Short Sale Offer Price and BPO?

[Michael J.]

I am looking at a house that my agent is communicating with the listing agent and is going to be told the BPO price that they come up with.

Once we know what the BPO price is, and if it jives with normal analysis, is there a safe % we could offer to increase the chances of it being accepted?

I read a page or two and depending on the loan type they might accept 80% - 92% of the BPO, does that sound right or is it more random than that? We are in the process of determining the loan type and if there is a second.

If we give a strong, simple offer is there any chance it will speed up the offer? I have read anything from a month to a year.
