Reverse Mortgages and LA Property Taxes (Prop 13 Explained)
If you've owned your LA home since the 1980s or 1990s, your Prop 13 basis is one of the most valuable financial assets you have. Here's exactly how a reverse mortgage interacts with it — and why most LA homeowners are surprised that the answer is so simple.
Quick refresher on Prop 13
California Proposition 13, passed in 1978, caps annual property tax increases at 2% of your assessed value. The assessed value is set when you buy the home (or do certain qualifying improvements). It does not move with market value.
Practical effect: an LA homeowner who bought in 1985 for $200,000 might still be assessed at roughly $370,000 today, even if the home is worth $1.8M. Their annual property tax is around $4,000 instead of the $19,000 a new buyer would pay.
For long-tenure LA homeowners, this is a substantial financial asset — one that's quietly worth $10,000 to $20,000+ per year in tax savings, indefinitely.
The big question: does a reverse mortgage trigger reassessment?
No. A reverse mortgage is a loan against your home, not a transfer of title. You stay on title. The home doesn't change ownership. There's no transaction that triggers a Prop 13 reassessment.
Your Prop 13 basis stays exactly where it is. You continue to pay property taxes on your existing assessed value, with the same 2% annual cap. Your tax savings continue uninterrupted.
The contrast: what selling does
If you sell your LA home and buy a different one, the new home is assessed at full market value. You start fresh with a new Prop 13 basis at today's prices.
For long-tenure LA owners considering a downsize, this is often the deciding factor. A 75-year-old who sells a $1.8M home (with $370K basis, $4K annual tax) and buys a $1.2M home would pay roughly $14K annually on the new home — a $10K/year tax increase, indefinitely.
Prop 19 (2021) created a partial fix: homeowners 55+ can transfer their Prop 13 basis to a new primary residence under specific conditions, blended with the new home's assessed value if it's worth more. But the rules are restrictive and don't always pencil. Many LA seniors who run the math find that downsizing actually increases their property tax bill.
Why this matters for the reverse mortgage decision
For an LA homeowner trying to decide between a reverse mortgage and a sale-and-downsize, the Prop 13 math often tips heavily toward the reverse mortgage:
- Reverse mortgage = stay on title, keep Prop 13 basis, no new tax bill
- Sale + new home = new Prop 13 basis at current market, often $10K+/year more in tax
Over a 20-year retirement horizon, a $10K/year tax increase is $200K of preserved wealth that never gets to your heirs. That's a meaningful number.
What happens to property taxes during the reverse mortgage
You continue to pay them yourself. The lender does not pay your property taxes. (You can choose to set up impounds for taxes and insurance through a separate arrangement, but it's not built into the loan.)
This is a borrower obligation under the reverse mortgage. Failing to pay property taxes can trigger default, just like any other mortgage. The financial assessment at application confirms that you have the resources to keep up with property taxes throughout the loan.
Common questions
Does adding a co-borrower trigger reassessment? Adding a spouse who's already on title doesn't. Adding a non-spouse can in some cases — we walk through this carefully if it's relevant.
Does refinancing the reverse mortgage trigger reassessment? No. Refinancing a loan doesn't change ownership.
What if I do a HECM for Purchase on a different home? The new home is a new purchase and gets assessed at full market value. If you're 55+, Prop 19 may let you transfer your basis (with adjustments). We can connect you with a CPA or tax advisor for the specific calculation.
What about my heirs and Prop 19? Prop 19 changed inherited property rules. Children inheriting a parent's home can no longer keep the parent's Prop 13 basis unless they make it their primary residence (with limits). This is independent of whether the home has a reverse mortgage. Worth discussing with your estate planner.
Bottom line for LA homeowners
Your Prop 13 basis is preserved. A reverse mortgage doesn't touch it. For long-tenure LA homeowners specifically, this is one of the strongest arguments for using a reverse mortgage instead of selling — the tax math protects substantial wealth that selling would unwind.
Run the comparison: 20 years of preserved property tax savings vs. the cost of the reverse mortgage. For most long-tenure LA homeowners, the math heavily favors staying.
