Servtech Global IPO, page-9

At the moment their main play is real estate sales as most revenue is generated from that vertical. Mostly from WA, QLD and VIC. The other verticals they talk about ie property mgt, conveyancing, mortgage broker seems to still fall under "real estate" banner. Is this too heavily reliance on real estate (if there's a downturn/slow down). Or is the bigger play the business transaction and outsource service? But it all still seems too tied to the "real estate"..
