States it's worth $90, I'm asking for $80 so. I think it's quite fair.
If you looked at the digital goods section and the auction section, you will see tons of threads of domain spammers/squatters trying to sell their worthless domains with no luck.
The domain appraiser sites generally are not able to give accurate valuations, at least this is what I understand
The problem here is not only their value but being able to sell it its hard, collaterals should be easy to sell to get your money back in case OP doesnt pay the loan back and as you said a lot of domain auctions and sales are in this forum but no one buys.
