New Build Mortgages

New Build Mortgages

We can help you get the keys to your shiny new home.

Lender’s criteria can change if the property is brand new. This may affect the maximum they will lend on the property or even any incentives from the builder (e.g. cashback) making the application unacceptable with certain lenders.

Once your situation has been understood, Kerr & Watson will make a recommendation for the most suitable mortgage continuing to work closely with you, the developer and solicitors from application to completion so exchange and completion deadlines can be met.

How We Help with New Build Mortgages

At Kerr & Watson, we help customers arrange mortgages for new build houses and flats. We compare lenders that accept new build properties and help you understand developer requirements, mortgage deadlines and completion dates.

✓ New build houses and flats – Identifying lenders with suitable mortgage products and deposit requirements for newly built properties.

✓ Buying off-plan – Arranging mortgages for properties still under construction, including those with longer completion timescales.

✓ Developer incentives – Comparing lenders that accept builder deposit contributions, cashback and other purchase incentives.

✓ New build purchases and deadlines – Helping customers arrange mortgages within developer reservation and exchange deadlines.

How Do Mortgage Lenders Assess New Build Properties?

Mortgage lenders have different criteria for new build properties, which can significantly affect your borrowing options.

Some lenders require larger deposits for newly built flats than houses, while others have different rules for property valuations, new build warranties and developer incentives. These differences can affect which mortgage products are available and how much you can borrow.

We compare lender criteria and property requirements to identify suitable mortgage options before you proceed with your purchase.

How Much Deposit Do You Need for a New Build Mortgage?

The deposit required for a new build mortgage depends on the lender, property type and your financial circumstances.

Some lenders offer mortgages with deposits as low as 5% for new build houses, while newly built flats may require a larger deposit. Developer contributions and certain home ownership schemes may also help eligible buyers, although lender restrictions apply.

We compare deposit requirements and available mortgage products to help establish your options.

What Happens If Your New Build Property Is Delayed?

New build properties can take several months to complete, and construction delays may mean your mortgage offer expires before the property is ready.

Some lenders offer longer mortgage offer periods or allow extensions, while others may require a new application if the completion date changes. This can affect your mortgage rate, affordability assessment and borrowing options.

We review lender offer validity periods and help manage your mortgage application if the expected completion date changes.

Kerr & Watson have been absolutely outstanding in terms of knowledge, support and promptness. My case is complicated including three transactions at once and I could have not asked for a better service and support. Look nowhere else when seeking mortgage advice!

I can't recommend Kerr & Watson enough. I moved from another provider I had been using for 20+ years due to missing a purchase after multiple delays and errors. Kerr & Watson took me in as a customer and out did any expectations I had. They also taught me more about mortgages than I thought I knew, making the process easy. A great all round service by every member of the team, at every step.

We could not have asked any more in service, action when required, flexibility when circumstances changed and the determination to get the mortgage sorted for us. We were delighted with every aspect of the service and would highly recommend Kerr and Watson, in particular Marie who is a Gem.

I could not recommend Kerr & Watson highly enough. Marie was absolutely amazing and went above and beyond despite our very difficult circumstances. We would not be where we are today with her. If you are looking for a company that truly cares then you will not be disappointed. Thank you again Marie!
