Depending on what happens to the Florida property, if the bank does foreclose and realizes less than is owed to it, it is possible that it will pursue a deficiency judgment against you. If it does, this may result in a judgment in Florida, which could probably be transferred to IL. State law would control which of your assets would be subject to levy by the bank. In many states, retirement accounts are exempt. Normally, bank accounts are not exempt.
Your best best is to speak to an attorney in Illinois so see which of the assets there could be susceptible to a deficiency judgment levy.
Just to add another point to the previous answer, you should have someone review the mortgage on the investment home. It is often the case that prople who purchase investment property utilize the same lender as they have for their primary residence. It is not uncommon for such a lender to add a cross default provision in the mortgage that essentially says that if you default on the mortgage for the investment property, it is considered a default on all other loans you have with that bank.
