Ownership & Legal • Long-Term Appreciation

Reaping the Benefits of Holding Property for the Long Term

In most cities, owning a home means keeping pace with inflation. In San Francisco, it has meant something closer to compounding wealth — and returns that would be unheard of elsewhere.

The Long Hold in San Francisco

Where holding actually pays

Let’s face it: this kind of appreciation isn’t available everywhere. Plenty of American markets have moved sideways for a decade. San Francisco has not — over the past thirty years, residential real estate here has appreciated at roughly 7% annually, meaningfully ahead of inflation and well ahead of most U.S. metros. Long-time owners routinely sit on gains of 30–40% or more relative to recent comps.

When it comes time to sell — and if we do our job right (which we will) — you may well have a capital gains issue worth planning for.

With Great Gains Come Great Tax Obligations

The tax bill — and what softens it

Like most every seller, the first question is the same: how much will we sell the house for? The answer is a lot, and more — but just how much, and how much more, is something we can’t predict yet.

Then the other questions arrive. How much will I owe in taxes? How can I limit what I owe?

Combined California and federal capital gains rates typically land in the 34–37% range. And here’s a point that catches sellers off guard: even if you relocate out of state before the sale closes, you’ll still owe California’s Franchise Tax Board — because the property itself sits within the state.

The good news is that there are built-in tax benefits that lessen the blow. The work is in knowing where they are and planning ahead.

A Note Before We Go Further: I'm not a CPA, and you should consult one. But I've worked through these questions many times—with clients, and with my own family's properties. If you need referrals to the right professionals, I'm glad to make introductions.

Back to the narrative.

Selling Your Primary Residence

The capital gains exclusion

If the home you’re selling is your primary residence, you may exclude pre-set amounts of gain under IRS Section 121 — and potentially significantly more once qualifying improvements are factored in. (The full guidance lives in IRS Publication 523 — worth a Google for the details.)

The headline numbers:

Single filers: up to $250,000 of gain excluded
Married/joint filers: up to $500,000 of gain excluded
Requirement: you must have owned and lived in the home for at least 2 of the last 5 years — not necessarily consecutive

The Underlying Math

How capital gains are actually calculated

The IRS and California’s Franchise Tax Board both work from the same equation:

Initial basis: what you originally paid for the home
Adjusted basis: initial basis plus qualified improvements
Final sale price: what the home sells for
Taxable gain: final sale price minus adjusted basis

The higher your adjusted basis, the smaller your taxable gain. Which means the work you’ve done to the house over the years — if it qualifies — is doing real tax work too.
What counts toward your basis

What counts toward your basis

Yes, It's an Improvement

Improvements that add value

Kitchen and bath remodels
New HVAC, roofing, electrical, or plumbing
Room additions or ADUs
Structural and seismic upgrades

Sorry, No...

Routine repairs and upkeep

Painting and patching walls unless it's part of staging
Fixing leaks or replacing fixtures
General maintenance
Cosmetic touch-ups for sale

Keep your receipts. Those records can make all the difference.

Costs at the sale that also reduce your gain

Beyond the improvements made over the years, costs incurred at the sale itself get factored in too:

Real estate commissions
Staging and advertising
Legal fees — including, potentially, tenant buyouts
Escrow and closing costs
Purchase-side seller costs you may have covered at acquisition

For the full list, see IRS Publication 523.

One Timing Note: Capital gains taxes on a sale are due the year after the sale closes — not the year of. That extra runway can matter for planning.

Why Long-Time Owners Stay Put

Proposition 13 and the value of standing still

Since 1978, Proposition 13 has capped annual property tax increases at 2% over the original assessed value — not market value. The result, in a market like ours, is a tax delta that can be staggering between neighbors on the same block.

A Tale of Two Neighbors

Bought in 1985 for $200K

Annual property tax around $3,000.

→

Same home bought in 2024 for $2M

Annual property tax around $25,000.

