Question juridique clé
Whether the cantonal court arbitrarily found that the borrowers had provided 10% own funds by counting not only finishing costs but also act/legal fees.
Solution extraite
No arbitrariness was shown: the fee amount was supported by the file and by documents signed for housing subsidies, and the court could rely on them.
Motifs extraits
The amount was not invented by the judges but derived from the borrowers' own subsidy documents; even if cantonal notary fees were lower, that did not make the figure unsustainable.
