Rollover mortgage – in the law of Contracts, this term refers to a mortgage loan with interest, which has been signed to be re-negotiated every several years. Usually with such mortgage loans the lenders want to secure their profit in case the interest rates increase after giving the loan. Theoretic say that such mortgage agreement would benefit the borrower (the debtor) if the interests drop, but yet it is extremely rare to see reduce of interest rates in our modern world.