That difference is the single biggest reason long-time SF owners hesitate to sell. The home itself has done its job. Letting go of the tax basis is the real price of admission.

Proposition 19

Taking your tax base with you

For homeowners 55 or older, the severely disabled, or victims of natural disaster, Proposition 19 is the unlock. It lets you transfer your low Prop 13 base to a replacement home anywhere in California — up to three times in your lifetime.

How it works

Buy a replacement home within 2 years of selling the original
The replacement can be anywhere in California — not just your current county
If the new home costs more, the difference is added to your tax base
The benefit can be used up to three times in your lifetime

How much you can spend before reassessment

Timing of Replacement Purchase

Maximum Value

Before selling your original home

100% of original home's market value

Within 1 year after selling

Up to 105% of original market value

Within 2 years after selling

Up to 110% of original market value

Why This Matters: For decades, the property tax gap has frozen older homeowners in place—even when the house no longer fits their life. Prop 19 is the provision that thaws that. Downsizing, relocating, or moving closer to family no longer means trading a $4,000 tax bill for a $40,000 one.

Investment Property

Different rules apply when it isn't your home

If you’re selling a rental or investment property, the primary residence exclusion doesn’t apply. Instead, you’re looking at:

Capital gains tax — combined federal and California rates can reach ~37%
Depreciation recapture — roughly 25% on the depreciation you previously claimed

The 1031 Exchange

A 1031 lets you defer the entire bill by reinvesting proceeds into another investment property. Done correctly, the tax obligation rolls forward — sometimes indefinitely.

The replacement property must be of equal or greater value
You must identify a replacement within 45 days of closing the sale
You must close on the replacement within 180 days
The funds cannot pass through your personal accounts — a qualified intermediary holds them

For Heirs: When investment property is inherited, the heir receives a step-up in basis to the current market value. Sell immediately and the capital gains liability is, effectively, zero. This is one of the most powerful provisions in the tax code—and a reason careful estate planning matters.

Inheritance & Estate Planning

The federal exemption, the step-up, and Prop 19's new restrictions

In 2025, the federal estate tax exemption is $13.99 million per person ($27.98 million per married couple). Estates above that face a 40% federal tax. California, importantly, has no state estate tax — which is part of what makes real estate here such a durable wealth-building tool across generations.

Prop 19 and inherited homes

Proposition 19 changed the rules for parent-to-child transfers. Two conditions now apply:

The home must become the child’s primary residence within one year of transfer
If market value exceeds the assessed value by more than $1M, the difference is partially reassessed

An Example That Matters

A home bought in 1980 for $300,000 has a current property tax bill of around $4,500 per year.

The home is now worth $2.5 million, but its assessed value still sits near $500,000.

Under the old rules: the child could inherit that $500,000 tax basis—even if they rented the home out.

Under Prop 19: unless the child moves in within a year, the home is reassessed at market value. The annual tax bill jumps to more than $30,000.

The planning implications are real. For some families, this changes the calculus on whether to hold a home for the next generation or sell during the parents’ lifetime.

Trusts & Probate

Keeping your heirs out of court

Most homeowners I work with eventually deed their primary residence into a revocable trust. The reasons are straightforward:

Avoid probate — which is slow, public, and expensive
Ensure a smooth transfer to heirs without court involvement
Maintain privacy around the value and disposition of the estate
Retain full control during your lifetime — revocable means revocable

For married couples, California’s community property rules also handle the simplest case cleanly: when one spouse dies, the surviving spouse inherits the home automatically, without probate.

The Bottom Line

Plan ahead. The biggest wins go to the people who started thinking about this years before they sold.

Take the $250K/$500K primary residence exclusion when it applies
For investment property, look hard at a 1031 exchange before listing
If you’re 55 or older, Prop 19 lets you move without losing your Prop 13 base
A revocable trust keeps your heirs out of probate and preserves privacy
Keep records of every qualified improvement — they raise your adjusted basis decades later
