The bank is interested in the property they have invested in. Usually each property is taken individually (unless for some reason, you have taken a loan out on all properties acollectively, at once, and if so, you really should be talking to a real estate lawyer)...but otherwise, they will foreclose only on the property that has gone into default.
Have you considered selling your home prior to that point? We specialize in such cases and would be happy to offer a free no obligation consulation. All you have to do is ask! Check out our website and see how we can help you http://(www.myLARealEstateGroup.com).
Good Luck to you

I'm so sorry for your trouble...you should call a real estate attorney and ask them. There is a discussion board online (similar to Trulia) for legal questions. Attorneys answer the questions.
Have you tried to sell your home? Tried a short sale?
