You just found the right guy for this one:)
I just ran a short sale transaction, same bank, same deal with a 2nd held by a "B of A Investor". This is code for, it's gonna take a long time:) My transaction took 10 months to close, all because B of A couldn't get their crap together. We closed that one in July. We hung in there and managed to get it done. If you really like the house you're trying for, it'll be worth it....
One new tool I found out about during the process was Twitter. All the big companies have a social media presences today and B of A is no exception. I found that the Twitter feed @BofA_Help gives you a direct line to the bank. What did I use this for as the buyers agent? When the asset manager that the listing agent was connected to decided to stop returning phone calls and went a week or two with no contact, I would fire or a Tweet to BofA_Help (including the home address) and ask them tell contact the asset managers boss, and let them know the asset manager is ignoring the transaction/agents.
We were actually successful in replacing the asset managers, twice, for in-action. I don't think my buyer would have hung in there had we not used this little tool. But it all worked out and we managed to get it closed. My only recommendation, if you choose to do this is, make sure both buyer and sellers agent are on the same page and coordinate this contact together. The buyer or the buyers agent can initiate this Twitter thing, but the bank is only authorized to speak with the sellers agent, so get everyone on the same page first.
I hope this helps!
