If you have a 1st mortgage that has no 2nd, you credit bid, pay the DIP, and take over the property.
If you have a 1st mortgage with a 2nd mortgage, you can credit bid, pay the DIP, and take over your property. In this scenario, the 2nd mortgage holder could credit bid to pay you out. They would pay your principal, interest, fees, everything that is owing to you, and the DIP. If you have a small 1st with a larger 2nd, this might make sense for them. If you have a large 1st with a smaller 2nd, they might just take the loss.
