Setting bid limits at auctions

[Albert Yamoah]

When purchasing homes at foreclosure auction, investors/end users are not able to do due diligance until after purchase. Is there a formula (along with fervent prayer) for setting limits to the amount one will bid on each house (i.e. calculating costs such as rehab when the house cannot be inspected)?

like @Wayne Brooks said, you can do a lot of due diligence prior to auction. If empty use your wholesale buyers key (see pic). If occupied, get a tour from the occupants.
