Right? Germany too. I wouldn’t even have thought this could be a problem…
In some countries, like a poster mentioned, they include the “built” size, not the actual liveable size. Sometimes the balconies are included in that, and it is misleading. Two bedrooms in 900sqf liveable is one thing vs 3 bedrooms in 900sqf built area including balconies.
Maybe it’s different for rentals but you’d think the banks would also want accurate data on the properties they’re mortgaging…and cities for tax revenue…so strange!
Until you measure the apartment later and find out that a) it's much smaller and b) it doesn't matter because you rent the apartment as seen, not as advertised.
