An appraisal without complete documents: is that even possible?

Many owners hesitate to enquire because plans, living-area calculations or older documents are missing. In practice this is not an unusual exception, but rather the rule.

Missing floor plans, living-area figures or building documents are no reason to postpone an enquiry. Complete documents are helpful for a market value appraisal, but they are not always fully available at the outset. In an initial consultation, it can usually be clarified quickly which documents are already available, what still needs to be procured, and which information can be supplemented during the course of the work. Particularly with older properties, inheritance cases or long-held properties, an incomplete set of documents is nothing unusual.

It is also important to note: many documents can still be requested from authorities at a later stage. The building records in particular often yields value-relevant information, for example on permits, plans, areas, conversions or structural particularities. Not everything therefore has to be fully available at the outset. Often a missing set of documents can be sensibly supplemented during the course of the work.

What is decisive is not perfection at the start, but a realistic assessment of the case. Missing information can increase the effort and, in individual cases, also affect the processing time. However, it does not automatically mean that an appraisal is impossible. What matters is a careful examination of which details can be reliably substantiated and where further clarification is needed. This is precisely where we support our clients from the very beginning.
