Market Notes, Issue #22: What a Bedroom Costs | Level Up Market Intel with Michael Bilger

Type a number into the bedroom filter and you have already made most of a decision. A couple picks two. A family picks three. A family planning to stay a long while picks four. Nobody says out loud what those choices cost, so that is what I want on the table here, rung by rung. And then the part that matters more to your money. Strip size out of it, put two homes of the same square footage side by side, and does the extra bedroom buy you anything?

Across 4,804 closed sales in the last 12 months, the arithmetic is plain. A third bedroom in a house runs about $469,000 and a fourth about $831,000. Almost none of that is the room itself. You are buying the floor area it happens to sit in.

How much does a 2, 3 or 4 bedroom house cost in San Francisco?

Take the 12 months ending September 1, 2026. The median single-family house with two bedrooms closed at $1,400,000. Three bedrooms: $1,869,000. Four: $2,700,000. Those medians rest on 485, 894 and 607 sales, deep enough to lean on. Five bedrooms and up is a mixed group, Excelsior houses with rooms added downstairs sitting in the same bucket as Pacific Heights mansions, and it closed at a median near $3,305,000 on 264 sales.

Each rung costs more than the one below it. Moving from two bedrooms to three costs $469,000, or 33.5%. Moving from three to four costs $831,000, or 44.5%, close to twice the dollars of the step before it. The spacing widens the higher you stand.

The bedroom ladder: median sold price by bedroom count Closed sales September 2, 2025 through September 1, 2026. The step between rungs is computed from the exact medians before rounding. Houses with five or more bedrooms and condos with four are shown for scale. San Francisco MLS via POTM Command.

How much does a 1, 2 or 3 bedroom condo cost?

Condos and townhouses start their climb from a much lower first rung. One bedroom: $730,000 on 823 sales. Two: $1,350,000 on 1,089. Three: $1,900,000 on 507. Four reached $2,525,000, but only 74 sales sit behind it, so hold that one loosely. The heavy step here is the second bedroom, worth $620,000 and an 85% climb, and that is largely a function of how low the one-bedroom rung sits. After that the increments settle down: $550,000 for the third, roughly $625,000 for the fourth.

Downtown draws the same pattern in heavier lines. Take the corridor neighborhoods and the second bedroom becomes a $647,500 step. The median one-bedroom there closed at $702,500 against $1,350,000 for the median two-bedroom, on 338 and 329 sales. The neighborhoods behind that count: SoMa, South Beach, Mission Bay, Yerba Buena, Van Ness/Civic Center.

Is the price the bedroom, or is it the square feet?

Now the number that rearranges everything above it. Price per square foot barely moves across the rungs. Two-bedroom houses: $1,132 per square foot. Three-bedroom: $1,125. Four-bedroom: $1,138. One price, three rungs. What separates them is floor area, a median 1,214 square feet, then 1,710, then 2,412. So a bedroom is not what is being bought here. Roughly $1,130 a foot for a larger house is what is being bought, and the bedroom count is the shorthand a listing uses to say how large.

The team ran it the other way around, holding size still. Within one band of square footage, what price did a single extra bedroom actually fetch?

Same square feet, one more bedroom Median sold price by bedroom count inside each size band, houses above and condos below, same 12 months. A slice under 10 sales is not plotted. The reading at right is the step from the middle bedroom count to the next one up, except where noted. San Francisco MLS via POTM Command.

Houses give an answer that stings if you have ever framed a wall to create a bedroom. Between 1,000 and 1,400 square feet, two bedrooms and three fetched the same money, $1,370,000 and $1,369,000. Above 1,400 square feet the three-bedroom is where the market is happiest, and a four-bedroom of that same size sold for less. At 1,400 to 1,800 square feet that is $1,610,000 against $1,759,000. At 1,800 to 2,200 it is $2,050,000 against $2,160,000. At 2,200 to 2,800 it is $2,850,000 against $3,000,000. Behind those bands sit 59, 137 and 197 four-bedroom sales. Put four bedrooms inside 1,600 square feet and you have four small rooms. Dividing the same dinner onto more plates does not make more dinner, and buyers pay for rooms they can live in.

Condos flip the rule, though only at the first step. Even with size held still, a second bedroom earns its price: +$142,500 in the 700 to 1,000 square foot band and +$370,000 from 1,000 to 1,300, on 372 and 178 sales in the smaller band, 82 and 437 in the larger. Buyers treat a 1,100 square foot one-bedroom and a 1,100 square foot two-bedroom as two different products, and far more of them want the second one. A third bedroom in a condo is another matter. It buys nothing between 1,000 and 1,300 square feet, $42,500 between 1,300 and 1,700, and starts paying its way, about $152,500, only above 1,700.

