I am a bankruptcy attorney and I would be happy to answer your question. First, since you already have an attorney I recommend you obviously defer to him or her regarding a plan of action for your Chapter 11 bankruptcy. However, here are some options that may be available to you and your attorney:
Although the property may be set for a foreclosure sale, you still have time, even if it takes up to the last day before the sale. Debtors in your position can get very anxious with a foreclosure sale looming as is normal, but remember you still have a few weeks and a lot may happen. As soon as the appraisal and funding comes through your attorney can easily prepare a Stipulation Reinstating the Bankruptcy Stay that the creditor's counsel can sign, and then file for the Court's approval. This will prevent the sale and reinstate the Stay. This happens quite often at the very last minute in many bankruptcy cases, sometimes even the same day as the sale. Then the creditor will usually later file a Notice
stating why the stipulation was filed. This can include reasons such as the appraisal, payment of arrears, good faith payment, funding, etc.
With regards XXXXX XXXXX Chapter 11 Plan being filed late, I would recommend filing one as soon as possible! Your attorney may want to file a Motion requesting an extension of time to file a Plan, and then attach a proposed Plan to the Motion along with the appraisal as soon as you receive it. You may even want to file the Motion right now without the appraisal but explain to the Court that your plan is contingent on an appraisal and certain funding and then attach an Affidavit from you personally explaining what steps (the details) you are doing in order to secure such funding.
Lastly, your attorney could file an Emergency Motion to Reinstate the Stay for the Property, which at least may buy you some time before the property is sold. The creditor may oppose it, but at least you can present your argument to the Court and this may prolong the sale a few extra weeks. The Court may grant you and your attorney a temporary stay Order to see if a proposed plan is viable or allow you a few extra weeks to get the funding. Therefore, the Court could continue the hearing while preventing the sale in the mean time.
