The S&P CoreLogic Case-Shiller U.S. National Home Price Index stood at 332.678 in April 2026 on the not-seasonally-adjusted series carried by FRED as CSUSHPINSA. The reading offers a broad view of repeat-sale price movement. It does not mean the typical U.S. home cost $332,678, and it should never be inserted into a property valuation as though it were a comparable sale.
Recent national index observations
| Observation month | Index level |
|---|---|
| April 2026 | 332.678 |
| March 2026 | 330.132 |
| February 2026 | 327.700 |
| January 2026 | 326.695 |
| December 2025 | 327.008 |
The index increased across the latest four observations after sitting at 327.008 in December. Because this is the unadjusted series, some short-run movement may reflect normal seasonality. The limited table is a current snapshot, not evidence by itself of an enduring rate of appreciation.
PortfolioRental checked these observations on July 23, 2026. No missing month was estimated, no seasonal adjustment was added, and no forecast was produced.
How a repeat-sales index works
Case-Shiller uses repeat transactions on the same properties to estimate price change while reducing the composition problem found in simple median-sale figures. Sale pairs are screened and weighted under S&P Dow Jones Indices’ methodology. The national series is a composite of U.S. housing market data and uses January 2000 as 100.
An index value is meaningful relative to another index value from the same series. It is not denominated in dollars. Comparing April with March requires a percentage-change calculation using the two levels; it does not require subtracting the points and calling the result “price growth.” Analysts should also distinguish CSUSHPINSA from the seasonally adjusted companion series and from FHFA’s house price indexes, which have different source data and coverage.
Repeat-sales design solves some problems, not all of them. Renovations or deterioration between sales can affect observed prices. Homes that do not transact do not form sale pairs. Publication arrives with a lag, and recent values may be revised.
Where the index belongs in portfolio work
The index can anchor a national market section, test whether an appreciation assumption looks directionally unusual, or provide context for a portfolio valuation review. It cannot establish the present value of a duplex in one neighborhood. For that task, recent nearby sales, income, lease terms, condition, lot characteristics, renovation history, and appraisal standards matter more.
A useful workflow starts with a candidate’s local comparable set. Record sale date, contract date where available, distance, property type, size, bed/bath count, condition, concessions, and source. Keep raw sale prices beside any adjustments. Then use the national index only as a broad reasonableness reference, explaining why the local market may differ.
The existing-home sales statistics add transaction-volume context without implying causation. More housing datasets are organized in the research library, and financial reporting and analysis can support consistent portfolio records.
A valuation example
Assume an older rental last sold several years ago and an analyst is tempted to multiply that sale price by the change in the national index. The result may be a screening estimate, but it is not a defensible appraisal. The property may have changed condition, the neighborhood may have diverged from the nation, and the prior transfer may not have been arm’s length.
A better file labels the indexed figure as a sensitivity, obtains current local comparables, verifies improvements and deferred maintenance, and reconciles the indicated values. If the index and local evidence disagree, the memo should identify the likely geography, timing, or property-quality explanation rather than average incompatible estimates.
Data controls and limitations
For reproducibility, retain the exact code CSUSHPINSA, the base period, adjustment status, observation month, download date, and source URL. Save the source file used for every material committee packet. Do not silently swap in the adjusted series because its latest movement appears smoother.
The largest misuse risks are straightforward: calling the index a dollar price, treating national change as local appreciation, mixing adjusted and unadjusted levels, or confusing a repeat-sales index with a median. A median can change when the mix of sold homes changes; a repeat-sales measure follows price changes among qualifying paired transactions. Both can be useful, but they answer different questions.
Verification checklist
- Confirm the series is CSUSHPINSA, not its adjusted companion.
- Record that January 2000 equals 100.
- Match each value to its observation month.
- Check S&P DJI release materials and the FRED display.
- Preserve revisions to recent history.
- Never label an index point as dollars.
- Compare only compatible series and adjustment bases.
- Build a current, property-specific comparable set.
- Document renovations, condition, and non-arm’s-length sales.
- Date every conclusion and schedule a refresh.
Frequently asked questions
Is 332.678 the average U.S. home price?
No. It is an index level relative to a January 2000 base of 100, not a dollar-denominated average or median.
Is this series seasonally adjusted?
CSUSHPINSA is not seasonally adjusted. Analysts seeking the adjusted companion must use its separate series and clearly label the change.
Can the index update an old purchase price?
It can support a rough sensitivity, but it cannot replace local comparables, an appraisal, or a condition review. Geography and property changes can create large differences.
Why does Case-Shiller differ from FHFA’s index?
The providers use different transaction sources, eligibility rules, weighting, geography, and methodology. Differences do not automatically indicate an error.
Can index growth be used as a rent-growth assumption?
No. Home values and rents are distinct measures. Rent assumptions require rental-market evidence with matching location and property type.
