  1. NAR Data Analysis: A Beginner's Guide

Introduction

NAR (National Association of Realtors) data releases are a cornerstone of understanding the U.S. housing market. These reports, primarily focusing on existing-home sales, provide crucial insights into consumer behavior, economic health, and potential future market trends. Analyzing NAR data effectively can be highly valuable for investors, economists, real estate professionals, and anyone interested in the housing sector. This article will provide a comprehensive guide to NAR data analysis, covering the key reports, the metrics they contain, how to interpret them, and how to use this information for informed decision-making. We will also discuss the limitations of NAR data and how to supplement it with other sources. This article is geared towards beginners, assuming limited prior knowledge of real estate statistics.

Key NAR Reports

The NAR releases several reports each month, however, the most significant are:

  • Existing-Home Sales: This is the flagship report, released monthly, detailing sales of previously owned homes. It's arguably the most watched NAR report.
  • Pending Home Sales Index (PHSI): Released monthly, this index reflects signed contracts for existing-home sales, providing a leading indicator of future sales. A contract must be signed within the month to be included.
  • Housing Affordability Index: Measures whether a typical family can afford a median-priced home, based on income and mortgage rates.
  • NAR Realtor Confidence Index: A survey-based index reflecting Realtors' perceptions of the current and future housing market conditions.
  • Total Existing-Home Sales (TEHS): This report provides a complete view of all existing-home sales, including single-family homes, townhouses, condominiums and co-ops.

We will focus primarily on the Existing-Home Sales and Pending Home Sales Index reports for the purpose of this guide, as they provide the most comprehensive and frequently used data.

Understanding the Metrics in Existing-Home Sales

The Existing-Home Sales report is packed with data points. Here’s a breakdown of the most important metrics:

  • Total Existing-Home Sales (Seasonally Adjusted Annual Rate - SAAR): This is the headline number. It represents the number of homes sold in a month, extrapolated to an annual rate, adjusted for seasonal variations. **Seasonally Adjusted** data removes predictable fluctuations caused by factors like weather or holiday patterns, allowing for a clearer view of underlying trends. Understanding seasonal adjustments is critical.
  • Median Existing-Home Price: The price at which half of the homes sold for more and half sold for less. This is a more reliable measure than the average price, as the average price can be skewed by a few very expensive sales.
  • Year-over-Year (YoY) Price Appreciation: The percentage change in the median price compared to the same month in the previous year. This is a key indicator of price trends.
  • Months’ Supply: Calculated by dividing the number of homes for sale by the number of homes sold in a month. This indicates how long it would take to sell all current inventory at the current sales rate. A balanced market generally has around 6 months of supply. Less than 6 months favors sellers, while more than 6 months favors buyers. This is a vital measure of market equilibrium.
  • Inventory Levels: The total number of homes available for sale. Low inventory typically leads to higher prices, while high inventory can lead to price declines.
  • Days on Market: The average number of days a home stays on the market before being sold. Shorter days on market indicate strong demand.
  • First-Time Homebuyer Share: The percentage of homes purchased by first-time homebuyers. This is an important indicator of market health and accessibility.
  • All-Cash Sales Share: The percentage of homes purchased with cash. A higher percentage can indicate investor activity or a lack of mortgage availability.
  • Regional Sales Data: The report breaks down sales data by region (Northeast, Midwest, South, West), providing insights into local market conditions.

Interpreting the Pending Home Sales Index (PHSI)

The PHSI is a leading indicator because it reflects signed contracts, which typically close 30-60 days later. Here's how to interpret the PHSI:

  • Index Value: The PHSI is an index, with 100 being the base year (2001). Values above 100 indicate that sales activity is higher than in 2001, while values below 100 indicate lower activity.
  • Month-over-Month Change: The percentage change in the index from the previous month. This is a key indicator of short-term momentum.
  • Year-over-Year Change: The percentage change in the index compared to the same month in the previous year. This provides a broader perspective on the trend.
  • Correlation with Existing-Home Sales: The PHSI typically has a strong correlation with existing-home sales, meaning that increases in the PHSI often lead to increases in existing-home sales in the following months. However, the correlation isn't perfect. Correlation analysis is important to understand.

Using NAR Data for Decision-Making

Here's how different stakeholders can use NAR data:

  • Investors: Rising existing-home sales and a strong PHSI can signal a healthy economy and potentially benefit homebuilding stocks, mortgage lenders, and related industries. Declining sales can signal a slowdown and potentially create opportunities to short these sectors. Monitoring price appreciation and affordability is crucial for assessing the sustainability of the housing market. Consider value investing strategies.
  • Real Estate Professionals: NAR data helps Realtors understand local market conditions, adjust pricing strategies, and advise clients effectively. Knowing inventory levels and days on market can inform listing recommendations.
  • Economists: NAR data is a key component of economic analysis, providing insights into consumer confidence, wealth effects, and overall economic growth.
  • Policy Makers: Government agencies use NAR data to monitor housing market trends and develop policies to promote housing affordability and stability.

Combining NAR Data with Other Indicators

NAR data should not be analyzed in isolation. Here are some other indicators to consider:

  • Mortgage Rates: Changes in mortgage rates significantly impact housing affordability and demand. Track rates from sources like Freddie Mac.
  • New Home Sales: Data on new home sales, released by the Census Bureau, provides a complementary perspective on the housing market.
  • Construction Spending: Data on construction spending indicates the level of building activity.
  • Consumer Confidence: Consumer confidence levels influence housing demand.
  • GDP Growth: Overall economic growth impacts the housing market.
  • Unemployment Rate: Employment levels affect housing affordability and demand.
  • Population Growth: Population changes influence housing demand in specific regions.
  • Inflation Rate: Inflation impacts material costs, labor costs and overall affordability.
  • Personal Income: Income levels affect housing affordability.

Limitations of NAR Data

While valuable, NAR data has limitations:

  • Data Revisions: NAR often revises its data in subsequent months, so initial reports should be viewed with caution.
  • Sample Size: The data is based on a sample of transactions, not the entire market.
  • Geographic Coverage: The data may not fully reflect conditions in all local markets.
  • Seasonality: While seasonally adjusted, some seasonal variations may still be present.
  • Focus on Existing Homes: The Existing-Home Sales report doesn't cover new home sales, which can be a significant portion of the market in some areas.
  • Potential for Bias: The data is collected through Realtor surveys, which could introduce some bias.
  • Delayed Reporting: The data is released with a delay, meaning it may not reflect the very latest market conditions.
