Homeowners with two mortgages or those who used 100 percent financing to purchase their residences and are now trying to negotiate a short sale may be facing even more trouble in the future.

Short sales, when a property is sold for less than what is owed on the mortgage, have become more common because properties values have plunged and more homeowners are facing foreclosure.

Short sale deals involving a primary mortgage and second mortgage have always been tougher to hammer out.

But in the past, homeowners with two loans who were trying to avoid foreclosure have been able to negotiate short sales deals where the second mortgage holder gets a small amount or nothing at all.  

Now, second mortgage holders aren’t as willing to agree to such deals.

A recent story in BusinessWeek noted that Bank of America, is requesting homeowners to fork over as much as 5 percent of the sale proceeds in transactions where the bank holds the second mortgage.

Those are tough terms for already-stretched borrowers to accept.
