    Self Build Mortgages

    What is a Self Build Mortgage?

    A self-build mortgage is a type of loan which is taken out to fund a property build you are completing yourself, rather than purchasing a property that has already been built.

    Funding is provided at various stages of the construction process, allowing the borrower to gradually draw down the funds as the project progresses.

    • Self building a new property
    • Custom building
    • Barn conversions
    • Renovation projects

    Why a traditional mortgage won’t work

    Self build mortgages differ in a number of ways to a standard residential mortgage, largely in the way they are funded.

    With a traditional mortgage, the money that is being borrowed is released on the day of completion as one lump sum. This is not suitable for self builders as funding is required at different stages of the build to finance the project as it moves forward.

    What are Arrear and Advance Stage Payments?

    There are two types of stage payments available: arrears and advance payments. This determines whether the mortgage payments are made to you either before or after a certain stage is completed.

    Typically, stage payments will be released in arrears of work being complete. A valuer shall be instructed prior to each stage being released to ensure progress is being made and the end value is still on target.

    For Arrears Stage Payments, the funds are released after each stage of the build and these payments are not guaranteed. This is a suitable option if you have savings or access to alternative funding.

    For Advance Stage Payments, the funds are released before each stage of the build and are guaranteed. This can help ensure your funds are secured, purchase material beforehand and reduce the risk of running into cash flow issues.


    Please remember your home may be repossessed if you do not keep up repayments on your mortgage.
