Residual Useful Life Appraisal: Realistic depreciation instead of flat-rate assumptions
For rented residential properties, tax depreciation (AfA) plays a key role in ongoing profitability. In practice, however, depreciation is often applied very broadly – regardless of the actual condition of the building. In Berlin in particular, where a large proportion of housing stock consists of older and post-war buildings, this flat-rate approach may differ significantly from reality. A residual useful life appraisal makes it possible to align depreciation with the actual economic remaining life of the building, provided certain conditions are met. This article explains the basic principles, puts the topic into context, and highlights what property owners should pay attention to.
What is a residual useful life appraisal? A residual useful life appraisal estimates the remaining economic lifespan of a building. It does not concern market value or sale price, but focuses solely on the question: […]

An energy performance certificate is no longer enough – why your condominium owners’ association now needs an “Individual Renovation Roadmap” (iSFP)
An energy performance certificate – most property owners are familiar with it by now. An Individual Renovation Roadmap (iSFP), by contrast, is still new territory for many. Yet for a property such as a condominium owners’ association (example) in Berlin-Friedrichshain (built in 1905, 20 residential units, gas central heating), it becomes a key strategic tool. It combines clear technical planning, concrete public subsidies and a reliable planning framework through 2026 and beyond.
The energy performance certificate: mandatory, but not a renovation plan An energy performance certificate is legally required when a property is sold or rented. It shows: the energy demand or energy consumption of the building […]

Property Sale in Berlin via GmbH or GbR: Transparency Register Entry is Mandatory
Are you planning to sell a property in Berlin through a GmbH, GbR or eGbR? Then there’s one essential legal requirement you need to know: Without an entry in the Transparency Register, the notary is not allowed to certify the sales contract. This rule applies to both buyers and sellers. Especially in Berlin, where many properties are held by companies or private partnerships, missing registration is one of the most common causes for delays—or failed sales. In this article, we explain what you as a property owner need to know to ensure a legally compliant sale—and why you should take care of this requirement early.
What is the Transparency Register? The Transparency Register is a central database that records the beneficial owners of legal entities and partnerships. A beneficial owner is typically a natural person who holds more than 25% […]
