Submitting a Letter w/ Comps to Bank Owned Properties & Short Sales

My area of expertise is in an area known as Happy Valley where literally 1 out of 4 homes (Big McMansions I might add) are short sales. My buyer wrote a very low offer on a home there. The listing agent seems unfamiliar with the short sale process and worse yet unfamiliar with the area. This home was overpriced, especially for a short sale which explained why she had yet to collect an offer (most short sales in the area are priced so low they attract numerous offers). Anyhow, I asked if she'd mind if I submitted a letter and comps to support our low offer and she seemed overjoyed that I offered and in fact encouraged it. After submitting the information both her and the bank were amazed to see the data and what it suggested. What I was told would be a verbal counter in less than a week has turned into weeks and she says they are uncertain what to do.... I suspect they are requesting another appraisal.... (many of these banks are going off dated appraisals from 6 months back).

I believe that providing the market data and comps was our offer, especially considering how overpriced it is was a good decision. I'm curious if other agents out there do something similar..... ? -Kristie
