Guide to Self Build Mortgages

A self-build mortgage is a loan which is taken out to fund a property build you are completing yourself.

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

Traditional mortgages are not suitable for self-builders. During a self-build, funding is required at different stages of the build to finance the project as it moves forward compared to one lump sum.

It is important to understand how self-build projects work from a financial viewpoint.

When are funds released with a self-build mortgage?

Funding is released in stages as the build progresses. 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. This will depend on the lender, although most lenders will offer only arrears stage payments.

Preparing a cash flow budget will help prepare you from the very beginning of the project, ensuring you have sufficient funding at each stage. If you need to buy extra materials during a point of the build, you may need to make overdraft arrangements or use savings to ensure you do not run out of funds.

For Arrears Stage Payments, the funds are released after each stage of the build and these payments are not guaranteed.

For Advance Stage Payments, the funds are released before each stage of the build and are guaranteed.

How much money can be borrowed with a self-build mortgage?

The amount you can borrow will ultimately depend on your individual financial circumstances, including incomings and outgoings, and any outstanding debt. A deposit of 20% is generally required for the land, and funds for the first phase of build.

Lenders will all have their own maximum loan amount, with some lenders applying their own limits on borrowing for buying land, build costs, and gross development value. A mortgage will not be offered if it is not deemed unaffordable.

All mortgage loans are on an interest-only basis to keep payments minimal throughout the build and help aid cash flow.

There will be certain paperwork which your lender could request when applying for a self-build mortgage.

This could include:

• Copy of planning permission
• Copy of a detailed plan of the build including drawings and specifications
• Copy of building regulation approval
• Proof of site insurance and new build warranty or Professional Consultant Certificate
• If required, architect’s professional indemnity cover

As well as an initial valuation, the insurer or architect will visit the site throughout the build to ensure it has been built to the correct standards.

1. Determine your budget: This will depend on your income, expenses, the costs of the land and building materials.
2. Find your plot of land: Once you have determined your budget, you will need to locate a suitable plot of land with permission to build on.
3. Develop a detailed plan: The plan should include the design, cost of materials, and timeline for the project. The mortgage lender will need to see this too to approve your loan.
4. Documentation: Additional documentation will be required compared to a standard residential mortgage, including insurances, and planning permission.
5. Apply for a self-build mortgage: Your mortgage broker will help source a lender which meets your lending objectives and suitable for your circumstances. Once the lender is secured, your broker will start the application process.
6. Get the mortgage approved: The lender will need to carry out a valuation of the plot and the proposed build to determine the amount they are willing to lend to you. When they are satisfied with the valuation and your application, they will issue the mortgage offer.
7. Hire a solicitor: The solicitor will handle all of the legal aspects of the self-build project, including the purchase of the plot and the building contract.
8. Planning permission and Building regulations: Before you begin the build ensure the necessary planning permission, pre commencement conditions are satisfied, and building regulations are in place.
9. Monitor the building work: With the mortgage offer, you can start the build whilst monitoring the project carefully.
10. Draw down the mortgage: At each stage of the build, you can draw down the mortgage, as agreed with the lender.

At the end of the build, or 24 months after the funds were first released, your mortgage will revert back to a repayment basis for the rest of the term. You may decide at this point to remortgage to another lender or with your existing terms.
