Price Change

Home Value Map

This animated map of Real Estate property prices in the US, shows how home values have increased and changed since 2000.

Home prices were downloaded from Zillow Research. The values are calculated as an index. Fortunately, Zillow had data since 2000 to this year.

To show how the values progressed, the median of each year and each county were determined. Then the percentage of change was established.

Fuchsia shows decreasing values and green shows increasing values compared to the median.

During the first 10 years many counties have a -1% change. This is because there is no available Zillow data for them for that year, but there is, in later years. Nevertheless, until today out of 3,007 counties, 64 parishes, 19 organized boroughs, the data only includes 2844 counties, parishes and boroughs.

Below is a summary of the highest and lowest home values in the USA.

Real Estate Industry

The real estate industry is a business generating billions of dollars in revenue annually, and it offers many opportunities for entrepreneurs to turn a profit.

Last year there were approximately 210,000 companies operating in the residential brokerage and management field. They generated $200 billion in revenue.

There were 35,000 companies operating in the commercial brokerage and management field, generating $35 billion in revenue.

As displayed in this map Real Estate is a cyclical industry<, reacting to macroeconomic trends such as interest rates, population growth, and economic strength.

Real Estate soared in the post-World War II economic boom of the 1950s, sank in the inflation-riddled 1970s, rose again in the early 1980s until the depression at the end of that decade, and was prosperous again by the end of the century.

As it will be discussed below, low interest rates in the mid-2000s allowed residential Real Estate to boom even when the economy was slow - until the mortgage crisis hit, and prices collapsed. Source: Franchise Help

Housing Bubble 2008

This animation makes it possible to see the 2008 housing bubble. You can clearly see the rapid change in colors.

To make this even more clear and less distracting, there is a 0% change color to the counties that had no data. So counties with undefined% or 0% do not distract the viewer of the changes and trends. To know exactly which counties have missing values, you may hover over them. The data updates with the animation.

In the words of the Balance "The ultimate cause of the subprime mortgage crisis boils down to human greed and failed wisdom. The prime players were banks, hedge funds, investment houses, ratings agencies, homeowners, investors, and insurance companies."

"Banks lent, even to those who couldn’t afford loans. People borrowed to buy houses even if they couldn’t really afford them.

Investors created a demand for low premium MBS, which in turn increased demand for subprime mortgages. These were bundled in derivatives and sold as insured investments among financial traders and institutions."

"So when the housing market became saturated and interest rates started to rise, people defaulted on their loans which were bundled in derivatives. This was how the housing market crisis brought down the financial sector and caused the 2008 Great Recession."

Pandemic Real Estate

During the Pandemic Real Estate Prices increased dramatically in rural counties. Buyers sought homes in rural areas, searching for space to keep social distance.

Remote work also allowed people to seek larger homes with a home office.

This resulted in internal migrations that changed the Real Estate Market

Buyers with higher purchasing power from cities drove the prices in suburban areas.

Real Estate After the Pandemic

Disruptions caused by the supply chain pushed construction prices up. This in turn drove home prices to increase.

This has resulted in a volatile market. Some speculate that we are in a house market bubble. Time will tell......

Inspiration for a Property Value Map

I have always been interested in Real Estate prices and investment. I am not buying and selling property at the moment, but I definitely like to look at data related to it.

With this map I basically wanted to know: How Real Estate prices have changed? What are the housing market trends? Which are the most expensive areas to buy? Which areas are not prone to housing bubbles? Do Real Estate change the same in the East and in the West Coast? What are the Real Estate Prices near me?


Resources for Real Estate Map

The counties shapefile, to create this Choropleth map, was downloaded from the US Census Bureau.

The code to make an animated choropleth map, was altered from rfdonohue's block.

For this visualization I used the Zillow Home Value Index (ZHVI): "a smoothed, seasonally adjusted measure of the typical home value and market changes across a given region and housing type". They were downloaded from Zillow Research.
