Peninsula Center homes between 2,000 and 3,000 square feet are trading at a 180-day moving average of $825.89 per square foot — up 4.6% from a year ago, but down 1.7% in the last thirty days alone.

That combination is exactly why I run first and second derivatives on this market instead of just quoting an average. The first derivative — the slope of the curve — just crossed into negative territory in mid-July at -$5.22 per square foot per month. The second derivative — the acceleration — is at -4.35, meaning the market is not just softening, it softened faster this month than last.

But here is the part most headlines will miss: bounded by this submarket’s own ten-year extremes (+29.90% maximum year-over-year appreciation, -17.94% maximum depreciation), the projected path is a shallow drift of roughly -3.1% over 24 months, with velocity crossing back through zero around November 8, 2027. That is a plateau, not a correction.

1. Executive Summary

Across 160 closed sales spanning ten years, the Peninsula Center 2,000–3,000 square foot segment has moved from a 180-day moving average near $500 per square foot in late 2016 to $825.89 as of July 31, 2026 — roughly 65% cumulative appreciation, or about 5.1% compounded annually.

That decade-long arc, however, is not a straight line, and the last three years are the part that matters for anyone transacting now. The moving average peaked in the high-$800s through 2023, then entered a broad, choppy plateau. It stands today +4.61% year over year but -1.68% over the trailing thirty days — and the two-year OLS slope on this series is essentially flat at $0.0015 per day, or +0.07% per year.

The derivatives sharpen the picture considerably. Velocity turned negative on July 13, 2026 and now reads -$5.22 per square foot per month. Acceleration is simultaneously negative at -4.35, confirming the softening is currently gathering rather than shedding force. This is the least favorable of the four possible derivative states — falling and falling faster.

The projection resolves that tension. Modeling current velocity as converging exponentially toward the five-year OLS steady-state slope, and hard-capping the path at this submarket’s own observed year-over-year extremes, produces a trough of $797.03 around November 7, 2027 followed by a shallow recovery to $800.65 by July 31, 2028 — a net -3.06% over 24 months, averaging -$1.05 per square foot per month. In plain terms: a flat-to-mildly-soft two years, not a downturn.

2. Historical Year-Over-Year Extremes (The Projection Governor)

Using only Closed Sale Date and Price Per Square Foot, every point on the 180-day moving average was compared against its value exactly one year earlier (matched with a ±5-day tolerance). Across 3,259 valid year-over-year observations:
LARGEST APPRECIATION
+29.90%
Occurred October 26, 2022
180-day MA rose from $749.16 (Oct 26, 2021) to $973.14 (Oct 26, 2022) — the terminal blow-off of the 2021–2022 low-rate bidding cycle.
LARGEST DEPRECIATION
-17.94%
Occurred May 7, 2019
180-day MA fell from $646.91 (May 7, 2018) to $530.88 (May 7, 2019) — the 2018–2019 rate-shock and inventory-glut trough.
Governing rule applied to this analysis: the 24-month projection is bounded exclusively by these two figures. All boundaries from any prior submarket analysis are disregarded. The projected path never approaches either limit — peak projected year-over-year movement is approximately -3.4%, which sits comfortably inside the -17.94% floor with 14.5 percentage points of headroom.

3. First Derivative — Velocity

The first derivative measures how fast the moving average is changing — the slope of the line, expressed in dollars per square foot per month. Reading the recent record:

Point in Time180-Day MAVelocity ($/sqft/mo)Acceleration
Today (Jul 31, 2026)$825.89-5.22-4.35
1 month ago$839.97+3.24-0.05
3 months ago$838.59+7.51+1.84
6 months ago$818.98+2.24-1.90
12 months ago$789.46-4.78-1.67

Velocity has crossed zero nine times in the past three years — February 2024, June 2024, December 2024, April and May 2025, September 2025, January 2026, and most recently July 13, 2026. That crossing frequency is itself the finding: this is an oscillating plateau, not a trending market. No directional move since 2023 has sustained itself for more than about seven months.

The current reading of -$5.22 per square foot per month is a real negative, but in historical context it is modest. This series has registered velocities as steep as -$53 and as strong as +$60 per square foot per month. Today’s slope sits in the mild ninth of that range.

