The HECM line of credit- One of the most overlooked yet beneficial features of the HECM is the line of credit. Unlike traditional home equity lines of credit which can be closed or reduced this special credit line is secured and cannot be reduced if home values decrease or interest rates increase. Even better the unused portion of the credit line increases each month your clients don't use it. The line of credit grows each month based on the current month’s interest rate and ongoing insurance charge. Many older homeowners have set up the line of credit for use by the surviving spouse to offset loss of income and much more.
