If you want to create your first home rather than buy an existing one, you’ll likely need a self-build mortgage. But as a more complex project that comes with slightly higher risk for the lender, what would you need to secure such a loan, and can you qualify when you haven’t owned a home before?
This guide explains all you need to know about the self-build mortgage landscape as a first-time buyer, helping you on your way to building your dream home.
Can you get a self-build mortgage as a first-time buyer?
Yes, you can. Your choice of lenders and deals will be narrower than if you were buying an existing home, a new build, or opting to self-build after years of previous home ownership, but it’s still possible.
A broker would be able to share which lender to apply to and how to secure a good deal.

Eligibility criteria
In order to secure a first-time homebuilder loan, you’ll have to meet a series of requirements, just like with any kind of mortgage.
While each lender will have their own criteria, they typically include stipulations around:
Income: A lender needs to know you’ll be able to repay the loan, which means you have to have a reliable income that will adequately cover the repayments. Lenders usually multiply your salary by 4 or 4.5 times to assess how much they think you can afford to borrow.
Age: As with any mortgage application, you’ll need to be older than 18 but some lenders stipulate that with a self-build mortgage the applicant must be over 25.
Credit history: First-time buyers and self-building both equate to a higher risk level in the eyes of a lender. Having bad credit could be an extra risk element they’re not willing to take on, while good credit would reassure them of your ability to repay.
Should you have bad credit, don’t disregard your plan though. Instead talk to a broker about finding a specialist provider and ways of improving your credit.
For a self-build mortgage you’ll also need to have:
Planning permission: The lender will need to know that you have the authorization to build on the land you plan to use and that you have the building regulations approved.
Detailed building plans: These should show exactly what you plan to build and include a timeline, a breakdown of the various costs of labour and materials, a risk assessment and contingency plans.
Contracts: As a first-time buyer, lenders will likely want you to team up with professional home builders to reduce your risk level. Sharing the details of the construction team via a contract will strengthen your application.

Deposit requirements
If you’re a first-time buyer opting for a residential property, it’s possible to get a mortgage with as little as 5% saved as a deposit.
But building a house as a first-time buyer, means the minimum deposit is usually much higher at 25% of the build cost. Sometimes, a lender may require up to 40% as a deposit.

Where to apply
The market is fairly split regarding which lenders offer self-build mortgages. Barclays, TSB, and HSBC, for example, don’t offer such a product, but Together, Vernon Building Society, and Beverley Building Society do.
When it comes to first-time buyers, that selection of lenders reduces yet again, but you’ll find that there is still a selection to apply to, including:
- Halifax Intermediaries
- Scottish Building Society
- Progressive Building Society
- Earl Shilton Building Society
The rates they’ll offer will likely be slightly higher than on other residential mortgages to mitigate the risk. To discuss whether or not you’d meet the criteria and assess whether there are potential deals to be had with specialist lenders that only deal with brokers, talk to an expert.
Alternatives to a self-build mortgage
If a self-build mortgage isn’t a viable option for this project, there are other options that could help.
These include:
The Help to Build initiative: While you’d still need to apply for a self-build mortgage with this option, this government scheme boosts the deposit for applicants. This makes you attractive to more lenders, thus increasing your chances of getting a mortgage. The government loan is repaid at the end of the loan term, while interest is paid over time.
The First Homes scheme: This government scheme allows first-time buyers to purchase a home at a significant discount. New builds are eligible for the scheme, and while you wouldn’t be building the home yourself, you’d still be purchasing a brand-new home. You’d be able to work with the developer to make some modifications so that the style is more in line with what you’re looking for.
Right to Build register: Created by the UK government in 2016, this initiative allows you to register your interest in potentially creating your own home. This information is funnelled to the relevant local authority, which will, in turn, keep you updated should any opportunities that allow for individual permits in plots in your area open up.

Other potential avenues of funding include:
A bridging loan: This is a short-term loan that provides the money you need until you’re able to secure longer-term finance. In this situation, it could be used to cover the construction costs until you can sell the completed property or take out a residential mortgage on it.
Personal finance: If you plan to use the property to live in once it’s complete, you could apply for a personal loan. While common uses tend to be debt consolidation to pay for a wedding or a big holiday, home improvements do fall within their remit.
Commercial finance: If you plan to use the completed property for business – perhaps you want to open a gym or restaurant – you could consider various types of commercial finance such as commercial development finance, mezzanine finance or joint venture property development finance.

FAQs
Yes. If you’d like to take out a mortgage solely to buy a piece of land, there are lenders open to this arrangement. You should however expect higher rates. A broker would be able to help secure one of the most competitive available.
You will need to apply to the local authority who will make an assessment based on what you plan to build and whether there are any restrictions in that area. If you’re working with an architect, they should be able to help with your application.
