Why do some lenders not disclose min bid with court foreclosure ?

questions concerning Florida court foreclosure auctions

I am curious about why do some lenders disclose/show their minimum bid/reserve price at the court auction and some hide it. is it because their want money quicker to move on , and don't have the time to find agents to resell the property on the MLS, or on site like auction.com, hubzu and come etc etc ? or do they think it will attract more money than the judgement . I am just baffled.

second question, I also noticed some florida counties like Volusia for example discloses the minimum reservice price. it looks like the lenders in this county cannot hide their reserve. why is this ?
