Do you mean wholesaling, where you do a simultaneous close with the seller and with a buyer? 

Of course you can also work with a few agents simultaneously letting each one know they are in competition for your business.Just my two cents in what I would do if in your position.  

Hello, can anyone recommend an investor friendly title company who does simultaneous closings in New York City (Brooklyn, Queens, Manhattan, Bronx)?

After the rehab is done, and you rent it (If buy and hold is your goal) then you can do a cash out refinance simultaneously paying off your lender and putting your HELOC money back.

And she can work the bankruptcy angle while simultaneously trying to sell the home, and/or while trying to borrow the amount past due, etc.  

Your cash flow might be less at the end of the day, but you will open up your criteria a little and may end up with a better property, or two. 1 property that cash flows $600/month or 2 properties that cash flow $300/month.. you could potentially get the same result in the end, while getting in a better market for yourself, and obtaining 2 properties, building equity simultaneously.

@Lynda Duke Lynda, Google Drive is a hub of many different tools in which you can share your activity with others, and edit documents/spreadsheets/etc. simultaneously.

The nice thing about this is you can get the property re-appraised and get the LTV of the new appraised price, after your rehab, and not the appraised value at the time of purchase.In the future, many bank also offer what is know as a simultaneous closing.  

You could simultaneously file suit or countersuit to quiet the title in your name.

Most common is a straight lease option assignment to the tenant buyer or seller where you collect an assignment fee and move on, or a sandwich lease option where you stay in the middle throughout the lease term and typically do a simultaneous/double closing when its time to purchase.
