There are plenty of resources online to find homes that are scheduled for foreclosure.
The MLS has information on foreclosure or short sale properties that have been "listed".
Foreclosure Radar has information on properties that have received a notice of default( Typically 90 days delinquent )and and or a notice of sale (21 days away from an auction date).
Given the current markets scenario there is a lot of competition and bidding wars for properties that have just been listed for a short sale.
The best way to bid on foreclosure properties today would be to identify the properties that you may want to buy that are in some stage of default and make contact with the homeowner directly prior to the property being listed.
