Airbnb gimmick aside, RNT are on the right track with their rent-specific features/integrations that give them a point of difference from the big players including:
RentBond - integration with FXL to pay bond over time instead of upfront.
RentCheck - Tenant background/reference check
RentConnect - helping renters set up utilities etc
RentReports - suburb/ rental data

They need to continue to build innovative, rental-specific functionality/integrations (without bs gimmicks) that give them points of difference and make it an easier/better choice (or at least a part of their process) for renters, landlords and agents to use their site. Once traffic gets high enough it will become a no-brainer to use the site for rental listings as it currently is for the big players (REA etc) due to exposure.

They have capital for some more innovation and marketing to get the business to the next level and I for one am glad they have a new CEO with good experience in IT, hopefully he's the man to take this business to the next level.
