Agree with Pacita: there is nothing you can do to expedite things â€“ banks work on their own timelines. This can often mess up a close of escrow and greatly inconvenience the buyer. Unfortunately, there is no recourse. You may have a per-diem clause with specific penalties for closing late: as long as it is the bank causing the delays, you will not have to pay any per diem fees.
sometimes, REO banks can take 5-7 days to respond to an offer. And the same goes with their response to documents once you're in contract. Others can respond quicker.
Your agent should keep following up with the REO agent and the escrow company for updates
Hang in there. Your own lender should be aware of these challenges as well and may be willing to work with you on the timelines.
