The product
What is a Jumbo Reverse Mortgage?
A jumbo reverse mortgage — also called a proprietary reverse mortgage — is a private loan designed for homes above the $1,249,125 FHA limit. Like a HECM, it requires no monthly mortgage payment while you live in the home as your primary residence.
Unlike a HECM, jumbo products have no FHA lending limit — your full home value is used. Most are available starting at age 55, carry no FHA mortgage insurance premium, and include a line of credit that grows at a fixed rate (typically ~1.5% annually). The tradeoff: interest rates are higher (typically 9%+) and the LOC grows more slowly than a HECM LOC at current rates.

Why HECM wasn't an option here: The HECM principal limit on a $3.6M home is capped at $503,397 (FHA limit × PLF). Sarah's mortgage payoff alone is $1,272,430 — the HECM couldn't even cover it. The jumbo product's $1,447,200 principal limit covered the payoff and left $159,630 in a growing line of credit. No monthly payment. No FHA MIP.

LOC strategy
Both have a growing line of credit — but they grow differently
A common misconception is that jumbo reverse mortgages don't have a line of credit feature. Many do — but the LOC grows at a fixed rate (typically ~1.5% annually), not at the HECM's variable rate-plus-MIP formula. At current rates, a HECM LOC grows at approximately 6.75% per year, compounding monthly.
What this means in practice: if you have a $950,000 home and are choosing between HECM and a jumbo product, the jumbo starts with more available funds ($213,383 vs. $154,700 in a recent verified scenario) but the HECM LOC will catch up in approximately 4–5 years at current rates due to its faster growth. For a $3.6M home with a large payoff, HECM isn't viable — the comparison doesn't apply.

Decision framework
When each option actually wins
Choose Jumbo when…
Jumbo / Proprietary
- Home value is $1.25M+ and maximum cash is the goal — HECM is capped at the FHA limit, jumbo calculates against full home value
- You are age 55–61 (too young for HECM)
- Your mortgage payoff exceeds HECM's principal limit
- No upfront MIP saves $25,000+ on high-value homes
- Fixed rate preferred over HECM ARM
- Condo not FHA-approved
Choose HECM when…
FHA-Insured HECM
- Home is $1.25M+ but maximum cash is not the goal — HECM offers a lower rate and a faster-growing LOC
- The line of credit growth feature may play an important role in your decision — ask your financial planner which product best fits your long-term plan
- FHA non-recourse guarantee important to you or heirs — jumbo products may include non-recourse language but it is contractual, not government-backed
- CFP is modeling HECM as buffer asset — LOC growth rate is core to the strategy
- HUD counseling and standardized terms preferred
Common questions
Jumbo Reverse Mortgage: FAQ
Does a jumbo reverse mortgage have a line of credit that grows?
Yes. Many jumbo reverse mortgage products include a line of credit that grows at a fixed rate of approximately 1.5% per year, with a $20/month servicing fee drawn from the LOC. The growth rate and structure differs from a HECM LOC — ask your financial planner or originator to run a comparison using actual amortization schedules for your specific scenario.
When is a jumbo reverse mortgage the only option?
When the existing mortgage balance exceeds the HECM principal limit — which happens on high-value homes with significant debt. On a $3.6M home, the HECM principal limit is approximately $503,000. If you owe $1.27M, the HECM simply cannot cover the payoff. A jumbo product's higher principal limit makes the transaction possible. Similarly, if you are between ages 55–61, HECM is not available — jumbo is your only option.
Why is the jumbo rate higher than HECM?
HECM rates are influenced by FHA insurance backing and the CMT index plus a lender margin. Jumbo reverse mortgages are private products without government backing, so they price at a higher fixed rate — typically 9–10%. Despite the higher rate, the elimination of the 2% upfront FHA MIP (which can be $25,000+ on a $1.25M loan) often means the jumbo produces more net available funds on high-value homes.
What is the minimum age for a jumbo reverse mortgage?
Most jumbo reverse mortgage products are available starting at age 55, compared to 62 for a HECM. This makes it the only reverse mortgage option for homeowners aged 55–61 with high-value properties.
Is a jumbo reverse mortgage non-recourse like a HECM?
Most jumbo reverse mortgage products include non-recourse language — meaning you or your heirs will never owe more than the home is worth at the time of sale. However, this protection is contractual (not FHA-backed), which is why it is important to work with a reputable lender and understand the specific contract terms. HECM's FHA non-recourse guarantee is backed by the federal government.
