Financing a property purchase in Monaco is highly structured, with local private banks routinely offering mortgages to both resident and non-resident high-net-worth buyers. However, because of the extreme transaction values, banks rarely offer stand-alone, high loan-to-value (LTV) mortgages. Instead, financing is typically conditional on an asset-backed relationship, where the borrower is required to deposit assets (such as cash, bonds, or investment portfolios) with the lending bank as collateral under a pledge agreement (nantissement). This private banking model ensures loans are secure while allowing buyers to maintain liquidity.
