I talked to a few people and this is what they have said:
# You don't supply toilet paper or any other little things, not even towels or sheets
# Have the place idiot proof, no dainty, fragile furniture etc. Just have walls, windows and maybe some very basic cheap furniture like a table, sofa etc
# Have large shared fridge but buy a bunch of cheap mini fridges from kmart and lease them out if they prefer them.
# Don't have Gas, idiots will leave it on
# Supply a coin washing machine and dryer and a outdoor line if possible
# You make very clear rules (no heaters etc)
# Put up rules/notices around the place in clear laminated.
# You have regular room inspections
# Internet unlimited for 6 or more people otherwise lower the price and let them get their own or get a limited option and setup a login/quota for each person
# Be selective with tenants, go for quiet Asian girls for the best tenants
# Place ads in Gumtree
# Make it nice for them so they want to stay there, (without spending much money) get rid of any trouble makers promptly or the good tenants will move out. Get the odd newspaper, bring some cheap food you pick up from Asian grocer or just do little things to please the tenants and make them happy to have you as landlord.
Anyway I won't be doing this but could consider it in the future if I purchase the right place.
Been there done that. Did it for 6 years, that was before council tighten the law.
Managed 15 students (2 houses).
Would I do it again, properly now. Very good money. Profit around 30k between 2 houses before tax.
Very easy to run. What is annoying is finding the new tenant once their contact expired.
