The provided web search results mention general topics like buying property below market value or police investigations in Oslo, but none of the evidence directly corroborates the specific claim that Norwegian police are investigating financial assistance for a couple to purchase an Oslo apartment in 2018 at a price below market value. The evidence is too general to confirm this specific allegation.

The evidence indicates that Okokrim (Norway's economic crime unit) has been involved in investigations concerning high-profile figures, but none of the provided web search results explicitly state that a joint investigation team (JIT) has been established *between* Okokrim and France.

One web search result explicitly states that Fabrice Aidan was serving as 'Special Assistant to the Special Envoy of the Secretary-General' and mentions Terje Rød-Larsen's role, but the evidence does not provide enough independent confirmation to verify the full context of his service dates or role relative to Rød-Larsen's specific title/dates.

The evidence confirms Mona Juul's roles (section chief, ambassador to UK) and the general existence of ties to Epstein brought to light by media/documents. However, the evidence does not independently confirm the specific timeline or the nature of the 'couple's ties' during the 2010s period mentioned in the claim.

The web search results confirm that Jeffrey Epstein died in 2019 while in jail awaiting trial for sex trafficking. However, none of the provided evidence sources mention the specific detail regarding him leaving $10 million in his will to the couple's two children.

This claim aggregates multiple specific allegations (Oslo apartment 2018, Epstein trip 2011, home-care services) that are not independently corroborated across the provided evidence set. The evidence is too fragmented to confirm this comprehensive statement.
