Questione giuridica chiave
Whether the foreign property had been valued too high for supplementary benefits purposes under Art. 17(4) ELV
Decisione estratta
The record did not permit a sufficiently reliable determination of the property's market value; further inquiries were required, and the case had to be remitted for a new calculation.
Motivazione estratta
The earlier Swiss-franc cost and prior valuation were based on the wrong parcel and were not enough; the private expert report raised serious doubts and comparable-object valuation was necessary. If such a valuation cannot be obtained with reasonable effort, the 2006 expert report may be used.
