Line of Credit Reverse Mortgage 2026: How the Growth Feature Works and Why It Matters

The HECM line of credit has a growth feature that no other credit product offers: unused credit grows over time. Here is how it works and who it benefits most.

The HECM (Home Equity Conversion Mortgage) line of credit is one of the most misunderstood tools in the mortgage industry. Most MLOs know reverse mortgages exist, but few understand the LOC growth feature that makes the product genuinely useful for retirement planning rather than just a last resort for cash-strapped seniors.

How the Growth Feature Works

Any portion of the HECM credit line that is not drawn grows at a rate equal to the loan's interest rate plus the ongoing MIP rate (currently 0.5% annually). This is not growth in the borrower's net worth; it is growth in available credit. A homeowner who establishes a $300,000 HECM line at age 62 and draws nothing will have access to significantly more credit at age 72, assuming the interest rate and MIP components add up over that decade. Critically, this credit line cannot be frozen, reduced, or cancelled by the lender as long as the borrower maintains their obligations: paying property taxes and insurance, maintaining the home, and occupying it as their primary residence.

Why This Feature Is Unique

No conventional HELOC offers a growth feature. Banks can freeze or reduce a HELOC at any time, which many homeowners learned during the 2008 financial crisis when lenders froze lines on underwater properties. The HECM line's non-cancellable nature and growth feature make it a categorically different planning tool, particularly for homeowners who establish it while home values are high and rates are low to lock in a larger credit base for the future.

Who Benefits Most from the HECM LOC

  • Homeowners aged 62-70 with significant equity who want a standby fund for future medical or long-term care expenses
  • Retirees who want to reduce sequence-of-returns risk by having a non-portfolio credit source to draw from during market downturns, preserving the portfolio for recovery
  • Homeowners whose Social Security benefits would be reduced by too-high reported income: HECM draws are not income and do not affect Social Security
  • Borrowers who want to eliminate the mortgage payment in retirement without selling investments to pay off the loan balance

Medicaid Caution

HECM proceeds that remain in a bank account may be counted as a resource for Medicaid eligibility purposes. Borrowers who anticipate Medicaid need should work with an elder law attorney before establishing a HECM line. Proceeds drawn and spent in the same month are generally not counted; retained cash can be.
