"It started at a million and didn't stop until it reached $1.366 [million]."
He was surprised at the final sale price and had expected the property to fetch in the region of $1.2 million.
"It's probably a bit more than what we were expecting."
The vendors, who were involved in the construction industry, were a young family who originally planned to make it their long-term family home. However, they had decided to move to Pakuranga for the area's schools.
Mr Haydon described the family's $366,000 capital gain as "not too bad" for just 17 months' ownership - though they had spent an unknown amount on improvements.
They had "tidied up" the property - which included adding a deck and painting - but much of the renovation work had already been completed by the previous owner.
The 151sq m home, described as having "loads of charm", is in the Ellerslie School zone and "is all ready for you to simply move in and enjoy", the listing ad reads.
It features "light filled living areas overlooking the deck and garden where kids can play outside while you entertain family and friends".
The house also boasts a modern kitchen with a central island bench, four generous bedrooms, and a modern tiled bathroom. Concept plans have also been drawn up for an ensuite.
"With plenty of storage throughout the home plus a large double garage with separate storage room (which may be converted to an office), this family home will exceed all your expectations."
Mr Haydon understood the purchaser planned to develop the property, which was likely to mean pulling down the newly renovated home.
"It's subdividable. [But] it's difficult to leave the current house on-site."
