South Dakota Home Prices in 2026: FHFA Index Data, 1/5/10-Year Trends
South Dakota’s housing market has posted steady, compounding gains over the past decade, and 2026 data confirms that appreciation has not stalled. According to the Federal Housing Finance Agency (FHFA) all-transactions House Price Index retrieved from FRED (fred.stlouisfed.org) on 2026-07-18, the South Dakota index reached 642.33 in Q1 2026 — up 4.2% from a year earlier and a remarkable 91.8% above where it stood ten years ago. For buyers weighing a move to the Mount Rushmore State, understanding the pace and trajectory of these gains is essential context.
1-Year, 5-Year, and 10-Year Change at a Glance
The table below summarizes the index at three historical benchmarks compared to the Q1 2026 reading of 642.33. These figures come directly from FRED series SDSTHPI.
| Lookback Period | Date | Index Value | Absolute Change | Percent Change |
|---|---|---|---|---|
| 1 Year Ago | 2025-01-01 | 616.25 | +26.08 | +4.2% |
| 5 Years Ago | 2021-01-01 | 426.75 | +215.58 | +50.5% |
| 10 Years Ago | 2016-01-01 | 334.94 | +307.39 | +91.8% |
The 10-year gain of 91.8% is the headline figure. It means a home that tracked the index precisely would have nearly doubled in price-index value over the past decade. The 5-year gain of 50.5% captures most of that surge, reflecting the pandemic-era boom that drove prices sharply higher across much of the country from 2021 onward. The most recent 1-year gain of 4.2% is moderate by comparison — suggesting the market has cooled from its peak frenzy but has not reversed.
Recent Quarterly Trend
Looking at the eight most recent quarterly data points provides a clearer view of the current momentum. Values are FHFA index points for South Dakota (FRED series SDSTHPI).
| Quarter | Index Value |
|---|---|
| Q2 2024 (2024-04-01) | 605.17 |
| Q3 2024 (2024-07-01) | 609.68 |
| Q4 2024 (2024-10-01) | 614.51 |
| Q1 2025 (2025-01-01) | 616.25 |
| Q2 2025 (2025-04-01) | 630.42 |
| Q3 2025 (2025-07-01) | 634.10 |
| Q4 2025 (2025-10-01) | 637.06 |
| Q1 2026 (2026-01-01) | 642.33 |
The quarterly progression tells an important story. Through all of 2024, the index moved incrementally — rising just 9.34 points across three quarters from Q2 2024 to Q1 2025. Then came a notable jump: the index gained 14.17 points in a single quarter between Q1 2025 and Q2 2025. Growth moderated again through the rest of 2025 before picking back up with a 5.27-point gain in Q1 2026. Overall, the direction is consistently upward, but the pace is uneven. There is no sign of sustained deceleration that would suggest an imminent price correction based on this data alone.
Is the Trend Accelerating or Cooling?
Compared to the explosive 5-year run that added 50.5% to the index, the current 4.2% annual gain is clearly a cooler environment. The pandemic-driven surge between 2021 and 2023 was exceptional by historical standards, and a normalization toward single-digit annual appreciation is a more sustainable pattern. However, “cooling” does not mean “declining.” Every single quarterly reading in this dataset is higher than the one before it. Buyers hoping to wait for a price dip will find no evidence for that outcome in this data — prices have risen without interruption through the eight quarters shown.
The Q2 2025 acceleration (from 616.25 to 630.42 in one quarter) is worth monitoring. If that represented a renewed upswing rather than a one-quarter anomaly, the annual pace could exceed 4.2% in subsequent readings. For now, the most recent quarters have resumed a more gradual climb, so the dominant signal is modest, steady appreciation.
How South Dakota Compares to National Dynamics
While this article is grounded strictly in the South Dakota FHFA data, a general framing is useful. Nationally, home prices also surged during the 2020–2022 period and have since moderated. South Dakota’s 4.2% one-year gain is broadly consistent with a market that has transitioned from overheated to stable. The state’s relative affordability compared to coastal metros, combined with no state income tax and population growth in cities like Sioux Falls and Rapid City, has sustained demand even as the broader national market cooled. The 91.8% ten-year gain suggests South Dakota has outpaced many traditionally slower Midwest markets over the long run.
About the Data Source
All figures in this article are drawn from FRED series SDSTHPI (South Dakota House Price Index, FHFA), available at fred.stlouisfed.org. Data was retrieved on 2026-07-18. The FHFA all-transactions House Price Index is a repeat-sales index, meaning it tracks price changes on the same properties over time using data from conforming conventional mortgages purchased or securitized by Fannie Mae and Freddie Mac. This makes it a reliable measure of price appreciation trends. Key limitations: it excludes cash transactions and jumbo loans, so it may underrepresent the luxury segment; it is a statewide average and does not capture variation between individual cities or counties within South Dakota; and it is reported quarterly with some lag, so the most recent reading reflects conditions from early 2026, not mid-2026.
What This Means for Buyers
- Prices are not falling. Every quarter in the dataset shows an increase. Buyers waiting for a correction have no data-backed basis for that expectation in South Dakota’s current trend.
- The pace has normalized. A 4.2% annual gain is far more manageable than the 50.5% five-year surge. Buyers who missed the pandemic-era frenzy are entering a calmer market, though not a cheap one — the index is still 91.8% above 2016 levels.
- Each quarter of waiting has a cost. From Q2 2024 to Q1 2026, the index rose from 605.17 to 642.33 — a gain of 37.16 index points, or roughly 6.1%, in under two years. On a $350,000 home, that trajectory would add approximately $21,000 to the purchase price over the same period.
- The Q2 2025 jump warrants attention. A 14-point single-quarter increase broke the slow-and-steady pattern. If that reflects a seasonal or demand surge returning, annual appreciation could re-accelerate beyond the current 4.2% pace.

What is the FHFA House Price Index and does it reflect all South Dakota homes?

It is a solid gauge of broad appreciation trends but excludes cash sales and jumbo loans, and reports a single statewide figure that does not break out individual cities like Sioux Falls or Rapid City separately.