Where is the third bedroom cheapest, and where does it cost the most?

Where you look moves this number more than anything else in the issue. The cheapest third bedroom in the city is $88,000 in District 10, Bayview and the Excelsior, where the stock is uniform and the added room is usually a basement finished off. The dearest is $579,000 in District 5, Noe, the Castro and the Haight, with District 7 somewhere near $1.5 million, though the two-bedroom house is so scarce there that the step is not rated. District 2, the Sunset and Parkside with it, sits close to the flat end: $251,000 for the third bedroom, $343,000 for the fourth, on 104, 187 and 96 sales. District 1, the Richmond, charges more than twice that at both rungs. Every cell, with its sample size and reliability label, is in By the numbers.

Here are the condo ladders, one per district, over the identical window and with counts shown. Anything built on fewer than ten sales goes unrated. Where a step rests on a rung of under twenty, we call it Directional:

Which bedroom count sells fastest?

Bedroom count buys you nothing on speed. Whether a house had two, three or four, the median sale took 12 days, and between 82% and 87% of each group finished over asking. The exception sits at the top: five bedrooms and up ran 14 days and 63.6% over asking, because that end of the market bargains rather than sprints.

Condos are different, and the split happens at the second bedroom. One-bedrooms took a median 29 days, with 35.1% closing over asking. Two-bedrooms took 15 days, 52.0% over. Three-bedrooms, 13 days and 64.7%. So the one-bedroom is the softest, slowest thing in this issue, which is the second bedroom's premium looked at from the other end.

The rungs pulled apart this year

Condos first, since they are the quieter half of this. One-bedrooms gained 3.2%, to $730,000, and two-bedrooms 8.1%, to $1,350,000. Houses did more, and they did more at the top. A year ago the two-bedroom median stood at $1,300,000; today it is $1,400,000, a gain of 7.7%. The three-bedroom went from roughly $1,611,000 to $1,869,000, up 16.0%. The four-bedroom went from $2,247,000 to $2,700,000, up 20.2%. Bigger house, bigger gain. That is the house-market heat tracked here since Issue #13, and it now reads as daylight widening between the rungs.

Putting this to work

For buyers, I would start from square footage and neighborhood, look hard at the floor plan, and treat a bedroom count as a filter rather than the thing your money is buying. A 1,700 square foot three-bedroom laid out well beats a chopped up 1,700 square foot four-bedroom on price, on light and on resale, and the closings already show it. Condos are the one place that advice reverses. If a two-bedroom is within reach at all, that second bedroom holds its value and moves in half the time, which makes it worth stretching for.

Selling a house? Resist the urge to frame a wall and call it a bedroom. What you get is a four-bedroom that trades like a three-bedroom of the same size, minus the dining room you gave up. That money does more for you inside the rooms already there. Selling a one-bedroom condo is a different job: price for a market that takes 29 days and a buyer pool that mostly does not bid above asking, and lead with square footage and outdoor space, because those are the terms the second-bedroom buyers will judge you on.

Whatever you are doing, price your own bedroom count on your own blocks before you set a budget or a list price. A citywide ladder is a map. The block is the territory, and the two are never quite the same thing.

Frequently asked questions

How much does a 3 bedroom house cost in San Francisco?

$1,869,000 is the citywide figure, drawn from 894 closings on three-bedroom single-family houses in the 12 months ending September 1, 2026, at a median size of 1,710 square feet. District 10, meaning Bayview and the Excelsior, sits at $1,123,000. District 7, the Marina and Pacific Heights, sits at $4,215,000. One median hides that entire spread.

How much more does a 4 bedroom house cost than a 3 bedroom?

Roughly $831,000 more at the citywide median, $2,700,000 against $1,869,000, a step of 44%. Nearly all of that is floor area rather than the room itself: the median four-bedroom measures 2,412 square feet next to 1,710 for the median three-bedroom. Hold size constant and the order reverses, with four-bedroom houses selling under three-bedrooms in every band above 1,400 square feet.

How much does a 2 bedroom condo cost in San Francisco?

Over the 12 months ending September 1, 2026, the median condo or townhouse with two bedrooms closed at $1,350,000, on 1,089 sales and a median 1,232 square feet. A one-bedroom came in at $730,000 and a three-bedroom at $1,900,000.

Does adding a bedroom increase home value in San Francisco?

Only when the bedroom brings square footage with it, or fixes a bad floor plan. Houses at two, three and four bedrooms all traded near $1,130 per square foot, and a fourth bedroom cut out of existing space sold $110,000 to $150,000 under a three-bedroom of the same size. Condos are the exception, and only at the second bedroom, which added $142,500 to $370,000 even at matched size; a third added little below about 1,700 square feet.

