A second or junior mortgage with a face value of both the amount it secures and the balance due under the first mortgage. The mortgagee under the wrap-around collects a payment based on its face value and then pays the first mortgagee. It is most effective when the first has a lower interest rate than the second, since the mortgagee under the wrap-around gains the difference between the interest rates, or the mortgagor under the wrap-around may obtain a lower rate than if refinancing.
