Troostwijk Index Q4 2026

Construction and business inventory costs continued to rise in the fourth quarter of 2026.

Highlights:

- The **Troostwijk Index** reached **142.6 points for business buildings and offices, 139.1 points for residential construction and 141.2 points for business inventory**, reflecting continued cost inflation across all categories.
- On a year-on-year basis, **business inventory recorded the strongest growth (+6.6%)**, followed by **business buildings and offices (+4.7%)** and **residential construction (+4.4%)**, highlighting persistent inflationary pressures throughout the sector.
- **Construction costs** increased by **1.3% quarter-on-quarter for business buildings and offices** and **0.7% for residential construction**, driven by ongoing labour shortages, wage inflation and limited contractor capacity.
- **Building material prices** generally trended upwards. **Steel, cement, glass and paint** recorded price increases, while **bitumen, sand and plastic products** saw the strongest rises. Bricks remained broadly stable.
- **Business inventory costs** rose by **1.1% during the quarter**, supported by higher labour costs, continued shortages in the labour market, rising technology and machinery component costs, and sustained pressure on raw material prices.
- **Geopolitical tensions, trade measures and supply chain risks** continue to influence commodity and energy markets. Troostwijk expects inflationary pressures to persist into 2027, with energy prices remaining volatile, metal prices continuing to rise and wage growth remaining elevated.
- This maintains the cautiously inflationary outlook presented in previous quarters, with cost increases expected to continue across construction and business inventory throughout 2027.

The state of energy efficiency 2026 report

Developed by **Accumin’s Department of Studies & Research**, the **State of energy efficiency 2026 in Spain report** provides a statistical analysis of the energy performance across the residential housing market and identifies the scale of transformation required to improve efficiency. 

Key highlights include: 

- **94.2% of the housing stock is estimated to be energy inefficient**, underlining the magnitude of the transition challenge. 
- **Energy renovations can reduce energy consumption** by up to 75% in most single-family homes and by up to 50% in multi-family buildings. 
- **Renovation of the existing housing stock** remains an **essential element** to achieve decarbonisation objectives, given the structural gap between the existent stock and new-build housing. 

The report finds that the current pace of energy-efficient renovation and improvement activity is unlikely to be sufficient to significantly transform the residential sector by 2030 and meet the expected goals. 

Understanding the current state of the residential market and where the main challenges and opportunities lie is critical to identify renovation potential and support informed decision-making throughout the transition towards an energy-efficient housing sector.

Hidden costs and opportunities: Persch Consult by Accumin Whitepaper

Newsroom 20260909 opt.jpg

For many credit institutions, the determination of the mortgage lending value appears to be a well-managed mandatory process; in reality, however, it is often a hidden burden in the mortgage business. 

**Christian Schuhmann MRICS, Managing Director at Persch Consult by Accumin**, has developed a report that includes a profound examination of what the challenges are and why optimising these areas is important.

This study addresses the four possible target architectures for banks, evaluates them and highlights the urgent need for action..

Key takeaways

- Valuation can be used as the key lever in the mortgage business.
- It is not possible to make an assessment simply by looking at internal FTE capacity or external supplier prices.
- Regulatory safety and quality must be firmly embedded as system characteristics.
- Standardisation, governance, scalability and automatization can improve efficiency while maintaining quality and required compliance.

Spain’s coastal residential market continues to show strong drive in 2026, supported by limited housing supply and sustained tourism activity. The market remains heavily influenced by the second-home sector, which continues shaping prices, development and therefore, affordability across the main coastal destinations. 

Most notable findings: 
- **Coastal residential prices** accelerated by **13.5% year-on-year**, placing the average value at 2,223€/m2
- Housing affordability continues to deteriorate, with the **average purchase effort reaching 40%** of household disposable income, compared with 34% nationally
- New-build activity was potentiated, with **residential permits increasing 21.7% year-on-year**, although supply remains insufficient
- The holiday housing segment continues to strengthen its influence
- **International demand remains a key market driver**

The study highlights how supply shortages, demand based on tourism and the growing weight of second-home market are shaping the Spanish coastal housing landscape. These trends continue to reinforce regional disparities while presenting challenges for housing accessibility and long-term market balance.

Chile Incoin report 2Q 2026

Newsroom 20261014 01.jpg

The latest Incoin report studies Chile’s metropolitan region, where it records a recovery in the housing market for the second quarter of 2026. A total of **4,863 homes were sold**, representing a **1.7% increase** compared to the previous quarter, although activity remains 4.5% below Q2 2025 levels. The recovery has been driven primarily by improved financing conditions and strong demand for homes with immediate delivery. 

Demand continues to concentrate in the most accessible market segments. Homes valued below **4,000 UF accounted for nearly 65% of sales**, while the mortgage-rate subsidy has helped accelerate purchasing decisions and reduce available inventory. 

Looking ahead, the report suggests that sustained financing conditions and continued absorption of existing stock could support the launch of new residential projects across the metropolitan region.

Troostwijk Index Q3 2026

Construction and business inventory costs increased again in the third quarter of 2026, with business inventory recording the strongest quarterly growth.

