If you're a San Mateo homeowner nearing retirement, an existing mortgage can make a reverse mortgage feel hard to figure out. I’ll help you understand what to review before you decide.
How a HECM works
A Home Equity Conversion Mortgage, or HECM, is a reverse mortgage for eligible homeowners; proceeds generally must pay off an existing mortgage and other required liens at closing. In San Mateo, your home’s value and the exact payoff are key details to review.
Questions about your situation?
Talk it through with a loan officer who knows this market. No forms and no pressure.
Start with your mortgage and home details
If gathering paperwork feels like a lot, start with what you already have. You’ll want your current mortgage statement and a payoff statement from your servicer. The payoff can differ from the statement balance because it’s calculated for a specific date and may include other amounts due.
Also gather details about any other liens secured by your home. I’ll review the full picture with you, rather than relying on one balance that may not tell the whole story.
Check whether estimated proceeds could cover the payoff
It’s understandable to wonder whether the numbers will work. Potential HECM proceeds can depend on borrower age, home value, mortgage payoff, program limits, and costs. The details vary, so one estimate won’t fit every homeowner.
The key question is whether estimated proceeds could cover the required payoff and costs. If they can, proceeds may remain, depending on final figures. If they can’t, you may need another way to address the amount due. I can explain the process, but an estimate isn’t a promise of funds or approval. Eligibility and approval are subject to credit approval and program guidelines.
Review the payoff plan and any gap
A possible funding gap can feel unsettling, so it’s worth discussing before you move ahead. If estimated proceeds appear insufficient for the mortgage and required costs, talk with your loan officer about possible next steps. Depending on your circumstances and program rules, other available funds or a different financing approach may need consideration.
I’ll compare your payoff statement with the estimated HECM figures so we can spot questions about the balance or timing early. That comparison can clarify what still needs confirmation, but it doesn’t guarantee proceeds will cover the payoff. Keep your plan flexible until the figures and requirements have been reviewed.
Understand closing and ongoing responsibilities
Closing can feel like a lot of moving pieces when one loan pays off another. If HECM proceeds and any other arrangements are sufficient, the existing mortgage payoff is handled as part of closing. The payoff statement’s timing and final amount matter, so check that the figures are current.
You’ll also have ongoing responsibilities with a HECM. Borrowers generally remain responsible for property taxes, homeowners insurance, home upkeep, and meeting program occupancy requirements. I’ll review your property-related costs and closing estimates with you instead of assuming a general figure applies. Read each document carefully, and ask for a plain-language explanation if anything feels unclear.
Decide whether the structure fits your plans
Choosing a path can feel like a big decision because it affects more than your mortgage balance. Compare your current obligations with the HECM’s costs, responsibilities, and effect on the home equity available to you. Consider how the arrangement fits your broader budget and housing plans, including funds you want to keep available for other needs.
I’ll help you understand what the proposed structure means before you choose a path. Having an existing mortgage doesn’t automatically rule out exploring a HECM, but the payoff amount, closing costs, and eligibility details matter. With the figures in view, you can make a more informed decision. Qualification and approval are subject to credit approval and program guidelines.
San Mateo home values call for a closer look
If you’re trying to understand what your home might contribute to the decision, a local benchmark can offer context. San Mateo’s median home value is $1,494,500, according to the Census ACS 5-Year (2023). I’ll focus on your home’s actual details with you; this county figure isn’t a valuation or a calculation of available proceeds.
Your home’s value is personal to your payoff question
It’s natural to look for a quick estimate, but your own home’s details matter most. San Mateo’s home value is $1,674,908, according to Zillow Research (September 2026). I’ll use that only as market context, not as a valuation of your home or an estimate of HECM proceeds.
Keep property taxes in your ongoing-cost review
Ongoing costs deserve attention when you’re weighing a reverse mortgage. The median property tax in San Mateo County is $9,167, according to the Census ACS 5-Year (2023). You remain responsible for property taxes with a HECM, so I’ll help you include your own tax bill in the broader review.
Put local values in context, not in place of an estimate
It can help to see how local home values have been moving, while keeping your own plans front and center. San Mateo home values changed by -0.61% year over year, according to the FHFA House Price Index (2025). I’ll treat that as market context, not a forecast or a substitute for reviewing your home and payoff.
Consider the local ownership picture
You may want to know how common homeownership is around you. The homeownership rate in San Mateo County is 59.09%, according to the Census ACS 5-Year (2023). I’ll keep that broad context separate from your individual eligibility and payoff review.
Review your own budget alongside county income context
Thinking about costs beyond the mortgage can feel important as retirement approaches. The median household income in San Mateo County is $156,000, according to the Census ACS 5-Year (2023). I’ll use that only as local context; your own resources and ongoing obligations matter for your planning.
