 In some countries with currencies that tend to depreciate, foreign currency mortgages are common, enabling lenders to lend in a stable foreign currency, whilst the borrower takes on the currency risk that the currency will depreciate and they will therefore need to convert higher amounts of the domestic currency to repay the loan.In addition to the two standard means of setting the "cost" of a mortgage loan (fixed at a set interest rate for the term, or variable relative to market interest rates), there are variations in "how" that cost is paid, and how the loan itself is repaid.Repayment depends on locality, tax laws and prevailing culture.
