What matters in Langenbek
Sell an apartment building: preparation for the specific location and property.
Record apartments and ancillary areas against each agreement
Begin with a schedule of every rented unit, allocating basements, gardens and parking spaces. Where layouts have changed, comparing agreements, area calculations and occupied rooms is especially helpful. Record discrepancies openly. A space previously described as storage should not enter residential-area totals simply because of the way an occupant has furnished or used it.
Check income against payments received
Set agreed rents alongside actual receipts and service-charge advances. Explain arrears or temporary differences so buyers can follow the figures. For vacant or owner-occupied accommodation, keep a prospective rental assumption separate. The operating-income presentation then describes the evidenced property instead of being silently transformed by an assumption that every unit is already fully let.
Make shared facilities visible in the costs
Check whether paths, parking compounds or technical installations are shared with other properties. Allocate recurring payments and known works to those facilities. Detailed descriptions of previous work help where building components connect. Buyers can then identify expenditure affecting the house being sold and parts of a wider installation that lie outside the owner's sole decision-making control.
Arrange investigation for a whole-building sale
Organise access to different apartments and technical areas without promising unrestricted inspection of every tenanted room. A document index identifies missing or unexamined items. Prospective buyers assess the building with its existing agreements and connections. A possible division into individual apartments is an additional scenario whose prerequisites need separate investigation rather than being assumed within the current offering.
