Bid price discount in North Carolina?

[A W]

I am trying to bid a couple HUD properties in NC. As I am a newbie in HUD property, I wonder what is the realistic price I should bid in NC for HUD property? I read 70-90% of the listing price and it varies from region to region.. therefore a more accurate number will be very helpful..

both of the properties have been on market for over a month and both have reduced price once 10%.

Many thanks.
