The Block winners, Alice and Caleb Pearson, will use some of the prize money to start paying off the mortgage on their own renovated homes in Auckland.
The couple, both 26, own two properties and have renovated and sold a third, hopping on the property ladder when they were just 23.
Their first home is a rental on Panmure's Coral Cres, which they bought for $320,000 when the valuation was $400,000 in June 2010, Quotable Value records show.
They live in their third home, on Mt Wellington's Camp Rd. They bought the 1930s two-bedroom character bungalow for $479,000 when it had a valuation of $390,000.
