18 hour city

What Is 18-Hour City?

An 18-Hour City is a mid-sized metropolitan area characterized by a vibrant economy, attractive amenities, and a lower cost of living and business compared to larger urban centers, often referred to as "24-hour cities." These cities typically offer public services, entertainment, and job opportunities that are comparable to major hubs, but do not operate on a constant 24-hour cycle. The concept of an 18-Hour City falls under the broader category of Real Estate Investment, specifically focusing on urban development and market potential. They are seen as attractive alternatives for residents seeking a balance between urban dynamism and livability, and for investors looking for growth potential outside of the most expensive primary markets.61

History and Origin

The term "18-Hour City" was jointly coined in 2015 by the non-profit Urban Land Institute (ULI) and consulting firm PwC.60 It emerged from their annual survey of real estate markets, "Emerging Trends in Real Estate," to describe cities identified as attractive investment opportunities due to their affordability and potential for future growth.59 The label evokes the idea that while these cities are bustling and active for a significant portion of the day, their pace winds down more than larger, continuously active "24-hour cities."58,57 This concept gained prominence as a significant market trend in commercial real estate, highlighting the shift of residents and businesses to more affordable yet dynamic urban environments.56 The Urban Land Institute continues to publish its "Emerging Trends in Real Estate" report annually, providing insights into real estate investment and development trends, with its 2024 report focusing on a "Great Reset" in the industry.55,54,53

Key Takeaways

  • An 18-Hour City is a mid-sized urban area with a thriving economy, growing population, and diverse amenities, but generally lower costs than larger "24-hour cities.",52
  • These cities are characterized by strong population growth, expanding job markets, and a quality of life that attracts both residents and businesses.,51
  • They are viewed as appealing for real estate and commercial investment opportunities due to their potential for above-average returns and lower entry costs compared to primary markets.50,49
  • While offering robust economic opportunities, they maintain a more relaxed pace and reduced congestion than major metropolises.48
  • Examples include cities like Austin, Nashville, Charlotte, Denver, and Raleigh.47,46

Formula and Calculation

The concept of an 18-Hour City does not involve a specific financial formula or calculation in the traditional sense. It is a qualitative designation based on a combination of urban characteristics and economic indicators. However, real estate investors evaluate these cities using various metrics that contribute to their appeal:

  • Capitalization Rate (Cap Rate): This metric helps estimate the potential return on investment for income-producing properties. While not unique to 18-Hour Cities, these markets often feature favorable cap rates. Cap Rate=Net Operating IncomeCurrent Market Value\text{Cap Rate} = \frac{\text{Net Operating Income}}{\text{Current Market Value}}
  • Population Growth Rate: A key indicator, often measured as an annual percentage change, reflecting the influx of new residents.,45
  • Job Growth Rate: Measures the annual percentage increase in employment within the city, indicating economic vitality.44,43
  • Vacancy Rates: Low real estate vacancy rates across residential and commercial real estate sectors suggest strong demand.

Interpreting the 18-Hour City

An 18-Hour City signifies a dynamic urban environment that balances the extensive amenities and job opportunities of a major metropolitan area with a more manageable pace and lower costs. Investors interpret the "18-hour" designation as an indication of significant growth potential without the saturation and prohibitive expenses often found in "24-hour cities."42,41 These cities attract a diverse demographic, including millennials and young professionals, drawn by career prospects and a high quality of life.40,39

From an urban planning perspective, the emergence of 18-Hour Cities highlights a shift towards sustainable urban development that prioritizes livability alongside economic growth.38 The presence of well-developed infrastructure, public transportation, and diverse lifestyle offerings further supports their appeal.37

Hypothetical Example

Imagine a real estate developer, "Urban Growth Ventures," is looking for new investment opportunities. They analyze various cities based on the characteristics of an 18-Hour City.

Urban Growth Ventures identifies "Midville," a city with a population of 700,000, as a potential 18-Hour City. Over the past five years, Midville has seen an average annual population growth of 2.5%, significantly higher than the national average. Its job market has expanded with new tech companies opening offices, leading to a 3% annual increase in employment. The cost of living in Midville is 30% lower than in nearby major cities, making housing affordability attractive to young professionals.

The developer notes that Midville's downtown area has undergone revitalization, with new restaurants, cultural venues, and mixed-use developments emerging. While not operating around the clock like a 24-hour city, many businesses, including eateries and entertainment spots, remain open until late evening. The average capitalization rate for multifamily properties in Midville is 6.5%, offering a more attractive return on investment compared to the 4% seen in primary markets. Based on these indicators, Urban Growth Ventures decides to invest in a new residential complex in Midville, anticipating continued growth and strong demand.

    25#24#23 Limitations and Criticisms

While 18-Hour Cities present compelling investment opportunities, they also come with limitations and potential criticisms. The primary assumption when investing in an 18-Hour City is that its market and property values will continue to expand, eventually resembling the elevated values seen in larger 24-Hour Cities. However, there is no guarantee that this will occur. A city's growth could slow or even stagnate, making it challenging to achieve the desired return on investment.,

C22r21itics also point out that the loosely defined nature of an 18-Hour City can lead to broad interpretations, and not all mid-sized cities will experience the same trajectory of economic growth. Factors such as unforeseen economic downturns, shifts in demographic trends, or inadequate infrastructure development could hinder their progress. Rapid urban development in these cities can also strain existing infrastructure and lead to increased traffic congestion, potentially impacting the quality of life for residents and deterring future population growth. Fur20thermore, unlike major financial hubs, these cities may not have the same depth of established businesses and specialized services, which could limit certain types of large-scale commercial real estate investment.
