From My Desk
Happy September!
This month so far has been spectacular in many ways: I've been quietly working on www.claudiainsider.com, developing more resources for my buyer clients to give them something to lean on when sitting down face-to-face or on the phone isn't possible (as much as I love educating, I also know you've got busy lives!), and preparing 331 Swallowtail Ct. Ah, also: I celebrated my birthday the other day!
This month, one of the biggest things I've learned is that preparing a listing is much like making beef rendang (my birthday meal). The most demanding parts are in the prep work: organization, staging (vendors coordinated in a very specific order, marketing rolling out piece by piece), allowing everything to slowly and surely meld together, and readjusting and refining at the end. Same as rendang: you activate the spices, blend, then slowly integrate everything else into the big pot. It's been wonderful seeing the development of this unit. From choosing the countertops, backsplash, carpets, and finishes to seeing them installed, I'm so excited to present 331 Swallowtail to the market next month!

This Month's Numbers
SF's Two-Track Market
Single-family homes and condos are telling two very different stories this fall — and the gap is getting interesting for buyers.
Let's start with the headline: the median single-family home in San Francisco sold for $2.014 million in August, with properties spending a median of just 13 days on market. That is still an extraordinarily competitive segment. Multiple offers are common in Pacific Heights, Noe Valley, and the Sunset — particularly for anything under $2.5M that shows well.
Inventory for single-family homes sits at 0.8 months of supply. For context, a balanced market is 4–6 months. We're nowhere close.
The condo side of the market is where the real shift is happening. A year ago, condos in SF were languishing — 51 median days on market last August, with buyers dictating terms. Fast forward to today: that number has dropped to 19 days, and the median price is $1.22 million. Still softer than single-family, but the trend is unmistakable.
What's driving the condo compression? A few things. Return-to-office mandates from major employers have reignited demand for urban, walkable units. New construction has slowed dramatically. And buyers who got priced out of the single-family market are finding real value in well-located condos — especially in Hayes Valley, the Marina, and Dogpatch.

| Address | Sale Price | Over Asking | DOM |
|---|---|---|---|
| 2847 Pacific Ave, Pacific Heights | $3,850,000 | +$350K | 7 |
| 1156 Sanchez St, Noe Valley | $2,475,000 | +$175K | 9 |
| 1044 Green St, Russian Hill | $3,200,000 | +$200K | 11 |
| 386 Sea Cliff Ave, Sea Cliff | $4,125,000 | +$425K | 5 |
| 825 Carl St, Cole Valley | $2,190,000 | +$190K | 12 |
The takeaway? If you're a condo buyer, you still have more negotiating room than in the single-family space — but the window is narrowing month by month. And if you're a condo seller who's been on the fence, the market is working in your favor for the first time in two years.
The Charts
What the Data Says
SF Median Sale Price — Single-Family Homes
What it means: SFH prices surged through spring, peaking in May at $2.15M before pulling back modestly. The August reading of $2.014M suggests the seasonal cooldown is gentle — prices are still 30% above last September.
SF Median Sale Price — Condos
What it means: Condo prices peaked in April–May at $1.35M before cooling. At $1.22M, condos are still 11% above last October's trough. The recovery is real but has plateaued — good news if you're still shopping.
Days on Market — SFH vs. Condos
What it means: The DOM gap between SFH and condos has collapsed — from 29 days apart last September to just 6 days now. Condo demand is catching up fast, and sellers who price correctly are seeing offers within three weeks.
Months of Supply — SFH vs. Condos
What it means: SFH supply is firmly in seller's market territory at 0.8 months. Condo supply has been halved from 3.5 months last October to 1.8 now — still more balanced, but no longer a buyer's free-for-all.
Active Inventory — SFH vs. Condos
What it means: Condos still outnumber SFH listings 2-to-1. But the gap peaked in January (440 vs. 230) and has narrowed. Condo inventory is being absorbed faster than it's being replenished — a structural tailwind for prices.
30-Year Fixed Mortgage Rate
What it means: Rates have climbed steadily from 6.15% last October to 6.95% today, despite the Fed holding at 3.75–4%. The bond market is pricing in persistent inflation. Don't wait for 5% — it's not coming soon.

