@valued-customer: If they change the currency and you can't get dollars to pay the payments, you will be in default, not them. Also, I had a bank 'just change the rules half way through it.' Citi bought my lender. Citi just decided I was going to be paying a totally different mortgage contract than the one I signed. A lawyer told me he'd be happy to take on the biggest bank in the world. He'd need $5k upfront so he could start doing research and file some papers, and he expected he'd need that every year for the subsequent 10 or fifteen years, while their lawyers continually threw paper at the court. In the meantime, I needed to make the new payment, at a higher interest rate and more $ per month, or they'd foreclose on my house. They foreclosed on that new mortgage, and took my house. The courts are not on your side against the banks. The courts are designed to give the banks all the power necessary to take whatever they want. Thanks!
