what to pay a broker?

[Tal Eisenberg]

So my partner and I are passing on a property that is going to auction. I am also a licensed broker and have a client who this is perfect for. As I understand, the noteholder doesn't pay a broker fee. The buyer is willing to pay a broker fee if he wins the auction. I have done a lot of the work, doing comps, checking title/liens etc. What do you think is a fair amount?

Thanks,

T
