Joe and Teresa Giudice -- Wanna Buy Their House for $100?

Teresa and Joe Giudice are clearly having money issues ... their Jersey Shore home is going up on the auction block Tuesday, and the starting bid is $100 ... TMZ has confirmed.

The home has been in foreclosure and the Giudice's owe $348k to HSBC Banks. If the bank accepts a bid, the buyer has to cough up 20% on the spot, either in cash or certified check.

The house is a little over 1300 square feet.

Although the auction is scheduled today, the Giudice's have thrown a Hail Mary twice before and the sale has been postponed. But as of now, it's set to go up for auction in a matter of hours.
