Downsizing in Napa Valley: Property Tax Savings, Prop 19 & Capital Gains Explained

I hear it all of the time. As my clients get older, they begin to grow tired of maintaining a large home or property and start asking themselves an important question: Would life be simpler in a smaller home?

For many homeowners, however, the decision to downsize isn't simply about less maintenance or fewer stairs. It's also about finances.

One of the biggest concerns I hear is, "Can I afford to move without losing my low property taxes?" Others wonder whether selling their longtime home will trigger a large capital gains tax bill or affect what they can leave to their children.

The good news is that California's Proposition 19 and the federal capital gains tax exclusion can create significant financial opportunities for homeowners considering a move. Understanding how these rules work can make the difference between feeling stuck in a home that no longer fits your lifestyle and moving forward with confidence.

1. Proposition 19: Transferring Your Property Tax Basis

Passed in 2020, Proposition 19 allows eligible homeowners who are age 55 or older, severely disabled, or victims of a natural disaster to transfer the taxable value of their current home to a replacement residence anywhere in California.

What Is a Property Tax Basis?

Your property tax basis is the assessed value of your home for property tax purposes. Under Proposition 13, this assessed value generally increases by no more than 2% per year, regardless of how much your home's market value appreciates.

If you've owned your home for decades, your property taxes may be dramatically lower than what someone purchasing your home today would pay.

How Prop 19 Helps

Proposition 19 allows eligible homeowners to transfer their existing tax basis up to three times anywhere within California.

Even if your replacement home costs more than your current residence, you don't lose your low property tax base. Instead, your new assessed value is generally calculated by adding the difference in purchase prices to your existing tax basis.

Example

Suppose your current home has an assessed value of $500,000 but is worth $1.5 million in today's market.

You sell your home for $1.5 million and purchase a replacement home for $2 million.

Under Proposition 19, your new taxable value would generally be:

• Existing tax basis: $500,000
• Difference between purchase prices: $500,000

New assessed value: $1,000,000

Rather than paying property taxes based on the full $2 million purchase price, your taxes would be based on the lower adjusted value of $1 million.

For many homeowners, Proposition 19 can result in thousands of dollars in annual property tax savings and make downsizing or relocating far more financially feasible.

2. Understanding Capital Gains Taxes When Selling Your Home

Another major financial consideration when downsizing is the potential capital gains tax associated with selling your primary residence.

Capital Gains Exclusion

Current federal law allows homeowners to exclude:

• Up to $250,000 of capital gains for single taxpayers
• Up to $500,000 of capital gains for married couples filing jointly

To qualify, you generally must have owned and lived in the home as your primary residence for at least two of the previous five years.

How Capital Gains Are Calculated

Your capital gain is generally the difference between:

• The selling price of your home, and
• Your adjusted cost basis, which includes your original purchase price plus certain qualifying improvements.

Example

Suppose you purchased your home many years ago for $200,000 and sell it today for $1.2 million.

Your capital gain would be approximately $1 million.

If you are married and qualify for the full exclusion, you may exclude $500,000 of gain. The remaining $500,000 may be subject to capital gains taxes.

Don't Forget About Home Improvements

Many homeowners overlook the fact that certain capital improvements may increase their cost basis and potentially reduce taxable gains.

Examples may include:

• Kitchen renovations
• Room additions
• New roofs
• Window replacements
• Major landscaping projects
• Solar installations
• HVAC replacements

Keeping records and receipts for major improvements can be extremely valuable when it comes time to sell.

3. Proposition 60 and Proposition 90: What Changed?

Prior to Proposition 19, homeowners over age 55 could transfer their tax basis under Proposition 60 and Proposition 90.

However, these programs had significant limitations:

• Transfers were generally limited to one time only
• Moves had to occur within participating counties
• Purchasing a more expensive replacement home was often restricted

Proposition 19 significantly expanded these benefits by allowing eligible homeowners to:

• Move anywhere in California
• Transfer their tax basis up to three times
• Purchase a more expensive replacement property while still preserving substantial property tax savings

For many homeowners, these changes have created far greater flexibility in retirement planning.

4. Proposition 19 and Leaving Your Home to Your Children

One of the most significant changes under Proposition 19 involves inherited property.

Under previous rules, many families could pass along homes and their favorable property tax basis to children, even if the property became a second home or rental property.

That changed under Proposition 19.

Limitations on Inherited Property

To preserve certain property tax benefits, a child generally must:

• Inherit the property, and
• Use the home as their primary residence.

If the property becomes a rental, vacation home, or investment property, it will generally be reassessed at current market value.

Exemption Limits

Even when children occupy the inherited property as their primary residence, limitations still apply.

If the property's market value exceeds the parent's taxable value by more than $1 million, a portion of that excess value may be added to the property's assessed value.

Example

Suppose you pass away owning a home with:

• Assessed value: $500,000
• Market value: $1.7 million

If your child qualifies and uses the property as their primary residence, they may be able to retain a portion of your favorable tax basis. However, because the difference exceeds the applicable threshold, some of the excess value may be added to the property's assessed value.

Because these rules can be complex, consulting with an estate planning attorney and tax advisor is strongly recommended.

5. Estate Planning and Long-Term Financial Health

Downsizing often creates opportunities to improve both lifestyle and financial flexibility.

Gifting Considerations

As of 2026, individuals may gift up to $19,000 per recipient per year without triggering federal gift tax reporting requirements.

For some families, downsizing creates an opportunity to help children or grandchildren financially while simplifying their own lives.

Improving Financial Liquidity

Selling a longtime home may unlock significant equity that can be used to:

• Supplement retirement income
• Pay off debt
• Fund travel and lifestyle goals
• Assist family members
• Improve long-term financial security

However, it's important to consider how a sale fits into your broader estate and tax planning objectives.

6. Lifestyle and Healthcare Considerations

For many homeowners, downsizing isn't just a financial decision—it's also a lifestyle decision.

Aging in Place

Many clients prioritize homes with features that support long-term living, including:

• Single-level floor plans
• Minimal stairs
• Wider hallways and doorways
• Walk-in showers
• Low-maintenance yards

Access to Healthcare

As healthcare needs evolve, proximity to quality medical facilities and providers often becomes increasingly important.

Community and Social Connections

Retirement can also be an opportunity to find a community that better aligns with your lifestyle and interests.

Many homeowners choose to move closer to:

• Family members
• Recreational activities
• Restaurants and cultural amenities
• Walkable neighborhoods
• Communities with active social opportunities

Frequently Asked Questions

Final Thoughts
