Part 2 of 3
In the ever-changing landscape of real estate markets, international
consultants and analysts face the challenge of navigating complex data sets to
provide valuable insights for their clients. Traditional ranking systems often
rely on standard metrics to evaluate the performance of different countries,
but these methods may not fully capture the nuances and outliers that can
significantly impact investment decisions.
Innovative data-driven methodologies, such as effect coding, offer
a fresh perspective for re-evaluating and challenging traditional rankings.
This approach provides a deeper understanding of how different countries
perform in real estate. For international consultants and analysts looking for
a more nuanced method of analyzing real estate markets, the application of
effect coding can be transformative.

Interpretation
of the Data
International consultants and analysts can
interpret the above data from Numbeo for their expat retiree clients who prefer
renting instead of buying and for foreign investors who favor lower property
prices and higher rental yields.
1.
For
Expats who prefer stretching their finances:
- Countries
with higher Gross Rental Yields (GRY), such as UAE, Mexico, UAE, and Spain,
might be more attractive for hybrid living (living and generating rental
income) as they offer a higher return on investment through rental income
compared to other countries on the list.
- Expats
may consider countries with lower Property Price to Rent (PPR) ratios,
such as Mexico, Spain, and UAE, as this indicates that renting is
relatively more affordable in these countries than buying a property.
- Lower
Mortgage to Income (MI) ratios, such as those in UAE, Spain, Japan, and
Switzerland, indicate that expats can manage mortgage payments (if they
qualify) more comfortably without stretching their finances.
2.
For
Foreign Investors who prefer lower property prices and higher rental yields:
- Countries
with lower Property Price to Income (PPI) ratios, such as UAE, Spain,
Australia, and New Zealand, may present good investment opportunities for
those looking for lower property prices relative to income levels in the
country.
- Higher
Gross Rental Yields (GRY) in countries like UAE, Mexico, and Spain suggest
the potential for higher rental income in proportion to the property
price, making them attractive for investors looking for good rental
yields.
- Countries
with lower Property Price to Rent (PPR) ratios, such as UAE, Mexico,
Spain, Brazil, and Chile, may offer foreign investors the opportunity to
acquire properties at lower prices relative to rental income potential.
In summary, expat retiree clients and foreign
investors can benefit from analyzing the Property Price to Income, Gross Rental
Yield, Property Price to Rent, and Mortgage to Income ratios in each country to
make informed decisions based on their preferences for renting, buying,
property prices, and rental yields.
Understanding
Effect Coding
Effect coding is
a statistical technique that centers and balances data around the overall
average. This method allows for a more straightforward interpretation of the effects
of different variables. Specifically, the effect-coded index ranks countries
based on their average deviations from the overall average deviation. Countries
with positive deviations (those above the average) receive a higher rank,
whereas countries with negative deviations (those below the average) receive a
lower rank.
In this analysis,
the average deviations in Property Price to Income (PPI), Gross Rental Yield
(GRY), Property Price to Rent (PPR), and Mortgage to Income (MI) will be
effect-coded to create an effect-coded index and to re-rank the countries
accordingly.
Effect coding can
serve as a robust, data-driven approach to challenge traditional indexing
methods, depending on the specific goals and assumptions of the analysis. This
technique highlights countries that significantly deviate from the average,
either positively or negatively. As a result, it proves helpful in identifying
countries with exceptional performance as well as those that are significantly
underperforming.
Economic
Significance
The economic significance of effect coding in
this context depends on the interpretation of the underlying data and the
specific questions being asked. Here are some potential interpretations:
Identifying Outliers: Countries with high effect-coded index values might be considered outliers regarding their property market dynamics. This could indicate unique economic conditions, policy interventions, or other factors driving their deviation from the average.
Identifying Potential Risks: Countries with large negative deviations might face economic challenges or property market instability. This information can be valuable for investors and policymakers.
It is important to note that effect coding has
some limitations:
·
Sensitivity
to Outliers:
The effect-coded index can be sensitive to outliers, as a single country with a
substantial deviation can significantly impact the overall ranking.
·
Loss
of Information:
By focusing on deviations from the average, effect coding might overlook other
important aspects of the property market, such as the absolute level of prices
or rental yields.
Effect-Coding
to Create A Challenger Index
1. Comparison and Prioritization: International consultants can more effectively compare the deviations in key metrics across countries using effect coding. The effect-coded Index provides a new rank order that can challenge
the traditional ranking and offer a fresh perspective on which countries excel
in different aspects.
2. Identification of
Opportunities:
The effect-coded data can help identify countries that may have been overlooked
in traditional rankings but offer significant opportunities based on
their average deviations. For example, several countries moving up in rank
based on their effect-coded indices signal potential client opportunities
regarding property investments or rental considerations.
