Has anyone negotiated a redemption amount after foreclosure sale?

[Pavel Sakurets]

I bought a property/deed from the seller whose house was foreclosed on and I intend to redeem the property from the sheriff before redemption rights expire. Now i'm trying to negotiate with Ditech to pay them less for the redemption certificate that they bought at sheriff's sale.

Has anybody tried doing it before?

Here are the numbers:

To redeem a property (me as a buyer) from the sheriff I need to pay 150k

The property is in bad shape and only will sell for 100k.

I want to pay to the sheriff only 80k to redeem it, but need to get an approval from Ditech. Has anybody tried doing it that before?
