What Is a New Build Mortgage?
A new build mortgage is simply a mortgage used to buy a newly built home, usually from a developer.
Although the mortgage itself works in a similar way to any other residential mortgage, buying a new build property often comes with additional considerations. Lenders may apply different criteria to new build homes, particularly when it comes to:
- deposit requirements
- property type
- incentives offered by the developer
- affordability assessments
- timescales between reservation, exchange and completion
This means it can be helpful to speak to a mortgage adviser who understands the new build process and can explain how it may differ from a standard purchase.
Why Buying a New Build Home Can Be Different
Buying a new build home is often different from buying an older property.
With a standard purchase, the property is already built and ready to move into. With a new build, you may be dealing with a developer’s reservation process, stricter deadlines and, in some cases, a gap between exchanging contracts and the property being finished.
A new build purchase can involve:
- tighter timescales set by the developer
- mortgage offers needing to remain valid until completion
- lender restrictions on certain types of new build homes
- extra attention on incentives or discounts offered by the builder
- different deposit requirements depending on the property and lender
These factors do not mean buying a new build is a bad idea. They simply mean it is worth getting clear advice early so you understand the process and avoid unnecessary surprises.
How Much Deposit Do You Need for a New Build?
The amount of deposit you need for a new build mortgage will depend on your circumstances, the property you are buying and the lender’s criteria.
Some lenders may take a different view of new build properties compared with older homes, especially where flats are concerned. Deposit requirements can vary, and some lenders may be more flexible than others.
Your deposit could come from:
- your own savings
- a gifted deposit from family
- equity from a property sale
- support through an eligible scheme, where applicable
If you are buying a new build property, it is important to understand how the lender views your deposit and whether any developer incentive may affect the way the purchase is assessed.
At Your Mortgage Expert, we can help you understand what may be possible based on your own circumstances.
Developer Incentives and New Build Mortgages
Many developers offer incentives to attract buyers. These can include things such as:
- deposit contributions
- payment of stamp duty or legal fees
- upgrades to fixtures and fittings
- cashback
- part exchange support
These incentives can be helpful, but they can also affect how a lender views the purchase. Not all lenders treat incentives in the same way, so it is important that they are disclosed properly and considered as part of the mortgage application.
This is one of the reasons why specialist new build mortgage advice can be valuable. We can help you understand how incentives may affect the mortgage process and which lenders may be more suitable for your circumstances.
New Build Mortgage Timelines and Expiring Offers
One of the biggest challenges with new build purchases can be timing.
You may reserve a property before it is finished, which means there can sometimes be a gap between securing your mortgage offer and the property being ready to complete. If the build is delayed, this can create concerns about whether the mortgage offer will still be valid when the time comes.
This is why planning matters.
When arranging a new build mortgage, it is important to think about:
- when to apply
- how long the mortgage offer may last
- whether an extension might be needed if completion is delayed
- how developer deadlines fit with the mortgage process
We can help you understand the timing of a new build purchase and guide you through the process as clearly as possible.
Schemes That May Help You Buy a New Build Home
Depending on your circumstances, there may be schemes or buying routes that can help you purchase a new build home.
These may include:
Shared Ownership
If Shared Ownership is available on the property, you buy a share of the home and pay rent on the part you do not own. This can sometimes reduce the deposit and mortgage needed compared with buying outright.
First Homes and other regional or developer led opportunities
Availability varies, but in some cases buyers may be able to access support or discounted purchase arrangements depending on eligibility and location.
Family support
Some buyers use gifted deposits or wider family support to help make a new build purchase possible.
Because schemes and lender criteria can vary, it is important to understand which route may suit your circumstances best and how it fits with the mortgage process.
