Financing landscape under pressure

The real estate market in 2026 is in a phase of structural adjustment. Refinancing dominates proceedings: 95 percent of market observers identify this as the defining factor for the current year, as a survey by EY shows. Numerous financings from the years of low interest rates are expiring – investors must adjust to significantly changed terms.

For ten-year loans, the market expects an interest rate range of between 3.1 and 3.7 percent in the first half of 2026, as confirmed by industry analyses to "Das Investment" in early 2026. This bandwidth reflects not only market volatility but also the increasing differentiation by lending institutions based on property quality and creditworthiness.

At the same time, the importance of alternative financing sources is growing. Private debt – that is, borrowed capital from non-traditional lenders such as insurance companies, pension funds, or specialized debt funds – is gaining significant relevance in 2026. 91 percent of surveyed market participants confirm this development. Where traditional banks act more restrictively, private capital providers fill the gap, but often at higher costs and with shorter terms.

Residential versus commercial real estate: risk and return compared

The choice between residential and commercial real estate remains one of the fundamental decisions for investors. Residential properties offer structural advantages: they are easier to finance, enjoy comprehensive tenant protection, and are considered more stable during economic downturns. The lower cyclical risk makes them particularly attractive for conservatively oriented portfolios.

Commercial real estate promises higher returns but also brings increased complexity. Demand for office, retail, or logistics space reacts significantly more sensitively to economic fluctuations and regulatory changes. Administrative effort is typically higher, as is the risk of prolonged vacancies. Economic downturns often hit commercial real estate harder than residential properties, as the cyclical nature of this asset class shows.

A look at international markets underscores the importance of realistic return expectations: advertised gross returns of 6 to 7 percent often shrink to 3 to 5 percent net returns after deduction of ancillary costs, maintenance, taxes, and currency fluctuations, as analyses for the European market show. This discrepancy between gross and net returns requires detailed calculation.

ESG as an economic metric

ESG criteria – Environmental, Social, and Governance – have evolved in 2026 from a voluntary supplementary strategy to a hard economic metric. 84 percent of investors expect tangible impacts of ESG requirements on financing terms and return expectations, as a survey on the Swiss real estate market documents.

The financial incentives are concrete: a half percentage point interest rate advantage adds up over a typical financing period of 10 to 15 years to a five-digit amount. Banks and institutional investors increasingly differentiate their terms based on sustainability criteria – those who want to finance energy-retrofitted properties with a low CO₂ footprint receive better interest rates than for existing properties without retrofit prospects.

Substance beats label

Practice shows a remarkable shift in priorities: 93 percent of investors question the added value of formal sustainability labels and instead focus on investments in building substance and measurable CO₂ reductions. Certificates alone guarantee neither lower operating costs nor higher rental income – what matters is actual energy performance.

A concrete example of practical ESG implementation is tenant power: through decentralized electricity generation (usually photovoltaic) CO₂ emissions are reduced (Environmental), tenants are offered cheaper electricity rates (Social), and transparent billing systems strengthen Governance. This model improves both the ESG rating and return prospects, as higher transparency in ancillary costs and lower energy costs increase attractiveness for tenants.

Market outlook for investors

Rising interest rates, higher energy prices, and economic uncertainty characterize the framework conditions for real estate investments even in April 2026. These factors have a direct impact on rents, purchase prices, and financing conditions. Investors must make their calculations significantly more conservative than in the past years of low interest rates.

The shift toward mixed portfolios continues. Rather than monoculture strategies (residential only or commercial only, domestic only or foreign only), investors are increasingly diversifying across asset classes, regions, and currencies. This risk diversification serves not only to hedge against local market slumps but also currency diversification – for investors from the Swiss franc region, euro exposure can present opportunities or risks depending on exchange rate developments.

Professional management is gaining in importance: real estate funds and REITs (Real Estate Investment Trusts) provide access to diversified portfolios under professional management. Experienced real estate specialists make decisions on acquisition, management, and sale to achieve optimal returns – an advantage especially for investors without their own real estate expertise or with limited capital for direct investments.

The current market phase requires careful analysis: those who invest now must calculate financing costs realistically, plan for ESG requirements early, and prioritize the long-term value retention of the property over short-term return promises. The 2026 real estate market no longer rewards courage to enter alone, but the quality of the decision.
