Self Build Mortgage

Building your own home is a major milestone, and the right mortgage guidance can make the process far smoother. At MortgageLine, we specialise in self build mortgages and work with leading lenders to secure staged drawdown funding that follows your build from foundation to finish. Our expert brokers offer clear, practical support at every step, helping you understand your options and manage costs with confidence throughout your project.

Self build mortgages release funds in stages as your home takes shape, from groundwork to final finishes. This means you only pay interest on the amount drawn down at each step, giving you more control over cash flow and helping you manage your budget throughout the project.

Because lenders assess the completed value of your home, you may be able to borrow based on your plans rather than the current site value. This can offer greater flexibility, especially if you’re building on family land or designing a home that will significantly increase in value once completed.

Mortgage Affordability

Borrowing & Deposit

Self build mortgages typically allow you to borrow up to 90% of the site value and construction costs, so you’ll need at least a 10% deposit from savings or a family gift. It’s also important to budget for additional build-related expenses.

Key points:

  • Borrow up to 90% loan-to-cost
  • Minimum 10% deposit required
  • Architect, solicitor, and planning fees apply
  • Stamp duty and moving costs should be planned for

Income & Affordability

To approve your application, lenders need to see clear evidence you can meet future repayments. This usually includes a record of savings or rent payments, plus proof of steady income through employment or self-employment documents.

What lenders look for:

  • Six-month history of savings or rent payments
  • Three recent payslips (if employed)
  • Two years of tax returns (if self-employed)
  • Strong, consistent repayment capacity

Understanding the tax implications of a self-build project is crucial for accurate budgeting and long-term planning. Several taxes may apply during and after your build, and knowing what you can claim back can significantly reduce your costs.

Help to Buy

First time home buyers will qualify for up to €30,000 as a tax rebate on tax paid over the last 4 years with the Help to Buy Scheme.

Stamp Duty

Stamp duty may apply when purchasing land or property. In some cases there may be exemptions when buying residential property. Always check current rates and eligibility before progressing with your site purchase.

VAT (Value Added Tax)

VAT applies to most construction materials and services. However, self-builders may reclaim VAT on certain qualifying expenses once the property is completed. Understanding the reclaim process can help maximise savings and keep your build on budget.

Capital Gains Tax (CGT)

If you sell your self-built home in the future, CGT may apply on any profit. Reliefs are available — especially if the property was your principal residence — so professional tax advice is recommended before making long-term decisions.

Local Property Tax (LPT)

All homeowners in Ireland must pay Local Property Tax annually. The tax is based on the market value of your completed home. Factoring this into your ongoing costs helps you plan your long-term budget effectively.

Self-build projects in Ireland must meet specific planning, construction, and energy standards. These regulations ensure your home is safe, compliant, and built to modern performance requirements.

Planning Permission

You must obtain planning permission from your local authority before starting your build. This involves submitting detailed designs and ensuring the project meets local development guidelines and zoning rules.

Building Regulations

Your build must comply with Irish building regulations covering structural integrity, fire safety, insulation, ventilation, accessibility, and overall quality. These standards ensure your home is safe, durable, and energy efficient.

Building Control Regulations

Self-builders must appoint a competent builder, architect, or engineer to act as an assigned certifier. They oversee construction, ensure compliance throughout the build, and issue certification once completed.

Energy Performance Requirements

New homes in Ireland must meet strict energy performance standards, including insulation levels, air-tightness, and renewable energy contributions. These requirements help reduce energy costs and support sustainable building practices.

Michael from Mortgage Line has been a God sent! I thought I would never get a mortgage but he made it seem so simple! Even though I kept throwing him curve balls, he never seemed to worry, nothing seemed like an issue. Before meeting Michael I never thought I'd have the need for a broker. Now I'm telling all my friends to get down to Mortgage Line!

We couldn’t recommend Michael Ivory highly enough! It took us quite a while to find the right property, but Michael was incredibly patient and supportive throughout the whole journey. He guided us step-by-step and seamlessly handled a couple of application renewals to keep our approval extended for another 12 months. Having his expertise and support made the process so much easier for us.

Our clients frequently ask us various questions. Some of them are listed below:

A general rule of thumb is that you can borrow up to 4 times your gross annual income within the Central bank rules. The max mortgage amount will also take into account the overall cost of construction and the completed property value. MortgageLine will help you get your head around what is possible.

When self building a home you do not need all the money up front. You can draw down the mortgage in stage payments as the work is done. This means you only borrow what you need when you need it and this keeps the monthly payments lower while the property is under construction.

When you build a new home, you will also need cash to fund additional costs such as the following:

Mortgage protection (life cover) and home insurance – we can arrange this for you and your mortgage adviser will be happy to help and provide advice on costs.

Valuation fee – The mortgage lender will require a local valuer to value your new home. The mortgage valuer will initially estimate the finished property value and then they will also visit the property when it is fully complete. Mortgage valuations fees are approx €150.

Solicitor Fees – your solicitor will register the property and manage the drawdown of funds from the mortgage lender. MortgageLine will be on hand to help too.

Architect / Engineer fees – you will no doubt need an Architect to draw up the plans and seek planning permission.

Stamp duty – Log on to revenue.ie for the latest stamp duty rates for self builds.

Moving in costs – you will need a budget for decorating and furnishing your new property

To qualify for a self-build mortgage in Ireland, applicants must meet the following criteria:

  • Applicants must be at least 18 years old to be eligible to apply for a self-build mortgage.
  • The maximum repayment term for a self-build mortgage is up to 35 years. The exact term offered will depend on the applicant’s age at the time of application and their financial circumstances.
  • The mortgage must be secured on the property being built. This means that your property will serve as collateral for the mortgage. The mortgage agreement will be secured either by a mortgage or a right related to residential immovable property.
  • Life insurance and home insurance are mandatory. Life insurance ensures that the mortgage can be repaid in case of the borrower’s death, while home insurance protects the property against damage or loss.

By meeting these criteria, applicants can pursue financing for their self-build projects, ensuring they have the necessary support to complete their new home construction in Ireland.

You begin making repayments as soon as you draw down funds, but only on the portion drawn. Because funds are released in stages, your repayments start low and increase as the build progresses until the full loan is drawn.

Yes. Lenders require an architect or engineer to provide drawings, costings, compliance certificates, and stage completion reports. They also need professional indemnity insurance to certify that each stage of the build meets regulatory standards.

If you’re planning to build your own home, MortgageLine is here to make the process smoother, clearer, and far less stressful. From comparing lenders to managing your staged drawdowns, our expert advisers guide you through every step, helping you secure the right self build mortgage and bring your new home to life with confidence.
