Pre Foreclosure and Tax Sales

[Account Closed]

Right now I have been tracking the foreclosure filings that have been coming out of the counties newspapers, with plans of skip tracing these individuals. I am wondering though with the foreclosure auctions a month down the road, is their enough time for me to reach out to the owner and try and get the property under contract with the intent of wholesaling it or do I need to focus on another avenue of trying to wholesale pre foreclosures. Besides looking at these newspaper filings what other ways can I go about getting these pre foreclosure filings as early in the process in order to have enough time to pull of the deal. 

My question for the tax delinquent leads is basically the same as well. If I get the properties that are going up for tax sale 30 days before the sale, is there still enough time to pull off the deal?
