Buying a new build home is hard

Lenders have extra restrictions for new build properties – especially for buyers with small deposits.

That’s why we made New Build Boost

On eligible new build properties, you can get a standard 80% mortgage plus a 15% boost to help you buy your home.

The boost is an equity loan that’s frozen for 5 years and interest-free forever.

Frozen for the first 5 years

The boost is an equity loan which is frozen for the first 5 years. That means if you pay back your boost within those 5 years, you’ll only repay exactly what you borrowed.

Keep or pay off your boost

You can start paying off your boost after the first year of your mortgage.

At the 5-year mark, the value of your boost will jump up or down to reflect any change in your property’s value since you bought. Then it’ll continue to go up or down as the property value changes over time.

Capped at 2x and interest-free forever!

No matter how much your property increases in value, you’ll never have to pay interest on your boost or repay more than 2x what you borrowed.

Plus, in that situation, your home would also have doubled in value!
