How is the standard value actually calculated? So far, I have read a lot about tables, etc. Why has this never been made into an online calculator? After all, there is one online for [Geäudeversicherungen] as well...
After I recently received the questionnaire, I tried to research the calculation method and miserably failed. Maybe it's because the revaluation only concerns new development areas and only once. For that, the effort for such an online calculator is not worth it.
Well, effort? Strictly speaking, the assessment must also be initiated anew in the case of a modernization or similar. Basically, one should have the right to know on what basis such assessments are made - it costs a lifetime of real money.
