Germany Sees 14% of New Mortgage Loans Exceed Property Values, AFS Warns
Rising concern over mortgage loans in Germany after an AFS report found 14% of new mortgages in Q4 2025 exceeded the properties’ market values, signaling elevated borrower risk.
Rapid summary of findings
A recent report from the Committee on Financial Stability (AFS), attached to Germany’s Federal Ministry of Finance, found that in the fourth quarter of 2025 roughly 14 percent of new mortgage loans in Germany had a loan amount higher than the market value of the financed property. This means about one in seven new borrowers took on mortgages that at least equaled—and in many cases exceeded—the asset backing the loan.
Last year overall mortgage lending in Germany rose compared with the prior year, despite high property prices and comparatively elevated interest rates that make mortgage loans in Germany expensive for many buyers. The AFS figures highlight that a significant portion of this lending carries unusually high loan-to-value ratios and greater financial vulnerability for households.
AFS data and how the metric is measured
The Committee on Financial Stability used supervisory and market data to calculate the share of new loans where the principal exceeded assessed market value. These calculations look at the loan principal compared with the market valuation applied at origination, including instances where purchase-related costs were financed on top of the property price.
Measuring loans in relation to assessed property values is a standard metric for gauging borrower leverage and potential losses for lenders. When lending exceeds the collateral’s market value, both borrowers and banks face larger downside exposure if prices fall or personal finances deteriorate.
Why buyers are taking higher risks
Buyers are stretching to buy in a market characterized by persistent price levels and limited supply in many regions. Many households aiming to enter homeownership are accepting higher leverage to secure a property, particularly in competitive urban markets where bidding and quick offers have become common.
At the same time, the landscape of mortgage loans in Germany has been shaped by rising borrowing costs compared with the ultra-low-rate era; some buyers appear willing to accept these costs for fear of missing a purchase opportunity or because they expect incomes or property values to rise. In select cases, buyers have even financed portions of transaction costs and fees, further increasing loan amounts relative to the property’s market value.
Financial stability and borrower vulnerability
Loans that exceed market value amplify the risk of negative equity if house prices correct, leaving borrowers with debts greater than the resale value of their homes. That situation can constrain household mobility, increase default risk during economic stress, and complicate debt restructuring for lenders.
From a systemic perspective, a rising share of high-leverage loans could make the banking sector more sensitive to property-market shocks. The AFS report flags such concentrated risk as a point of concern for macroprudential oversight, since mortgage portfolios are a large and interconnected part of many lenders’ balance sheets.
Context: prices, interest rates and lending trends
The trend comes against a backdrop of still-elevated housing prices in many German regions and comparatively high mortgage rates versus earlier years. Those factors together increase the cumulative cost of purchasing a home and raise the relative importance of down payments and prudent loan-to-value ratios.
Despite cost pressures, mortgage origination expanded year on year, indicating sustained demand. Analysts point to a mix of factors that keep buyers in the market: demographic pressures, urbanization trends, and expectations of long-term property appreciation, all of which are influencing how mortgage loans in Germany are structured.
Regulatory and lender responses under consideration
Regulators and some lenders are already signaling closer scrutiny of origination practices and borrower affordability assessments. Potential responses include stricter loan-to-value limits, more conservative stress testing of borrower repayment capacity, and sharper oversight of lender practices that permit financing of ancillary purchase costs.
Banks may also revisit pricing, amortization schedules and collateral valuation procedures to limit excessive exposure. The AFS findings are likely to feed into supervisory dialogues and could shape policy guidance aimed at preventing buildups of systemic risk in the housing finance market.
The AFS report underscores a clear trade-off facing prospective homeowners: the desire to secure property in a tight market versus the financial risks of high leverage. The scale of loans exceeding market values in late 2025 raises questions for borrowers, lenders and policymakers about the sustainability of current lending patterns and the safeguards needed to protect households and the financial system from a future shock.
