Mortgages to buy a mansion

A mortgage to buy a mansion is a purchase loan secured against a completed high-value home. Lenders will look closely at the property itself as well as the borrower: unique architecture, extensive grounds, annexes or agricultural ties can all affect which lenders are willing to offer terms.

Because loan sizes are typically large, affordability is assessed in detail. Some lenders apply standard income multiples, while private banks may take a broader view of wealth, including investments, business interests and existing property.

Presentation matters. Packaging complex income correctly, for example, retained company profits or irregular bonuses, can materially change the loan size available.
