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.
Mortgage to build a mansion (self-build)
A mortgage to build a mansion is a self-build mortgage that releases funds in stages as construction progresses, rather than as a single advance. Typical stages run from land purchase through foundations, wall plate, wind-and-watertight, first fix and completion, with the lender inspecting or revaluing at each stage.