3. Tailored Recommendations: International consultants can provide more tailored recommendations to their clients based on the effect-coded data. For
expat retiree clients, consultants can identify countries with more favorable
deviations regarding rental affordability or Income to Property Price ratios.
For foreign investors, countries with higher deviations in rental yields or
lower property prices relative to income could be highlighted for
consideration.
4. Risk Assessment: The effect-coded data can also help
assess risk factors. Countries with high deviations in Mortgage to Income ratios
or property price affordability may indicate greater risks for investors or
expats, and consultants can advise clients accordingly.
In summary,
effect coding can be a valuable tool for international consultants and analysts
to challenge traditional indices, provide fresh insights, and offer more
tailored advice to expat retiree clients and foreign investors based on a
deeper analysis of key property market metrics deviations.

Analysis
of Effect-Coded Ranking
The changes in rankings of countries after effect
coding, such as Canada and New Zealand rising while Japan and Switzerland
declining, can be explained by the impact of the average deviations in key
metrics on the effect-coded Index. International consultants and analysts can
interpret these switches to their expat retiree and investor clients in the
following ways:
1.
Canada
and New Zealand rising in ranking:
- Canada
and New Zealand may have seen improvements in their rankings due to more
favorable average deviations in metrics such as Property Price to Income
(PPI), Property Price to Rent (PPR), Gross Rental Yield (GRY), or Mortgage
to Income (MI) after effect coding.
- International
consultants can highlight these countries to their expat clients as
potentially more attractive destinations for renting or investing based on
their improved positions in the re-ranking.
- For
investor clients, the rise in rankings of Canada and New Zealand could
indicate better opportunities for property investments, with potentially
higher rental yields or more affordable property prices compared to other
countries.
2.
Japan
and Switzerland declining in ranking:
- After
effect coding, Japan and Switzerland may have experienced lower rankings
due to less favorable average deviations, such as in Property Price to
Income (PPI), GRY, PPR, or MI.
- International
consultants can explain to their retiree clients that, based on their
lower positions in the re-ranking, these countries might not offer as
competitive rental affordability or property market conditions as
previously thought.
- For
investor clients, the decline in rankings of Japan and Switzerland may
suggest potential challenges or risks regarding property investment
returns, affordability, or market dynamics that should be considered
before making investment decisions.
In interpreting these switches to their clients,
international consultants and analysts should consider the specific preferences
and requirements of their expat retiree and investor clients. Recommendations
can be tailored based on the changes in rankings, providing insights into the
potential benefits and drawbacks of considering countries that have moved up or
down in the re-ranking after effect coding. This proactive approach can help
clients make more informed decisions aligned with their goals and preferences
regarding renting, buying, and investing in international real estate markets.
Highest
and Lowest Effect-Coded Values
The extreme effect-coded values for Brazil and
the UAE can be explained by the specific deviations in key metrics for each
country and their impact on the effect-coded index. Here is an economic
explanation for these two extreme values:
1.
Brazil
(Effect-Coded Value: 118.43):
- Despite
having the highest Mortgage to Income ratio (199.70) and the
second-highest Property Price to Income ratio (16.30) in the dataset,
Brazil still achieved a very high effect-coded value (118.43).
- This
indicates that Brazil's overall performance in other key metrics like
Gross Rental Yield (GRY) or Property Price To Rent (PPR) may have been
robust, contributing to its high effect-coded value.
- The
high effect-coded value implies that despite the high Property Price to Income and Mortgage to Income ratios, Brazil remains an attractive
destination for investment or renting based on other positive market
dynamics.
2.
UAE
(Effect-Coded Value: -70.37):
- Despite
having the lowest Mortgage to Income ratio (29.10) and the second-lowest
Property Price to Income ratio (3.90) in the dataset, the UAE obtained a
very low effect-coded value (-70.37).
- This
suggests that the UAE's performance in metrics like Gross Rental Yield
(GRY) or Property Price to Rent (PPR) may have significantly deviated from
the average.
- The
low effect-coded value indicates that despite favorable mortgage and
property price to income ratios, the overall property market conditions in
the UAE may present challenges or risks that influenced its ranking.
In evaluating the economic explanations for
the extreme effect-coded values of Brazil and the UAE, it appears that the
broader market dynamics captured in the effect-coded index play a significant
role in determining their positions. International consultants and analysts can
use these insights to offer more comprehensive advice to their clients,
considering the nuanced relationships between various property market metrics
in each country.
Conclusion
In conclusion, traditional ranking systems in real estate analysis
may be limited in capturing the nuances and outliers that affect investment
decisions for international consultants and analysts. By harnessing the power
of innovative data-driven methodologies like effect coding, international consultants
and analysts can gain a deeper understanding of how countries stack up in terms
of property market metrics.
Challenging traditional rankings and identifying outliers through
effect coding offers a more comprehensive and nuanced view of real estate
markets, enabling international consultants and analysts to provide richer
