New Build Mortgages Explained: Deposits, LTV Caps & Incentives

Purchasing a new build is different from purchasing an older home. A mortgage for new build homes often follows stricter rules. Lenders apply specific criteria to new build loans, especially at higher LTV levels. This can mean larger new build deposits and tighter lending limits. 

Lenders often see new build as higher risk. Values can reduce after completion, especially with high borrowing. Because of this, a mortgage for new build properties may require more careful structuring. Speaking to a new build mortgage broker early can prevent issues. 

New build incentives can also affect your mortgage being approved. Deposit contributions, cashback or upgrades may affect lender calculations. Understanding how new build incentives impact valuation is essential before reserving. 

At Stuart Brown Mortgage Services, we specialise in new build loans. As a trusted new build mortgage broker, we guide clients from reservation to completion. 

How Much Deposit Do You Need for a New Build?

New build deposits are commonly higher than standard purchases. Many lenders require at least 10%, but some request 15% or more. Flats can also face lower LTV caps than houses. By paying a larger new build deposit, you are accessing more lender options. 

Many lenders don’t offer 95% mortgages for new build purchases. Some restrict high LTV new build loans because of valuation risks. This is another reason why new build deposits are so important. 

A specialist new build mortgage broker can assess your deposit position early. This ensures your mortgage application for a new build application aligns with lender criteria ahead of reserving. 

How Can Developer Incentives Impact Your Application?

Developers often offer incentives to push people to buy new builds. These can include deposit contributions, stamp duty payments, cashback and free upgrades. While attractive, new build incentives can affect lender calculations. 

Commonly, lenders cap acceptable new build incentives at a percentage of the purchase price. If your incentives exceed that, your mortgage for a new build loan amount may reduce. This can impact affordability and approval. 

At Stuart Brown Mortgage Services we will always review incentive structures before submission to ensure that everything is declared accurately. This will help avoid any last minute issues. 

What Happens to Your Mortgage Offer if a New Build Is Delayed?

New build homes often exchange early. When you purchase the house, completion can be months away. This means understanding mortgage timelines is essential to ensuring that you don’t face any issues or delays. 

A mortgage offer typically lasts 6 months. If your new build faces a delay this can lead you to have to apply for an extension or even completely reapply for a mortgage. 

Our advice is to avoid applying too early, monitor new build timelines closely and stay in frequent contact with your broker.
