Buying a house at a foreclosure auction with financing is a different beast and typically would involve a line of credit.

Purchase price: $89,000 Cash invested: $26,000 Sale price: $160,000 I purchased this duplex located in my hometown at the county auction.

I have noticed an influx of auction/foreclosures in some areas along with hurricane/flood damaged properties.

I haven't bid at an auction before so have a few questions. 

I'm thinking about buying some of these distressed property in my area on the auctions that's bidding starting of a $1 , My father who is a contractor is willing to do some slow fixing it up while I continue to build more capital up and get more houses.

You should work the word "fiduciary" in there, too :) And yea, what the hell, let him pick apart the deal and praise him for his perceptiveness when he hits on something obvious you have thought of. 

I learned the county auction process.  

Besides the typical “as is”, no financing contingency (as in the case of this auction), what other contract contingency do you recommend?

Extra monthly payments is great passive income and the down you can get goes to your cash buyer fund.Not that this is what you should be doing without appropriate background knowledge and experience, but it's an example of how barriers in real estate are really just tests of persistence.Reframe your mindset from, "I can't afford to buy an auction property cash" to "How can I buy this property without cash?"
