Our city's auction rooms are busy with multiple bidders on quality properties.
Outside the auction rooms, homes are receiving multiple offers.
"As we said in March, it's a seller's market at the moment and we predict this buoyancy will continue for some time," says Mr O'Rourke.
He says sales in the upper end of Hamilton's market were particularly strong.
"While there is confidence in both ends of Hamilton's residential housing market, homes above $1 million are selling strong and represented 3.3 per cent of city house sales during the first four months of the year.
That compares to just 1.6 per cent of market sales in the first four months of 2017.
"Lifestyle properties on the edges of the city are now pushing through the $2 million dollar barrier.
Even six months ago, we used to see resistance from buyers to purchase properties above $1.8m.
This resistance has certainly eased and is another factor that's pushing Hamilton's median to record levels," he says.
Total value of homes sales in Hamilton city was $144,225,550 during April. The median listing price was $544,000 while the median sale price was $562,000.