Highlights:

- The **Troostwijk Index** reached **140.8 points for business buildings and offices, 138.1 points for residential construction and 139.6 points for business inventory**, maintaining the upward trend across all categories.
- **Business inventory costs** recorded the strongest growth, increasing **5.9% year-on-year**, compared to **+4.1%** for business buildings and offices, and **+4.4%** for residential construction.
- **Construction costs** remain above the average of recent years due to persistent wage pressure, a tight labour market and higher rates charged by contractors.
- **Building material** prices generally moved upwards during the quarter, with particularly strong increases in bitumen, sand and plastic products.
- **Production costs** for business inventory accelerated due to the combined impact of collective labour agreement wage increases, labour market constraints, higher component costs and rising commodity prices.
- **Commodity market volatility, geopolitical tensions and international trade developments** continued to create uncertainty around energy, raw material and supply chain costs.

Troostwijk Internaitional Cost Index 2026 

Troostwijk by Accumin analyses global trends in construction costs and machinery production costs as a decision supporting tool for the insurance and real estate sectors. 

**2018-2025 evolution**: pandemic, labour shortages and geopolitical conflicts triggered a profound structural shift in the insurance and valuation sector. 
- A significant cost crisis emerged in 2021, following a period of moderate inflation. 
- As a result, the declared and insured valuations of assets quickly became outdated. 
- Cost developments were not homogeneous, increasing complexity of risk management. 

In **2025**: cost divergences were particularly pronounced, reflecting the uneven impact of inflation, energy prices, wages and global supply chains. 
- Both construction costs and machinery production costs increased by 4,1% globally, while maintaining a high degree of regional dispersion. 
- Marked differences in the case of construction, where increases ranged from the minimum of 2,7% in Australia and New Zealand to a peak of 9,2% in Africa. 
- In machinery production, growth was moderate in Europe with 1,8% and significantly higher in Africa with 9,8%. 



| **Costs** | **Africa** | **Asia** | **A & NZ** | **Europe** | **Latam** | **EEUU & Canada** |
| --- | --- | --- | --- | --- | --- | --- |
| Machinery Production | 185.2 | 148.3 | 129.9 | 128.8 | 139.7 | 136.9 |
| Construction | 194.8 | 148.8 | 144.9 | 147.2 | 147.8 | 148.2 |

**Outlook for 2026**: data is suggesting a slowdown after the exceptional price growth experienced in recent years. 
- Persistent geopolitical risks, currently linked to the conflict in the Middle East, continue to pose potential impacts on inflation and price dynamics. 
- The economic slowdown already visible in some parts of Europe, could also generate deflationary pressures.

Forecast of average increases: 


| **Costs** | **Africa** | **Asia** | **A & NZ** | **Europe** | **Latam** | **EEUU & Canada** |
| --- | --- | --- | --- | --- | --- | --- |
| Machinery Production | 8% | 4.7% | 2.6% | 1.5% | 2% | 4% |
| Construction | 8.6% | 4.6% | 3.1% | 3.1% | 3.6% | 3.6% |

New-build Housing Report Spain 2026 

**The 2026 New-Build Housing Report for Spain**, conducted by **Tinsa by Accumin Spain**, studies the evolution of new-build residential market. The study highlights the growing imbalance between strong demand and limited supply. 
Total sales in 2025 have been pushed to decade-high levels due to significant population growth since 2021, combined with lower mortgage costs, resilient employment and recovering purchasing power. However, new-build specific transactions remain limited and insufficient to address the accumulated deficit. 


- The strongest **price increase variations of +14,1%**, were recorded in Cantabria and Asturias, while minimal variation of -5,4% was recorded in Extremadura. 
- At the same time, **foreign buyers** account for **10%** of total transactions and 6% of new-build purchases. 
- In 2025, **new-build housing prices** rose by **+10,4%** year-on-year, with average values 43% above second-hand housing. 
- Theoretical **purchase effort ratio** for new housing exceeds **45%** in Balearic Islands, Andalucía, Valencia and Cantabria.

At **Accumin**, through rigorous data analysis, we provide buyers and investors with deep market understanding and actionable insights that enable them to make strategic decisions with greater clarity and confidence.

Housing in Mexico 2026: Contrasts and opportunities

The housing market in Mexico has entered 2026 with signs of transformation. In the metropolitan areas of Monterrey, Guadalajara and Mexico City, the availability of construction projects continues to decrease, what increases pressure on prices. 

Most notable trends include: 

- Supply shortage. The limited launch of new projects drives exploitation of existing land, reducing space of units offered but maintaining affordable prices. 
- Prices growth, with upward tendency, due to the stagnant housing supply. 
- Emerging submarkets. The saturation of traditional areas shift investment towards new zones with development potential. 
- Expansion of Multifamily rent, which provides a professional and centralized model of rent management as a safer alternative to traditional renting. 
- Centrality as a decisive factor, with location and commuting times becoming priorities for consumers. 
- Cautious and selective buyer profile, influenced by economic conditions. 
- Ticket price as a guiding reference, with reductions of space offered to keep prices competitive. 


The study describes a heterogeneous outlook for 2026, highlighting emerging opportunities within a global environment of constrained supply.
