Barn conversion mortgage
A barn conversion mortgage is a specialist form of property finance used to fund the purchase, conversion, or refinance of agricultural or redundant rural buildings into residential dwellings. These cases sit outside standard residential lending due to planning complexity, construction risk, and valuation methodology, and therefore require lenders with explicit appetite for conversion projects.
Development finance for self build
Development finance for self build is a specialist funding route used where a borrower does not meet residential affordability criteria, or where the intended exit is sale or cash repayment rather than long-term mortgage lending. It is fundamentally different from a self-build mortgage and is underwritten on project viability and exit strategy, not personal income.
Home renovation loan
A home renovation loan is a form of specialist property finance designed to fund significant refurbishment, structural alteration, or modernisation of an existing residential property. These loans sit between standard residential mortgages and full development finance, and lender appetite is driven by scope of works, property condition, and valuation risk.
