What Is a Reverse Mortgage (HECM) and How Does It Work?
A Home Equity Conversion Mortgage (HECM) — commonly called a reverse mortgage — is a federally-insured loan backed by the FHA that allows homeowners 62 and older to convert part of their home equity into cash, a credit line, or monthly income. Unlike a traditional mortgage, you make no monthly payments. Instead, the loan balance grows over time and is repaid when you sell the home, permanently move out, or pass away.
For Bay Area homeowners, the HECM can serve two distinct strategic purposes: as a seller-side tool to unlock equity in a home you plan to stay in, eliminating your mortgage payment while tapping retirement income; and as a buyer-side tool (HECM for Purchase) to acquire a new home with no mortgage payment required — a powerful strategy for buyers moving into 55+ communities like Rossmoor in Walnut Creek.
How a HECM Works if You're Staying in Your Current Home
If you own your Bay Area home and want to tap equity without selling or taking on monthly debt service, the HECM is worth understanding. The loan amount you qualify for is determined by three factors: your age (the younger you are, the smaller the loan relative to home value), the appraised value of your home (capped at the FHA national HECM limit — $1,149,825 in 2024, verify 2026 at hud.gov), and the current expected interest rate.
HUD publishes Principal Limit Factor (PLF) tables that translate age and rate into the percentage of home value you can borrow. At age 72, the PLF is roughly 50–55% depending on rates. On a $1.6M Bay Area home capped at the $1,149,825 HECM limit: a 52% PLF yields a ~$598K gross principal limit. After paying off any existing mortgage and closing costs (~$15K–$25K), net available proceeds might be $350K–$500K — available as a lump sum, line of credit, or monthly income stream, with no payment required until you leave the home.

The line of credit option has a unique feature: the unused portion grows at the loan's interest rate each year, giving you access to more funds over time. If interest rates rise, your line grows faster. This "LOC growth" is a distinctive advantage over HELOCs, which lenders can freeze or reduce in a downturn.
HECM for Purchase: A Buyer Strategy for 62+ Buyers
HECM for Purchase lets buyers 62 and older use reverse mortgage proceeds to buy a new primary residence — in a single transaction. Instead of making a down payment and taking a traditional mortgage with monthly payments, you provide the required down payment (typically 40–60% of the purchase price, depending on age and rates [VERIFY with current PLF tables]) and the HECM covers the rest. No monthly mortgage payment is required on the new home.
This is particularly powerful for Bay Area retirees downsizing from a $2M+ home to a $800K–$1.2M home in a 55+ community. Example: sell your Cupertino home for $2M (net ~$1.5M after costs and mortgage payoff). Buy a Rossmoor townhome for $900K using HECM for Purchase. Required down payment at age 74: ~$400K (rough estimate [VERIFY]). Remaining cash from sale: ~$1.1M for retirement. Monthly mortgage payment on the new home: $0. This strategy maximizes retirement liquidity while eliminating housing cost from monthly cash flow.
Comparing a Reverse Mortgage to a HELOC
Both tools let you tap home equity without selling. The right choice depends on your income, goals, and how long you plan to stay.
- HELOC: Lower upfront cost (~$500–$2,000), revolving flexibility, but requires monthly interest payments on drawn funds. Best for borrowers with steady income who want short-term equity access while preserving their first mortgage rate. See the HELOC calculator for current rate and payment estimates.
- Reverse Mortgage: No monthly payment required, but higher upfront costs (~$15K–$25K), loan balance grows over time, and the loan must eventually be repaid. Best for cash-poor / asset-rich retirees who want to stay in the home and eliminate housing cash outflow entirely.
Age and income are the primary dividing lines: if you have consistent income and are under 70, a HELOC is often simpler. If you're 72+ with limited monthly income and significant home equity, the HECM's zero-payment structure may be worth the higher upfront costs.
The HECM Non-Recourse Guarantee
One of the most misunderstood aspects of the HECM is its non-recourse feature: you (and your heirs) can never owe more than the home's value at sale. If the loan balance grows to exceed the home's value — for example, if you live in the home for 25+ years and home values fall — FHA's mortgage insurance fund covers the shortfall. Your heirs are not personally liable. This makes the HECM fundamentally different from a traditional mortgage or HELOC, which require full repayment regardless of what the home is worth.

What Happens When You or Your Heirs Need to Repay the HECM
The HECM becomes due and payable when the last borrower permanently leaves the home — through sale, moving to a care facility, or passing away. Heirs typically have approximately 6–12 months to decide [VERIFY timeline with your servicer]: they can sell the home and use proceeds to repay the loan (keeping any excess equity), or refinance into a traditional mortgage if they want to keep the home. Because of the non-recourse guarantee, if the sale price falls short of the loan balance, the FHA insurance covers the difference — heirs don't owe out of pocket.
HECM Costs: What You're Actually Paying
HECM closing costs are higher than most loans [VERIFY all costs with your lender]:
- Upfront MIP: 2% of the appraised value (up to HECM limit) [VERIFY]
- Ongoing MIP: 0.5% per year of the loan balance [VERIFY]
- Origination fee: Up to $6,000 [VERIFY current cap]
- Third-party costs: Appraisal, title, escrow, recording — typically $3,000–$6,000
- HUD counseling: ~$125–$200 (mandatory before application) [VERIFY]
- Total estimate: $15,000–$25,000 [VERIFY — varies significantly by home value and lender]
These costs can typically be financed into the loan, meaning you may not need to pay them out of pocket. Compare using the property tax estimator to understand your full annual carrying costs, and the refinance calculator to evaluate whether a traditional cash-out refi makes more sense at your loan size.
Is a Reverse Mortgage Right for You?
A HECM is worth exploring if you are 62 or older, own your home (with limited or no mortgage remaining), plan to stay in the home for several more years, need to supplement retirement income or eliminate your mortgage payment, or want to buy a new home without a monthly mortgage payment (HECM for Purchase). It is generally not the right fit if you plan to move within 3–5 years (the upfront costs are hard to recoup), want to leave maximum equity to heirs, or have strong income and prefer the flexibility of a HELOC.