Which sells faster, a 1 bedroom or a 2 bedroom condo?

Two bedrooms. Speed is where the one-bedroom condo shows its weakness: a median 29 days on market across the last 12 months, and just 35% of them beating asking. The two-bedroom cleared in 15 days with 52% beating asking. Nothing like that split appears in houses, where two, three and four bedrooms all ran a median 12 days.

AI Corridor Scoreboard

Condos beside the new AI offices are the softest thing in San Francisco right now. One reading here every issue, so the turn shows up as it arrives rather than long afterward.

Issue	Date	Reading	Call
#22 (this issue)	Sep 2, 2026	The steepest second bedroom in the city. Corridor one-bedrooms sold at a median $702,500 and two-bedrooms at $1,350,000 over the last 12 months, a $647,500 step on 338 and 329 sales, with both rungs still at or just under asking (99.7% and 99.6%) in 34 and 23 median days.	The corridor still negotiates, and the one-bedroom negotiates longest.
#21	Aug 30, 2026	Still the calm end of the map. South Beach at asking on 167 sales with 29.9% over; SoMa, Mission Bay and Van Ness / Civic Center at asking; Yerba Buena 1.7% below. Meanwhile 56.6% of condos citywide now clear asking, up from 36.4% a year ago.	The negotiator's end of the market, with the floor rising underneath it.

Issue	Date	Reading	Call
#20	Aug 25, 2026	Two markets, one label. Corridor towers still at or below asking over the past six months (South Beach at asking on 168 sales, Yerba Buena -2.2%) while low-dues flats citywide cleared 10%+ over in 59.9% of sales.	Check the dues before you plan the offer.
#19	Aug 18, 2026	Where cash buys the most and shouts the least. Corridor condos ran 41.7% cash in the past 12 months, the heaviest concentration this series tracks, yet cash and financed closed at the same price, 99.2% versus 99.3% of asking. Cash's whole edge here is the clock: 20 median days on market against 39 financed.	Financed buyers give up nothing on price here; they pay in patience.
#17	Aug 9, 2026	Zero, which is the cleanest reading this scoreboard has produced. Across 368 corridor condo closings so far in 2026, not one sold $1,000,000 over asking, and the typical one closed slightly under asking: South Beach 0.7% below on 183 sales, South of Market 1.0% below on 79, Yerba Buena 2.4% below on 53, Mission Bay exactly at asking on 53. In an issue about where the overbidding is, the corridor is where it is not.	Buyer opening holds, and this issue measures exactly how wide it is.
#16	Aug 6, 2026	Flat in every window, which this issue argues is the whole point. South Beach condos read 100.0% of asking at 30, 90 and 180 days and 99.0% over the trailing year. South of Market reads 99.4, 99.8, 99.6 and 99.0. Four windows, one answer. Every house lane in this issue moved when the window moved; the corridor did not, and a segment that reads the same no matter how you slice it is a segment that is not turning.	Buyer opening holds, and now it is measured four ways instead of one.
#15	Aug 2, 2026	Unchanged at the bottom of the same ladder. This issue extended the over-asking gradient into small multifamily, and the corridor still anchors the low end: right at asking, while two-unit buildings cleared 11.7% over and houses 23.8%. The ordering is by how much a property lives like a house, and a corridor tower is the furthest thing from one.	Buyer opening holds, and this issue explains why it persists.
#14	Jul 29, 2026	Read on supply this time, not price. Citywide condo and townhome months of supply fell from 3.9 to 1.7 in a year and active listings from 772 to 480, so even the calmest lane in the city now offers less to choose from. This issue did not re-measure corridor pricing.	Buyer opening holds on price; the shelf behind it is thinner.
#13	Jul 25, 2026	Graduated to the essay. Back at asking for the first time since 2022, after three springs about 1% below it, and the clock changed: median market time fell from 38 days to 19 and the share selling over asking roughly doubled, from the low twenties to the mid forties. Price at par, speed doubled.	Negotiating room intact; the window now narrows in speed, not price.
#12	Jul 21, 2026	Still the calm corner, and it proves the point. District 9 condos, SoMa, Mission Bay, and South Beach, sold right at list, about 100%, with only 31% over asking on 836 sales, while mid-priced houses cleared 123 to 127% of list. Condos rarely get listed low to start a war, so the overbid never appears.	Buyer leverage holds where the list-low tactic is not used.
#11	Jul 17, 2026	Unmoved by the house story. While overbidding ran one tier below the trophy core, the corridor and condo core cleared near asking, and the two flat lanes the field named as spillover candidates, Hayes Valley and Lower Pacific Heights, stayed calm in closed data.	Still the clearest buyer opening in the city.
#10	Jul 14, 2026	Still soft while the headline is elsewhere. June's million-over-asking story is a west-side and central house market, not the AI-corridor towers. District 9 condos, SoMa, Mission Bay and South Beach, ran about 10% below last year even as volume climbed. Activity returns to the corridor; pricing has not.	Still the clearest buyer opening in the city.
#09	Jul 10, 2026	Still the soft floor at the halfway mark. District 9 condos, SoMa, Mission Bay, and South Beach, sold near 100% of list with only about 36% over asking on roughly 290 sales this year, while citywide houses ran near 121% of list. The widest lane in the city stays open.	Clearest buyer opportunity holds into the second half.
#08	Jul 5, 2026	Still the soft floor even as the top books records. District 9 condos, SoMa, Mission Bay, and South Beach, sold near 100% of list with heavy cash and light competition, while $5M+ houses set a decade volume record at about 112% of list on roughly 64% cash. Cash without a crowd here.	Buyer opportunity intact where the crowds are not.
#06	Jun 25, 2026	Still the calm corner while the house middle runs hot. District 9 condos, SoMa, Mission Bay, and South Beach, sold right at list, about 100%, with only 35% over asking on 300 sales, against the $1.5M to $3M house band at 122 to 125% of list.	Buyer opportunity holds where the bidding wars are not.
#05	Jun 21, 2026	Cash, not heat. Corridor condos carry heavier cash than the citywide condo average, about 42% versus 37%, yet still sell near 98.7% of list with only about 20% over asking versus 45% citywide. Cash concentrates here; competition does not.	Negotiating room for financed buyers.
#04	Jun 17, 2026	Still the soft floor while houses raced ahead. Corridor near 98 to 99% of list versus 103.8% citywide and about 123% for single-family in the last 30 days.	Buyer opportunity holds; the gap to houses only widened.
#03	Jun 13, 2026	Still the bottom of the overbid table. Corridor sale-to-list at about 98 to 99% versus 103.6% citywide, trailing year.	Opportunity intact for negotiators.
#02	Jun 10, 2026	Turning at the edges. Citywide condos hit 101.4% of list in May; inventory fell to 584 from 905. The corridor towers remain the soft end.	Window narrowing, not closed.
#01	Jun 7, 2026	Soft. Only 37 to 43% of SoMa, Mission Bay, and downtown condos sold over asking.	Clearest buyer opportunity in the city.