4. Second Derivative — Acceleration

The second derivative answers whether the momentum is gaining or losing force. Today it reads -4.35 — negative, and it flipped negative on June 30, 2026, roughly two weeks before velocity itself turned. That sequencing is textbook: acceleration leads velocity, and it did so here.

Current State: Quadrant IV — Falling and Losing Force
First derivative negative, second derivative negative. The moving average is declining, and the rate of decline is steepening. Of the four possible derivative combinations, this is the weakest. It is also, historically in this dataset, the shortest-lived — the second derivative has crossed zero nine times in the past three years, with a median run of about three months in any one sign.

The projection assumes this quadrant does not persist. Under exponential convergence, acceleration turns positive almost immediately in the forward path and stays modestly positive throughout — +0.51 at three months, +0.19 at twelve, +0.05 at twenty-four. That is the mathematical signature of a decline that decays rather than compounds.

Derivative-consistency check: the projected first derivative crosses zero on November 8, 2027, one day after the projected moving-average trough of $797.03 on November 7, 2027. Velocity, acceleration, and the price path are mathematically consistent; the zero-crossing is annotated on Chart 2 as the calculus inflection point.

Every point on the path was tested against the ±29.90% / -17.94% governor; zero violations.

PROJECTION GOVERNOR — BOUNDED BY OBSERVED HISTORY
The 24-month projection is hard-capped by the extremes actually observed in this data pool: maximum year-over-year appreciation of +29.90% (October 26, 2022) and maximum year-over-year depreciation of -17.94% (May 7, 2019). The projected path never approaches either boundary — peak projected year-over-year movement is roughly -3.4%. Projection method: exponential convergence of current velocity toward the 5-year OLS steady-state slope ($0.0374/day), integrated forward 730 days.

6. Buyer Advice

Time is on your side — but only about fifteen months of it
Both derivatives are negative right now, which means the next several quarters are the buyer-favorable window in this projection. The path bottoms around November 2027 at $797 per square foot, then turns. If you are buying a 2,400 square foot home, the projected trough is worth roughly $69,000 versus today — real, but not enough to justify sitting out two years and paying rent to capture it.
Negotiate on the second derivative, not the headline
Sellers and their agents will quote the +4.61% year-over-year number, which is accurate. Your counter is that the trailing thirty days show -1.68% and that acceleration went negative before velocity did. Twelve-month trailing sale-to-list ratio in this segment is 0.975, with the bottom quartile closing at 0.955 — there is 2.5 to 4.5 percentage points of documented negotiating room in the recent record.
The dispersion is the opportunity
Within the trailing twelve months, 2,300–2,500 square foot homes closed anywhere from $591 to $1,001 per square foot — a 69% spread inside one size band. That gap is condition, view, and street, not market timing. A dated home at $700 a foot with $150,000 of cosmetic work behind it is a far better use of the next fifteen months than waiting for a 3% market drift.
Watch for the November 2027 crossing, then move decisively
The projected velocity zero-crossing is the signal to stop waiting. Once the first derivative turns positive with the second derivative already positive, both engines point the same direction and the buyer-favorable window closes. Set a calendar reminder for autumn 2027 and re-run the numbers then.

7. Seller Advice

You are selling into a plateau, not a peak — price accordingly
The moving average is 4.6% above a year ago but has given back 1.7% in thirty days, and the projected path does not recover to today’s $825.89 within the 24-month window. Waiting does not help here: the projection says the market is worth 3.1% less in two years than it is this week. If your timeline is flexible, the mathematically favorable answer is to sell sooner rather than later.
Days on market is the variable you control
Median cumulative days on market for the trailing twelve months is 25 days. Homes closing above $950 per square foot in this segment averaged well under 60 days. The homes that sat — Warrior at 111 days, Delacroix at 106 — are the ones that discounted. In a plateau, the first thirty days on market carry nearly all your pricing leverage.
Condition premium is worth more than market timing
City-lights-view homes closed 7.6% above non-view homes over the trailing twelve months, and the top-quartile PPSF threshold is $834 against a median of $791. Golden Arrow closed at $1,001 per square foot on July 31 — 21% above the median — on the strength of remodel, pool, and view. A targeted pre-list investment reliably outruns a 3% two-year market drift.
Price to the recent comps, not to 2023
The 2023 moving-average peak in the high-$800s is three years stale, and this segment has traded sideways since. Anchor to closings from the last six months in your size band and let the buyer’s appraiser find no surprises. Overpricing in a negative-acceleration market produces a price reduction within six weeks, and reduced listings in this pool consistently close below 0.96 of list.

