How New Build Incentives Affect Your Mortgage

Can you get a mortgage if a builder offers incentives?

Yes, most lenders will accept builder incentives, provided they are disclosed correctly and fall within the lender’s criteria.

The key issue is that lenders want to understand the true value of the property. If incentives are too generous, they may reduce the value they use for mortgage purposes or restrict how much you can borrow against the new build property.

What are builder incentives

Builder incentives are benefits offered by developers to encourage buyers to purchase a new build property.

They are commonly used when developers want to boost sales, meet targets or help buyers overcome affordability challenges.

These incentives can take many forms. Some reduce your upfront costs, while others improve the property itself. Although they can be appealing, lenders do not treat all incentives in the same way.

Common examples of builder incentives include:

• Deposit contributions paid by the developer
• Stamp duty contributions
• Cashback on completion
• Legal fees or valuation fees paid
• Part exchange on your existing property
• Upgrades such as flooring, appliances or landscaping

While these incentives may reduce the amount of cash you need upfront, they can influence how your mortgage is calculated. This is why understanding builder’s incentives mortgages is so important before you commit.

What is a builder’s incentives mortgage?

A builder’s incentives mortgage is not a separate mortgage product.

Instead, it refers to a mortgage application where the purchase includes incentives provided by the developer.

These incentives must be disclosed to the lender and can affect:

• The property’s mortgage valuation
• The loan to value calculation
• The amount you can borrow
• The lender you are eligible to use

The mortgage itself works like any other residential mortgage, but additional checks are usually required.

Why builder incentives matter to mortgage lenders

Mortgage lenders are primarily concerned with risk and property value. When incentives are involved, lenders want to be sure the purchase price reflects the true market value of the home and that the incentives are not artificially inflating that price.

Some incentives are considered acceptable and do not affect the valuation. Others are classed as financial incentives and may reduce the amount the lender is willing to base your mortgage on.

Most lenders allow incentives up to a certain percentage of the purchase price. In many cases this is around five percent. If the total incentives exceed that level, the excess is usually deducted from the property value for mortgage purposes.

This means your mortgage may be calculated on a lower figure than the agreed purchase price, which can affect your loan to value and deposit requirements.

Why are lenders more cautious with new build properties?

Lenders often apply stricter criteria to new build homes because they can carry additional risks.

These include:

• Limited comparable sales evidence
• Potential for prices to fall after completion
• Incentives masking the true purchase price
• Delays between exchange and completion

Because of this, lenders usually review incentives very carefully and require full disclosure before issuing a mortgage offer.

How builder incentives affect your mortgage amount

To understand how a builder’s incentives mortgage works in practice, it helps to look at how lenders calculate borrowing.

If you are buying a new build property with incentives within acceptable limits, your mortgage is usually based on the full purchase price. However, if incentives exceed the lender’s threshold, the valuation is adjusted.

For example, if the purchase price is agreed at a certain level but incentives go beyond what the lender allows, the lender may reduce the value they use for lending. Your mortgage is then based on this lower figure rather than the headline price.

This can mean:

• You may need a larger deposit than expected
• Your loan to value may increase
• Your choice of lenders or rates may reduce

Many lenders follow UK Finance guidance when assessing incentives on new build properties.

As a general rule, incentives above 5% of the purchase price receive greater scrutiny and may affect the mortgage valuation.

This does not automatically mean the application will be declined, but it can reduce borrowing or limit lender choice.

Acceptable and non-acceptable incentives

Not all incentives are treated the same by lenders. Understanding the difference helps avoid problems later.

Incentives that are usually acceptable include:

• Developer deposit contributions within limits
• Stamp duty contributions
• Cashback paid on completion within limits
• Legal or valuation fees paid
• Part exchange at market value
• Upgrades that form part of the property such as kitchens or flooring

Incentives that can cause issues include:

• Large cashbacks exceeding lender limits
• Inflated purchase prices to disguise incentives
• Vendor funded deposits with no buyer contribution

Most lenders also expect you to contribute a minimum amount of your own funds. Even if the developer is helping, you are usually required to put in a percentage from your own savings or a family gift.

Disclosure of incentives

One of the most important parts of a builder’s incentives mortgage is disclosure. All incentives must be declared to both the lender and your solicitor.

Developers are required to complete a disclosure of incentives form which details every benefit included in the purchase.

Lenders use this information to assess the true value of the property and confirm how much they are prepared to lend.

Failure to disclose incentives early can lead to:

• Mortgage offer delays
• Re valuation of the property
• Reduced mortgage offers
• In some cases declined applications

What is a Disclosure of Incentives Form?

A Disclosure of Incentives Form is a document completed by the developer detailing every incentive included in the purchase.

This form is provided to:

• The mortgage lender
• The surveyor
• Your solicitor

Its purpose is to ensure all parties understand the true financial arrangement behind the purchase.

Without this form, lenders may delay valuation inspections or postpone issuing a mortgage offer.

Builder incentives and your deposit

Builder incentives can help with costs, but they do not always replace the need for your own deposit.

Many lenders require you to contribute a minimum percentage from your own funds regardless of incentives.

This means that even if the developer offers a deposit contribution, you may still need to provide part of the deposit yourself.

Are builder incentives helpful for first-time buyers?

Builder incentives are particularly popular with first-time buyers because they can reduce the amount of cash needed upfront.

Examples include:

• Deposit contributions
• Stamp duty contributions
• Paid legal fees
• Flooring and appliance packages

While these incentives can make purchasing easier, they should always be assessed alongside the mortgage to ensure the transaction remains affordable.

Benefits of builder incentives when used correctly

Builder incentives can be extremely helpful. They can reduce upfront costs, improve affordability and make a new build purchase achievable sooner than expected.

Benefits can include:

• Lower cash required at completion
• Help with stamp duty and legal fees
• Improved property specification through upgrades
• Smoother transactions through part exchange

The key is ensuring the incentives align with lender criteria. This is where professional mortgage advice makes a significant difference.

Why new build mortgages need specialist advice

New build purchases are already more complex than buying an existing property. Add builder incentives into the mix and the process becomes even more technical.

New Build Mortgage Offers often need longer validity periods. Build completion dates can change. Lender criteria around incentives can vary significantly.

It is easy to choose a lender who appears suitable but later reduces borrowing or delays completion due to incentives.

Can builder incentives affect mortgage offer expiry dates?

Sometimes.

New build properties can take months to complete, particularly if construction is still underway.

This means buyers may need mortgage offers with longer validity periods or offer extensions.

Choosing the wrong lender can result in a mortgage offer expiring before completion, creating unnecessary stress and delays.

This is another reason why obtaining advice early can be valuable.

Getting started with a builder’s incentives mortgage

If you are considering a new build purchase and have been offered incentives, the best time to seek advice is before you reserve the property.

Understanding how incentives affect your mortgage early allows you to negotiate with confidence and avoid costly mistakes.

A conversation with a suitable broker helps you assess affordability, review incentives and choose the right lender from the outset.
