I own an apartment and there's not that many costs. I think rates are like $800 a year and the body corp fees are about $900 a quarter
Mortgage (currently) is only about $900 a fortnight. Works out similar to rent overall, except eventually I get to own it.
Renting is a scam and there should be better protections in place. I only managed to buy my apartment because I lived in a vehicle for 4 years while working full time, and the government shared equity scheme owns 25% of it.
