On an adjustable-rate HECM, the portion of your line of credit you have not used grows every month at the note rate plus the 0.5% annual FHA mortgage insurance premium. This tool projects that growth so you can see what leaving the line untouched could make available later.

What is a HECM line of credit growth feature?
The growth feature is written into the HECM program at 24 CFR 206.19(f): the unused portion of the credit line increases at the same rate the loan balance accrues, which is the note rate plus the annual mortgage insurance premium. That is why the line is often described as a standby resource — the longer it sits unused, the more borrowing capacity it holds.
The distinction that matters for planning is that growth is availability, not money. Nothing accrues in your favor until you draw, and once you draw, the amount drawn becomes a loan balance that accrues interest and insurance until the loan is repaid.

Expert insight from Simply Approved Mortgages
Households that open a HECM line early and leave it alone are using it the way it was designed: as sequence-of-returns protection. Drawing from the line in a down market instead of selling investments can preserve a portfolio, and the unused line keeps growing while it waits.
The trade-off to weigh honestly is cost. You pay upfront insurance and origination to establish the line, and if you never use it, you paid for an option you did not exercise. That comparison belongs in the conversation before you apply, not after.

HECM line of credit growth — FAQ
- How fast does a HECM line of credit grow?
- The unused portion of a HECM line of credit grows monthly at the same rate the loan balance accrues — the current note rate plus the 0.5% annual FHA mortgage insurance premium. If the note rate is 7.0%, the unused line grows at roughly 7.5% per year, compounded monthly.
- Is line of credit growth the same as earning interest?
- No. Growth increases the amount of credit you are contractually allowed to draw. It is not interest paid to you, it is not cash, and it is not income. Anything you draw becomes a loan balance that accrues interest and mortgage insurance.
- Can the lender freeze or cancel my HECM credit line?
- For an FHA-insured HECM, the unused line cannot be frozen, reduced, or cancelled because home values fell or the lender's circumstances changed, as long as you meet loan obligations. That is a core difference from a HELOC, where the lender can suspend the line.
- What happens to growth if I take a draw?
- Draws reduce the unused line, so future growth applies to a smaller base. The loan balance you created grows at the same rate, which is why leaving the line untouched is what makes the feature valuable.
- Does the growth rate change over time?
- Yes, on an adjustable-rate HECM. The growth rate follows the note rate, so it rises and falls with the index. A fixed-rate HECM has no growing line of credit at all, because fixed-rate HECMs are available only as a single full draw at closing (lump sum only).
- Are the numbers in this tool guaranteed?
- No. They are educational projections using a rate assumption you select. Future index movement is unknown, and your actual line, rate, and available draws are set by the lender and HUD program rules.
- Do I still owe property charges if I never draw?
- Yes. You must continue paying property taxes, homeowners insurance, HOA dues if applicable, and maintain the home as your primary residence regardless of whether you draw funds.

Why we pull credit for your reverse mortgage pre-approval
HUD requires a Financial Assessment for every HECM reverse mortgage, including a review of your credit history and record of paying property taxes and homeowners insurance. As part of our standard broker/lender pre-approval process, we typically order a tri-merge credit report through a HUD-approved credit vendor to verify identity, review obligations, and confirm that you can continue paying property taxes, homeowners insurance, and maintenance after closing. Whether a tri-merge is required, and any fees, are set by the wholesale lender and credit vendor — not by HUD as a stand-alone rule.
Pay for your credit report — SmartPay
Simply Approved Mortgages uses MeridianLink SmartPay to securely collect the credit report fee for your reverse mortgage pre-approval. Payment goes directly to the credit vendor — not to us — and unlocks a tri-merge credit report (Equifax, Experian, TransUnion) that your loan officer uses to complete the broker/lender pre-approval file for HUD's Financial Assessment.
- Secure, PCI-compliant checkout hosted by MeridianLink
- Standard step in our broker/lender pre-approval process (not a HUD stand-alone requirement)
- Optional — you can decline; your loan officer will explain any impact on your options
