Here's what I do before I bid;

1. Google around for auction properties.
2. Get the Proclamation of Sale. Read terms esp on who pays the outstanding maintenance fees, quit rent, assessment fees etc.
3. Site visit. Estimate for repairs. If owner stays at the property, cancel and go back to step 1. Get a copy of utility bills for checking.
4. Do title search at land office. Can skip this if master title. If got private caveat by individual then go back to step 1.
5. Go for bidding with a set budget (always below bank valuation).
6. Win - sign contract; lose - return to step 1.
