Sarah and Martin Gaskell never planned to renovate and sell, but the couple became so addicted to the process they're doing it again.
It helped that their five-bedroom former "do-up" in Mt Eden fetched $1.9 million in the Bayleys auction rooms this week.
The couple bought 4 Marlborough St 18 months ago for $1.05 million. That's a difference of $850,000.
But Mrs Gaskell said they spent about $500,000 bringing the 1910s villa up to scratch, so their profit was around $350,000.
It was an 80 per cent rise in value, and 59 per cent above the valuation of $1.19 million.
