## Self-build mortgage for a barn conversion

A self-build mortgage for a barn conversion funds the purchase of an unconverted barn and the cost of converting it into a home. Self-build barn conversion mortgages usually release money in stages, either in arrears (after each stage of work is valued) or in advance (before each stage, to help cash flow). Typical stages run from purchase and initial works through to wind-and-watertight, first fix, second fix and completion.

Lenders will want to see planning consent, costed plans and evidence that the project is fundable to completion. Once the conversion is finished and signed off, many borrowers re-mortgage onto a standard residential product, so structuring the project with that exit in mind, keeping full records, certificates and warranties, makes the eventual re-mortgage smoother.