National Backdrop
The Bigger Picture
SF doesn't exist in a vacuum. Here's what's shaping the national housing landscape this month.
Mortgage Rates
The 30-year fixed sits at 6.95%, inching toward 7% for the first time since late 2023. The Fed funds rate is at 3.75–4.00%, but the long end of the curve is being driven by inflation expectations and treasury supply. Translation: don't expect meaningful rate relief until the Fed signals it's done tightening — and markets believe it.
Inflation & Energy
CPI came in at 3.4% year-over-year in August — stubbornly above the Fed's 2% target. Oil at $107/barrel isn't helping, and shelter costs (which lag real-time rents by ~12 months) are still pulling the index up. The good news? Core services inflation is decelerating. The bad news? Not fast enough for rate cuts.
Housing Equity
The average U.S. homeowner has $310,500 in equity — a record. In California, that number jumps to roughly $627,000. This is why you're not seeing a wave of distressed sales: homeowners have massive equity cushions and most are locked into sub-5% mortgages. Voluntary sellers only, which keeps supply tight.
The Market Split
Nationally, starter homes are down 5.4% year-over-year as affordability constraints bite. Meanwhile, luxury homes (top 5% by price) are up 6.2%. The bifurcation is real: cash-rich buyers are competing fiercely at the top, while rate-sensitive first-time buyers are pulling back. SF mirrors this pattern almost exactly.
The Money Lesson
The New Condo Reserve Rule (And Why You Should Care)
If you're thinking about buying a condo in the next year, there's a rule change coming that could affect your financing — and almost nobody is talking about it yet.
Starting January 4, 2027, Fannie Mae will require that condo associations hold reserves equal to at least 15% of their annual operating budget. This is a direct response to the Surfside condo collapse in Florida and a broader push for safer, better-maintained buildings. And it's going to ripple through the SF condo market in ways that matter.
What does this actually mean?
Right now, many condo HOAs — especially older buildings in SF — operate with minimal reserves. They collect enough in dues to cover day-to-day expenses, but there's not much set aside for big-ticket repairs (think: roof replacement, elevator modernization, seismic retrofitting). Under the new rule, if your building doesn't meet the 15% threshold, conventional Fannie Mae–backed loans won't be available to buyers in that building.
That's a big deal. Without conventional financing, buyers would need jumbo loans, portfolio loans, or cash — all of which are more expensive or harder to qualify for. And if buyers have fewer financing options, it puts downward pressure on prices in non-compliant buildings.
What should you ask your HOA?
If you're buying (or own) a condo, here are the three questions to ask right now:
1. What percentage of the annual budget is currently in reserves? If it's under 15%, find out if there's a plan to get there by January 2027.
2. Is a special assessment likely? Some HOAs will raise dues gradually; others will levy a one-time special assessment to bulk up reserves. Know which path your building is on.
3. Has the building had a reserve study in the last 3 years? A professional reserve study identifies what major repairs are coming and how much they'll cost. It's the foundation of responsible reserve planning.
How this affects older buildings
San Francisco has a lot of beautiful, older condo buildings — think 1920s Marina co-ops converted to condos, or 1960s–70s mid-rises in Pacific Heights and Russian Hill. These buildings tend to have higher deferred maintenance and lower reserves. If they don't get compliant before January 2027, they could see a meaningful impact on resale values.
The flip side? Buildings that are well-reserved and well-maintained will become even more attractive by comparison. It's a quality filter — and I think that's ultimately healthy for the market.
This isn't legal or financial advice — just context to help you ask the right questions. Talk to your lender and your agent (hi, that's me) if you want to dig into how this affects a specific building.
Insider Spot
Frank Grizzly's
I have a very specific gripe with Cantonese roast duck buns: too much bao, never enough duck. Frank Grizzly's in Bayview fixed that problem with a taco, and I haven't stopped thinking about it. Hoisin, greens, plenty of duck, diced mangos on top for this perfect hit of acidity. The fish taco is not messing around either, and a local tipped me off to the shrimp — that's first on the list next visit.
What makes this spot an Insider pick is the energy. The owners know their regulars by name, face, and story. It's counter-service with that neighborhood feel where everyone just belongs — Bayview in a taco shop. Fair warning on portions: I can normally tank 5 tacos and was full after 3. You've been warned.
