Key takeaways
Summary: Choosing an agent to help you downsize in Silicon Valley comes down to whether that agent understands the full transition, not just the sale. Seb Frey has organized his Compass practice around longtime homeowners and their families, backed by senior-focused designations, a 2024 REALTOR® of the Year award, and two decades of local transactions. His process covers pricing and preparing an older home, timing the replacement purchase, using Prop 19 and the home sale tax exclusion, and coordinating with agents and move managers when clients relocate.
Sebastian Frey has completed more than 470 real estate transactions representing over $280 million in career sales, and that kind of track record takes years to build. Still, finding the best real estate agent for downsizing in Silicon Valley, CA comes down to one question: does the agent understand what you're actually dealing with? Selling a home you've owned for 30 or 40 years is a different animal than a standard transaction, and the logistics alone can derail everything if your agent isn't paying attention. Seb has built his practice around that transition, which means the timing, the coordination with family and outside professionals, and the job of moving out of a long-held home without things falling apart in the middle.
Why Sebastian Frey Is a Strong Choice for Downsizing in Silicon Valley
In January 2025 the Santa Cruz County Association of REALTORS® named Seb its 2024 REALTOR® of the Year. It's a peer award rather than a sales award, so it reflects how other agents see the way he does business. His focus is also narrower than most agents'. He works mainly with longtime homeowners between 60 and 80 who are selling a high-value property, often one carrying a large capital gain after decades of ownership, and who need to land somewhere smaller on the other side.
He has the training to back that up. Seb holds the SRES® designation from the National Association of REALTORS®, which focuses on the financial and housing needs of sellers 50 and older, and he's a Certified Senior Advisor (CSA), a credential from the Society of Certified Senior Advisors that covers the health, financial and family side of aging. None of that is a niche he stumbled into. Selling after decades of ownership usually means deferred maintenance, adult children weighing in from different time zones, emotional weight, and the very real problem of buying a replacement home while you're still living in the one you're selling. Seb builds his process around those friction points so an inherently disruptive move stays as manageable as possible.

How Seb Approaches a Downsizing Sale
Most of the risk in a downsizing move comes from the order things happen in. Seb starts by helping clients figure out what the house is likely to sell for, what repairs are actually worth doing, and what the after-tax proceeds will look like, because that number decides what the next home can be. From there he maps out whether it makes more sense to sell first, buy first, or try to close both at the same time. If you sell first, a rent-back after closing can give you weeks or months to move without paying for a second place. If you buy first, bridge financing can unlock your equity before the old house sells. He walks through both paths in more detail in his guide on how to sell your home and then buy another.
Taxes get the same attention. Under California's Prop 19, homeowners 55 and older can transfer their Prop 13 property tax base to a replacement home anywhere in California up to three times, as long as the new home is bought within two years of the sale. That can save a downsizer thousands of dollars a year, and you can run your own numbers with Seb's Prop 19 calculator. On the federal side, IRS Publication 523 lets you exclude up to $250,000 of gain ($500,000 for married couples filing jointly) on a primary residence you've owned and lived in for two of the last five years. Silicon Valley homeowners who bought in the 1980s or 1990s often blow past that limit, so it's worth checking the capital gains tax calculator and talking with your CPA before you list. Seb isn't a tax advisor, but he makes sure these questions get asked early, while there's still time to plan around them.
Preparation is the last big piece. Older homes almost always need some work before they hit the market, and Seb connects sellers with local contractors, stagers, cleaners and senior move managers so families aren't spending weekends tracking people down. For sellers who'd rather not pay for repairs out of pocket, Compass's Market Ready Concierge program gives eligible sellers access to up to $75,000 for staging, painting, repairs and moving, with nothing due until the home closes.

Proven Results and Track Record
Over the past 12 months, Seb closed 24 transaction sides and generated more than $26 million in sales volume. His full career record covers more than 470 real estate transactions and over $280 million in sales, built over 23 years of full-time work in Silicon Valley and Santa Cruz County.
The industry has noticed. RealTrends ranked him among the top 1.5% of agents nationwide in 2022, 2025 and again in 2026, a ranking based on verified closed sales. Recognition that keeps showing up across different market cycles tells you he's not a one-year wonder. He's been doing this at a high level for a long time, through rising markets, the 2008 downturn and the post-pandemic rate shock, and the volume shows it.
What Clients Say About Working with Sebastian Frey
Seb has earned dozens of five-star reviews on Google and Zillow, and a few themes come up over and over. The first is communication. Clients consistently say they felt informed rather than pressured, which matters a lot when the decision is this big and the family is involved. The second is his network, since reviewers specifically mention how he connected them with reliable local vendors to get the house ready, which takes a real burden off sellers who don't want to spend weeks finding contractors.
A third theme is out-of-state coordination. For sellers relocating after the sale, Seb identifies qualified agents in their destination area through the Compass agent network, and clients notice it and call it out. Responsiveness comes up a lot too. People mention that he answers questions thoroughly and doesn't disappear between milestones, and for longtime homeowners who haven't been through a transaction in decades, that kind of steady presence makes a real difference.

