First,
Second, I haven't read through all the responses, so this may have been addressed already.
Foreclosures do vary from state to state. In MD, it can take as little as 2 months. In DE, it can takes YEARS. I'm not sure about NY.
When the home goes into foreclosure you will receive a notice (actually, you should receive a demand letter prior to foreclosure. You will be given an amount to pay to bring it current. If you can't, then it will go to foreclosure).
After it is in foreclosure, you can either reinstate (bring current) or payoff. You can try to sell the home will it is in foreclosure, so you can look into that route.
Depending on the state, notices will be filed in the paper, so you may have people calling you or coming to look at the property (they want to see what it looks like in case they buy it at the foreclosure sale).
There may be people offering to reinstate the loan for you, but be VERY CAREFUL. Usually, they will reinstate the loan and you will then have to pay them back. If you default, the home goes to them (no foreclosure). They may also offer to buy your home, and then let you rent. Again, be very careful.
If the home goes to sale and is bought the new owners should notify you of when to be out. If you don't go willingly, they will begin eviction proceedings. This can also happen if the home reverts back to the bank. Again, eviction proceedings can vary as to the time.
It never hurts to speak to the bank and explain the situation. Many times, they will be willing to work with you and set up payment arrangments (either rewrite the mortgage or just have a separate agreement in regards to the payment). I know you aren't in a conventional mortgage, but you can still try and make arrangements.
Now, since you have an attorney, he will need to be the one contacting the attorney handling the foreclosure. If you aren't happy with your current attorney, you need to find someone else.
The above information is what happens in a standard foreclosure. Since you also are in a BK, then some of this may change. You need to speak to an attorney though.
(I used to work for a bankruptcy attorney for the bank. If you need more information I am happy to help, but I don't have experience with NY, only DC, MD, VA, DE, and WV).
Good Luck.
