I haven't been covering the stock intensely WebbJ but I believe an element of disruption relates to property management. The traditional model is to either hire a property manager to cover bond, rent, maintenance and admin/legals for your property at a commission of the rent, between an estimated 5% and 10%. The alternative was to educate yourself on the obligations and operation of being a landlord from multiple agencies (Dpt. Fair Trade, Bond Board, a portion of a service from a Prop Mngr etc) and run a certain calculated risk in managing your property yourself to save on costs. The risk being that you may not be a real estate legal expert dealing in real estate legalities.
Rent.com.au offers a space where as a landlord all the resources to self-manage your property are packaged for easier implementation which IMO reduces the legal risks and the daunting nature (for some) of being a self managing landlord. Add this to the advertising segment of self managing and I see a large portion of market share taken out of the hands of property managers and put in the hands of the now empowered self-managed landlord. This is where I see the disruption, regardless of the scale.