Local Expertise Across Silicon Valley and Nearby Areas
Silicon Valley covers a wide range of housing, from mid-century ranch homes in Willow Glen and Cambrian to newer townhome developments in Santa Clara and Sunnyvale, plus everything in between. For someone downsizing, the search usually narrows to single-story layouts, low-maintenance yards, and good access to doctors, shopping and family, and those homes don't sit long. Seb's guide to the best Silicon Valley neighborhoods for senior downsizers is a good place to start if you're not sure where you want to land.
The market here moves fast. Highways 101, 280, 85 and 17 shape commute patterns and property values, and buyers stay focused on access to tech employers, amenities and established school districts. For a seller who's been in the same home for decades, the question of whether to stay in the same neighborhood or look at surrounding communities is a real one, and the answer isn't always obvious. Seb tracks inventory and pricing across the area (you can see city-level numbers on his San Jose home prices and Los Gatos home prices pages), uses recent sales to price outgoing homes accurately, and structures offers that protect his clients' timelines so the two sides of the move don't get out of sync.
2026 Market Snapshot for Santa Clara County
According to Redfin's August 2026 data for Santa Clara County, which covers all home types, the local market looked like this:
- Median sale price: about $1.53 million, down 2.2% year over year
- Median days on market: 19 days, two fewer than a year earlier
- Homes sold: 965, down 4.5% year over year
- Average sale-to-list ratio: 102%
- Homes sold above list price: 49.7%
Single-family homes on their own run higher. The Santa Clara County Association of REALTORS® reported an August 2026 median single-family price of $1,850,000, down 1.6% from a year earlier, with homes averaging 25 days on market. Taken together, those numbers tell you what you need to know. Homes priced right are still selling quickly and often above asking, even with prices flattening a bit. For buyers, that means having financing lined up and being ready to move, because hesitation is expensive here. For sellers, accurate pricing isn't optional, it's the whole strategy.

What does a downsizing real estate agent do differently?
A downsizing agent focuses on the logistics of moving out of a long-held home, not just the sale itself. Seb Frey works mainly with clients between 60 and 80, helping them evaluate their equity, prepare an older home for sale, understand the tax picture, and coordinate the purchase of a smaller replacement property so both sides of the move line up.
Should I sell my current home before buying a smaller one in Silicon Valley?
It depends on your financial flexibility. Selling first gives you an exact budget for the next purchase and removes the risk of carrying two homes, while buying first means you only move once. Seb helps sellers compare both options and often uses a rent-back or bridge financing to close the gap so you're never without a place to live.
Can I keep my low property taxes if I downsize?
Often, yes. Under Prop 19, California homeowners 55 and older can transfer their property tax base to a replacement home anywhere in the state up to three times, as long as the replacement is purchased within two years of selling. If the new home costs more than the old one sold for, part of the difference is added to the transferred base. You can estimate the savings with Seb's Prop 19 calculator, and you should confirm the details with your county assessor or tax advisor.
Will I owe capital gains tax when I sell my longtime Silicon Valley home?
Possibly. If you've owned and lived in the home for at least two of the last five years, you can exclude up to $250,000 of gain, or $500,000 for married couples filing jointly. Many longtime Silicon Valley owners have gains well above that, so it's worth meeting with a CPA before you list. Surviving spouses may also have a stepped-up basis on community property, which can make a big difference.
Do downsizing agents in Silicon Valley help with preparing the house?
Good ones do. Seb maintains a network of local contractors, stagers, cleaners and senior move managers and connects clients with the right people to handle repairs and updates before listing. Eligible sellers can also use Compass's Market Ready Concierge program, which covers up to $75,000 in pre-sale work with nothing due until closing.
What happens if my house sells before I find a replacement home?
You may need temporary housing, or you can negotiate a rent-back with the buyer that lets you stay in the home for a set period after closing. Seb works to align closing dates whenever possible and builds rent-back terms into the deal when they're needed.
How does Sebastian Frey help clients moving out of state?
Seb handles the sale of the local home while coordinating with professionals in the destination area. Through the Compass agent network he finds qualified agents in other states, and clients note that this gives them continuous representation through the whole relocation. Keep in mind that Prop 19 tax base transfers only apply to replacement homes inside California.
