How does HUD choose its listing agent/office/broker?

[Michael Stole]

Now, I know how banks choose their listing agent/office/broker, they look (by maps, google, all means..) for offices within a certain distance from the property, and ask for a broker's price oppinion (BPO) from each of them, and choose the one gives the highest BPO. And if they are satisfied with that office, they will stick with it.

But how does HUD choose its listing agent or office? the same procedure?