Takeaways

The last 12 months in exact medians. Condos run $730,000, $1,350,000 and $1,900,000 as the bedrooms go one, two, three. Houses run $1,400,000, $1,869,000, $2,700,000 and $3,305,000 from two bedrooms up to five or more. As steps, a house's third bedroom is about $469,000 and its fourth about $831,000, close to twice as much.
Price per foot barely moves: $1,132, $1,125 and $1,138 at two, three and four bedrooms, call it $1,130 across the board. What does move is size, a median 1,214 square feet, then 1,710, then 2,412. Size is the ladder. The bedroom is the label on the rung.
Fix the size and a fourth bedroom becomes a discount. At 1,400 to 1,800 square feet it is $1.61M against $1.76M for a three-bedroom; at 2,200 to 2,800 it is $2.85M against $3.00M. From 1,400 square feet up, a three-bedroom of equal size outsold it in every band.
Condos break that rule once, at the second bedroom, which earns its keep with size held constant: +$142,500 across 700 to 1,000 square feet, +$370,000 across 1,000 to 1,300. Go up to a third and nothing arrives until roughly 1,700 square feet. Speed says the same thing: a one-bedroom sits 29 median days to a two-bedroom's 15, and 35% of them clear asking against 52%.
District spread on the third bedroom: +$88,000 in District 10, +$579,000 in District 5, roughly +$1.5M in District 7. The rungs also pulled apart this year, with two-bedroom houses up 7.7% year over year, three-bedrooms up 16.0% and four-bedrooms up 20.2%. Bigger home, bigger gain.

Methodology and sources

Source: POTM Command, governed MLS analytics, September 1, 2026 data, 62,689 governed closed sales since 2016. This issue reads closed sales from September 2, 2025 through September 1, 2026: 2,303 single-family houses and 2,501 condominiums and townhouses, every one with a reported bedroom count. Year-over-year figures use the identical window one year earlier. Every figure is an exact median, never an average; the step between rungs is computed from the exact medians before rounding. Bedroom counts are as reported to the MLS; a legal bedroom, a den and a converted garage room are whatever the listing agent called them, and square footage is as reported, missing on about 6% of sales, which the size bands exclude. Price per square foot is the median of each sale's own ratio. District medians at 20 or more sales are Strong, 10 to 19 Directional, under 10 not rated; the tables say which.
