First-Time Buyer New Build Mortgage

What should I consider when choosing a new build mortgage advisor?

Adam: The main consideration is who the advisor works for. Is this part of a service provided by the developer? It might seem like perfect sense to use someone that’s linked to the developer, but that’s not necessarily the case.

When you work with an independent broker like ourselves, we also educate you on the home buying process and new build process specifically. We can help you negotiate on a property.

It’s also important to understand the scope of lenders the advisor has access to. Do they have whole-of-market access? Do they have a limited panel? Do they have any exclusive products specific to new build?

Are there any special considerations or terms and conditions for a first-time buyer mortgage on a new build? What are the benefits and drawbacks of new build homes?

Jon: One of the main considerations is timeframes. Most developers want a quick exchange of contracts, and normally put a deadline in play. If you don’t exchange in time, you could lose your reservation fee.

Also, once you exchange contracts, you are legally bound to buy the property. You would have contributed your deposit for the purchase. After that point, if you withdraw you’ll lose your deposit, even if completion has taken a while, or you lose your job or become ill.

Most mortgage offers have a valid period, normally of six months, although some lenders offer longer for new builds. They can also be extended. It’s important to see from the outset when completion is likely to be, because that could affect which lender we go to.

How long does the mortgage application process typically take for a new build property? Any difference for a first-time buyer?

Adam: There’s no difference in timeframes, whether you’re buying a new build or not. Most lenders tend to publish their average processing times on their website, and this could be a key consideration depending on exchange requirements.

Generally speaking, most lenders have a two-week turnaround – and in some circumstances, it can be quicker, although it can also take longer. That might be influenced by whether they send someone to do a physical valuation or simply do an ‘off plan’ valuation.

Another key factor that can improve efficiency is being prepared prior to making a mortgage application. We help ensure that all your key documents and information are on file before arranging an Agreement in Principle for you, which puts you in the perfect position to make an offer.

It means you are mortgage-ready – and once your offer has been accepted, we can set up a meeting and finalise your application based on the most suitable lender at the time.

How do I get a mortgage on a new build property as a first-time buyer? What’s the process?

Jon: The documents are fairly standard with any mortgage application. It’s all the different proofs: income, commitments, deposit. We offer a free initial consultation where we look at your borrowing capacity and potential lender options, and go through the costs.

We like clients to go through this before they start viewing properties – then they can be confident that they’re able to make an offer. A developer wants to sell its new builds as quickly as possible – so they want to know you’re in a strong position. We can obviously get you there.

How can a mortgage broker help here? Have you got anything to add?

Adam: Aside from the mortgage application, a key benefit of using our service is our knowledge and expertise on the housing market. We like to help educate our clients on property and, specifically, the new build developments they’re looking at.

We explore how and when to negotiate with a developer, and what they can typically offer you. At the moment in October 2025, a lot of developers are actively offering incentives such as a deposit contribution.

But with a contribution towards the deposit, what else are you getting with the property? Have they cut back on other expenses – such as the quality of your kitchen or bathroom?
Will they include flooring? Are they completing the garden for you? That can be a big expense these days.

It’s also important to understand that with a new build, you’re paying a premium. It’s like buying a brand new car. Consider how long you genuinely see yourself living in that property, because if you’re just buying for a couple of years, you do risk losing money.

Jon: Also, your mortgage is assessed on your current credit commitments, and obviously people want to buy things for the new property. Just bear in mind that a lender may do further checks before they release funds.

If you’re taking out any credit to furnish the property, that could have an adverse effect on your mortgage. The lender might refuse to release the full funds, and you would need to cover any shortfall. That’s quite key – it could be nine months down the line by the time the mortgage goes through.
