Due Diligence

Due Diligence - Due diligence refers to the careful and systematic examination of a property prior to purchase. The goal is to identify all relevant technical, legal, financial, and tax-related risks before the purchase agreement is notarized.

Process and Areas of Review in Real Estate Due Diligence

A professional real estate due diligence is divided into several sub-areas, each covering specific risks. Technical due diligence involves assessing the building’s structure, building services, energy efficiency, and potential contamination. Experts inspect the roof, facade, piping systems, and the condition of technical equipment. This process also identifies necessary maintenance measures and their estimated costs.

Legal due diligence focuses on ownership structures, encumbrances on the property register, existing lease agreements, public-law permits, and building code requirements. Among other things, it examines easements, rights of way, building encumbrances, and the conformity of the actual use with the issued building permits. Sites suspected of being contaminated and historic preservation requirements also fall within this scope.

Financial due diligence analyzes the property’s earnings performance. For leased properties, rental income, vacancy rates, lease terms, and tenants’ creditworthiness are evaluated. Cash flow projections are prepared, and achievable market rents are compared with actual rents. Tax due diligence examines the tax structure of the acquisition-in particular, real estate transfer tax, depreciation options, and VAT considerations.

For larger transactions, all relevant documents are compiled in a data room (physical or digital). Sellers provide land registry extracts, building plans, energy performance certificates, lease agreements, utility bills, insurance policies, and maintenance logs there. Buyers and their advisors are granted controlled access to systematically review the documents.

Due Diligence Also Beneficial for Private Individuals

Although due diligence is traditionally standard practice in commercial real estate transactions and for institutional investors, private individuals also benefit from a structured purchase review. Especially when purchasing an existing property, it is worthwhile to commission an expert to assess the building’s condition, check the land registry for encumbrances, and review the operating cost statements from recent years before the deed is notarized. The costs of such an assessment are negligible compared to the financial risks that an unchecked purchase can entail-hidden defects, contaminated sites, or unresolved legal issues can quickly result in five-figure follow-up costs.

Red Flags in Due Diligence

Certain findings in the due diligence process should raise particular red flags for the buyer:

• Missing building permits for existing additions, extensions, or changes in use-the buyer assumes the building code risk
• Unresolved contaminated sites on the property (e.g., former gas station, tannery site)-remediation costs can completely erode the return on investment
• Existing rents well below market rates with long lease terms - the expected rental income cannot be achieved
• Insufficient maintenance reserve fund for condominium properties - high special assessments are likely immediately after purchase

Practical Tip for Nuremberg and Franconia

In the Nuremberg metropolitan region, we recommend that buyers conduct a particularly thorough review of older buildings in neighborhoods such as Südstadt, Gostenhof, or St. Johannis, where historic building stock and numerous renovations over the decades complicate the risk assessment. For properties in former industrial areas-such as Gibitzenhof, along the Frankenschnellweg, or on former AEG sites-a contaminated site assessment (information available from the City of Nuremberg’s Environmental Office via the contaminated site registry) should also be part of the due diligence process. We help our clients connect with the right experts, real estate attorneys, and tax advisors in the region so that the purchase decision is based on a solid foundation.

Frequently Asked Questions

How much does real estate due diligence cost?

The costs depend on the scope and type of property. For a simple technical assessment of a single-family home by an expert, the costs range from approximately 500 to 1,500 euros. For commercial properties or multi-family homes, where a comprehensive legal, technical, and economic review is required, the costs can amount to tens of thousands of euros. Anyone hesitant to incur these costs should consider this: A single undetected defect (e.g., mold behind the siding, water damage in the basement, faulty plumbing) can easily result in €10,000-30,000 in repair costs-meaning the due diligence costs will pay for themselves in any case.

How long does real estate due diligence take?

For a private real estate purchase, a concise review can be conducted within one to two weeks. For larger commercial transactions involving an extensive data room and multiple areas of review, four to eight weeks should be planned. We recommend agreeing on the timeframe during the purchase negotiations-ideally through an explicit due diligence clause in the reservation agreement that grants the buyer the right to withdraw from the purchase if material defects are discovered.

What documents should the seller provide?

Key documents include a land registry extract, cadastral map, approved building plans, energy performance certificate, utility bills for the past three years, existing lease agreements, insurance policies, and evidence of any renovations and maintenance performed. For condominiums, these are supplemented by the declaration of division, community rules, budget plan, annual statements, and minutes from the last three owners’ meetings. The buyer should actively request any missing documents and use their absence as a potential bargaining point for a price reduction.

How do due diligence and purchase review differ?

The terms are often used synonymously in German-speaking countries; strictly speaking, “due diligence” refers to the comprehensive review process of American origin, while “purchase review” is the practical term commonly used in Germany for the same process. In terms of content, both concepts cover the same four pillars: legal, technical, economic, and tax reviews. The difference lies more in the level of formality: For large commercial transactions involving international investors, due diligence reports in a standardized format (e.g., Red Flag Report, Long-Form Report) are common; for typical private real estate purchases in Nuremberg, a concise purchase review with a focused appraisal and land registry analysis is sufficient. We help you determine the appropriate scope of review for your project-an excess of formal reviews increases costs without always providing proportionally greater security.
