What matters in Langenbek
Property valuation: preparation for the specific location and property.
Make comparisons sufficiently precise
Core distinguishes mid and end terraces, and private from communal land. Garden orientation and room sequence complement the living-area figure. A house offered on the same street is therefore a reference point rather than a ready-made valuation.
Put improvements in proportion
A new bathroom changes the property differently from a renewed roof or heating system. Records should therefore be organised by building component. Planned work should also be disclosed so pricing does not rely on visual similarity alone.
Resolve unclear area figures before comparison
If several area figures circulate for a Langenbek house, identify their sources first. Distinguish a residential-area calculation, a note on a drawing and a general figure in an earlier advertisement. Check whether ancillary rooms or subsequently altered spaces were treated differently. The valuation then has a traceable basis before calculating a unit price whose apparent precision could otherwise conceal an unresolved starting area.
Assess condition differences without automatic arithmetic
With similarly built terraced houses, individual refurbishment invoices can tempt a simple adjustment. Instead, establish which function improved and what is known about present condition. The price of earlier work is initially evidence of expenditure. Its relevance to the property must be assessed alongside remaining components, execution and available records; mechanically adding invoices cannot represent those differences in a dependable way.
