贡献贴: loan assumability
most ARMs are written to allow creditworthy purchasers to assume them from the seller. after the interest rate discounts offered in the first few years are eliminated, ARMs track current interest rates, and lenders have nothing to lose by someone assuming your loan. in contrast, fixed rate mortgages (except those that are government-backed) are not normally assumable and usually must be paid off in full when a house is sold.
