House sellers nationwide pocketed $326,000 gross profit on average in the past financial year, the largest windfall on record, bolstered by robust increases in values despite higher interest rates, Domain’s Profit and Loss report shows.

The proportion of profitable house sales also ballooned across the country, rising to 96 per cent, the highest level in 16 years, while the share of units selling for a profit jumped to a 13-year high of 90.7 per cent.
