mercado: 730).

SLIDERS

There are 3 sliders on the bottom that could be altered. The simulation would react accordingly. The 3 sliders include changeable data on:

- Houses for Sale.

- Houses that have Sold.

- Houses in the Market.

Hay 3 controles deslizantes en la parte inferior que se pueden modificar. La simulación reaccionaría en consecuencia. Los 3 controles deslizantes incluyen datos modificables en:- Nuevos productos en venta.- Productos de base tecnológica que han vendido.- productos de base tecnológica en el mercado.

BACKGROUND:

The following simulation model demonstrates the relationship between supply, demand and pricing within the real estate and housing world. I have based the model on a small city with a population of 100,000 residents as of 2015.

AXIS:

X-Axis

The X-Axis shows the time. It begins in 2015 in the month of October and continues for 36 consecutive years.

Y-Axis

There are 2 Y-Axis on this model. The left hand side relates to the price, demand, and supply, while the right hand side solely lists the population.

As you could see, this town has a population of 100,000 residents to-date. The bottom of the model shows a population loop that produces an exponential growth rate of 2.5%. This dynamic and growing city populates approximately 240,000 residents after 36 years.

MODEL

The model consists of 2 folders named: Buyers/Consumers & Suppliers/Producers. This first folder represents the 'Demand'. It includes a buyers growth rate, buyers interest increase and decrease, a price demand and the demand price. The formulas form an exponential rise in demand due to the rapid and continuous increase in population in this new city. As population increases, so does the demand from buyers.

The second folder conveys the supply of houses. It includes a sophisticated loop of real estate. Residents who own houses in the market decide to sell the home. This becomes the Houses for sale, also known as the 'supply'. Those houses are sold and the sold houses re-enter the market and the loop continues.

The supply has an inverse relationship with the price. When prices drop, supplies drop because the demand goes up. And when the price goes up, so does the supply. This will represent the growth of new houses in the market.

PRICE

Note: The price is based on monthly rent rates.

The price is dependant on many variables. Most importantly, the supply and demand. It also includes factors such as expectations & the economic value of the house. I have included a stable, 'good' economic value for all homes as this fictional town is in a stable and growing area.

Price fluctuates throughout the entire simulation, however it also goes up in price. Over the years houses continue to rise in price while they regularly fluctuate. For example, in 2018 (3 years later), the max price for a home was: $4254.7 and min price was: $852.98. On the other hand, in October 2051 (36 years later), the max price was: $14906 and the min price was: $7661. (This is based on the following data: Houses for Sale: 500, Houses that have sold: 100, Houses in the Market: 730).

SLIDERS

There are 3 sliders on the bottom that could be altered. The simulation would react accordingly. The 3 sliders include changeable data on:

- Houses for Sale.

- Houses that have Sold.

- Houses in the Market.
