How do self-build mortgages work?

Can you get a mortgage for self-build projects? And exactly what does a self-build mortgage cover? Undertaking a self-build poses endless questions. As well as the actual planning and building stages, self-builders also need to navigate the process of securing finances for the project. 

Here, we provide a simple guide to self-build mortgages, including how they differ from normal mortgages and what an interested party may have to do to secure one.

Yes - self-build mortgages are specifically designed for individuals who want to build their own home. Funds are released in stages, requiring the borrower to have a higher credit score and down payment, as well as a detailed construction plan and budget.

The process of obtaining a self-build mortgage differs from that of a traditional mortgage in a few key ways.

First, with a self-build mortgage, the lender typically releases funds in stages as the construction of the home progresses. This allows the borrower to access funds they need as they need them, rather than having to borrow the entire amount up front. This also allows the lender to ensure construction is progressing as planned and funds are being used as intended.

Second, self-build mortgages often require the borrower to have a higher credit score and a larger down payment than traditional mortgages. This is because the lender is taking on more risk by lending money for a home that is still being built, and they want to ensure the borrower has the financial means to complete the project.

Finally, self-build mortgages often require the borrower to have a detailed construction plan and budget, as well as a professional builder or contractor overseeing the construction. This is to make sure that the project is feasible and that the lender's funds are being used effectively.

The exact mortgage rate, term, and offer will be based on each individual’s conversations with a lender or mortgage advisor. However, the most common Loan-to-Value (LTV) for self-build mortgages is 80%, meaning you’ll have to put down a 20% deposit on the land and property.

A self-build mortgage typically covers costs associated with the construction of a new property. This includes the land purchase, building materials, labour costs, and other expenses related to the construction process. The exact coverage and terms of a self-build mortgage can vary depending on the lender, but generally, the mortgage will provide funds at different stages of the construction process.

1. Prepare a detailed construction plan and budget. This will include architectural drawings, a detailed list of materials and labour costs, and a timeline for completion.
   
   
2. Find a professional builder or contractor. This person will be responsible for overseeing the construction and will work with the lender to ensure that the project is progressing as planned.

6. Complete the mortgage application process. This will typically involve filling out an application form and providing all necessary documentation.

8. Provide the lender with a detailed construction schedule. This will help the lender to keep track of the project and ensure that funds are being used as intended.