8. Devil’s Advocate — Why This Projection Could Be Wrong

The conclusion above is a mild 24-month decline to a plateau. Here is the honest case for the opposite — that price per square foot in Peninsula Center resumes climbing and the projection understates by a wide margin.

1. Sixteen sales a year is a thin market, and thin markets lie
160 transactions over ten years averages 16 per year, or 1.3 per month. The 180-day moving average is built on a forward-filled daily series, which means a single closing can hold the line for weeks until the next one arrives. The apparent -1.68% thirty-day move rests on a handful of July closings — among them Delacroix at $694 and Lone Valley at $669, both below-median condition. Two different homes closing in that window would have produced a positive slope and inverted the entire derivative reading.
2. The mix is masking price, not measuring it
Price per square foot conflates value with product. Recent quarters have included several larger, dated, non-view properties — Nokomis at 2,784 square feet closed at $625 per foot, Silver Moon at 2,794 closed at $644 — and larger homes structurally carry lower per-foot pricing (the 36-month regression shows -$0.176 per foot for each additional square foot). If the next twelve months skew toward smaller remodeled inventory, the moving average rises even with zero underlying appreciation.
3. The oscillation record argues against any trend call — including mine
Velocity has crossed zero nine times in three years. Every prior negative crossing in that span reversed within roughly seven months. Extrapolating the July 13 crossing forward for fifteen months assumes this one behaves differently from all eight predecessors. The base rate does not support that assumption, and a reversal by early 2027 would be entirely ordinary.
4. The steady-state slope choice is a judgment call, and a conservative one
The projection converges toward the five-year OLS slope of +1.65% per year. The full ten-year OLS slope is $0.1021 per day — +4.51% annually at current levels. Substituting the ten-year slope produces a 24-month terminal value near $855 rather than $800, turning a -3.1% projection into roughly +3.5%. Nothing in the mathematics privileges five years over ten; it is a defensible choice, not a derived one.
5. Supply, not demand, sets the floor on the Peninsula
Peninsula Center is fully built out. Ten years of data show 160 sales in a segment that comprises a substantial share of the area’s housing stock — turnover is structurally low. Any material improvement in financing conditions, or any demand shock into a market that cannot add inventory, resolves upward through price rather than volume. The 2021–2022 episode, which produced the +29.90% governor in this very dataset, is the proof of concept and it is only four years old.

The honest summary: the -3.06% projection is the central estimate of a distribution, not a forecast. A reasonable band around it runs from roughly -8% to +6% at the 24-month mark. What the derivatives establish with confidence is the absence of a strong trend in either direction — and that plateau conclusion is far more robust than the sign of the drift within it.

9. Methodology & Data Integrity

Data pool. 160 closed CRMLS records, MLS Area 175 — Peninsula Center, single-family residences 2,000–3,000 sq ft living area, closing between August 5, 2016 and July 31, 2026. All 160 records used; none excluded. Zero null values in Closed Sale Date or Price Per Square Foot. Zero duplicate MLS identifiers. Dual-pass verification (pandas plus openpyxl with a status-count assertion) passed.

Moving average. Transaction-level PPSF resampled to a daily index, all gaps forward-filled, then a 180-day trailing window applied with a 30-observation minimum. Result: 3,619 moving-average points against 160 transactions, a ratio of 22.6× — confirming forward-fill was applied correctly. Maximum gap in the MA series: one day. Current MA date equals the latest dataset date.

Derivatives. The MA series was smoothed with a Savitzky-Golay filter (91-day window, second-order polynomial, nearest-edge mode) and first and second derivatives taken as trailing 90-day slopes. Trailing rather than centered differencing was chosen deliberately so the most recent reading contains no forward-looking edge artifact.

Regression diagnostics. Full-history OLS slope $0.1021 per day — well inside the $0.50-per-day sparse-series warning threshold. Five-year $0.0374, three-year $0.0149, two-year $0.0015. The steep one-year reading ($0.1468) was rejected as a steady-state candidate for exactly the thin-market reasons set out in the devil’s advocate section.
