Someone once asked if they could 'compel' the lender to foreclose. No, you can't. You have liability on the property until such time that the lender CHOOSES to execute their foreclosure option. Until such time, if someone trips or falls, you are liable. If your county or city files penalties against the property for it not being maintained you are liable.
With all of the options available, why would you not short sale the home instead? Take control of the timing of the process, have better results in terms of its affect on your credit, job opportunities and peace of mind, and be able to move on without fear of further collections from unpaid billings during the time that you owned the property. In a short sale, all bills are cleared. Go to AskSueArcher.com for options available to you. Good luck.
