Indiana's housing market cooled through late summer 2026 without losing its price gains. The Indiana Association of REALTORS (IAR) reports a statewide median sale price of $282,395 in August 2026, up 3% year over year, while closed sales fell 6% and average daily inventory rose 12% to 20,416 homes. Prices are still rising, but more slowly.
For property owners, the timing matters more than the headline. The sales happening right now are the raw material for your January 1, 2027 assessment (taxes payable 2028). The assessment you are being billed on next spring, the January 1, 2026 assessment, was built from calendar-2025 sales.
Indiana Housing Market Data Through August 2026
IAR's August 2026 Monthly Market Report, published September 9:
| Metric (Indiana, August 2026) | Value | Year over year |
|---|---|---|
| Median sale price | $282,395 | +3% |
| Closed sales | 7,713 | -6% |
| New pending contracts | 8,585 | -4% |
| Average daily inventory | 20,416 | +12% |
| Months of inventory | 2.9 | +10% |
| Days from listing to pending | 24 | +14% |
The summer peak came earlier. IAR's mid-year report (July 8) put the first-half median at $275,000, up 5%, and said June's $290,000 median was an all-time state-level monthly high. Its summer wrap-up (September 16) reports a June-August median of $285,000 (+4%), with the monthly median running 3% to 5% above 2025 every month since January. Pending sales peaked in April and May, then fell about 5% a month as mortgage rates climbed to an average of nearly 6.7% in August.
An independent measure points the same way. The FHFA's Q2 2026 House Price Index (released August 25) shows national prices up 2.1%, with the East North Central division, which includes Indiana, leading all divisions at 4.5%. Indiana's purchase-only index in FHFA's state dataset rose about 3.5% from Q2 2025 to Q2 2026.

Regional Differences Across Indiana
IAR's Market Heat Index (June data, from the mid-year report) blends days on market, sale-to-list ratio, and how fast listings go under contract:
- Northern Indiana runs hottest. Michigan City (60), Fort Wayne (49), South Bend (44), and Elkhart (41) topped the index.
- Central Indiana is warm but uneven. Hamilton County scored 58, with buyers paying 98.6% of asking after 12 days. Brown County sat at -18 with a 65-day market time.
- College towns cooled. Lafayette-West Lafayette fell from 31 to -9. Bloomington scored -62: only 29 of every 100 new listings found a buyer, homes sat nearly 58 days, and they sold at 94.7% of list.
Price tiers split too: summer pending sales under $250,000 fell 6% while contracts above $250,000 rose 4%. For how regional trends have already shown up in assessed values, see Indiana's fastest-growing counties, Hamilton County's 2026 assessment growth, and Monroe County rental assessments.
The Assessment Lag: Which Sales Drive Which Bill
Indiana adjusts assessed values every year under IC 6-1.1-4-4.5, which requires the DLGF to run a system of annual adjustments using mass appraisal "within statistical measures of accuracy." In practice, that means a ratio study comparing assessed values to sales. The DLGF's December 30, 2025 ratio study memo sets the sales window:
The assessing official may use sales of properties from the period from January 1, 2025, to December 31, 2025, for the January 1, 2026, assessment date.
The memo allows a different 12-month window that ends no more than two months before January 1, such as November 1, 2024 through October 31, 2025. Thin townships may reach back up to five years, with time adjustments. Each county needed an approved ratio study before delivering its 2026 pay 2027 roll to the auditor by July 1, 2026 (IC 6-1.1-5-14).
| Assessment date | Primary sales window | Taxes payable |
|---|---|---|
| January 1, 2026 | Calendar 2025 sales | 2027 |
| January 1, 2027 | Calendar 2026 sales (if the same pattern holds) | 2028 |
The 2027 row follows the 2026 memo's pattern; the DLGF has not yet issued 2027 guidance.
Note
Summer 2026 sales do not touch your pay-2027 bill. That bill rests on the January 1, 2026 assessment, which was trended on 2025 sales. Summer 2026 sales feed the January 1, 2027 assessment, which shows up on the Form 11 you get in 2027.
What Late-Summer 2026 Means for Your Next Assessment
Three points follow from the data:
- Expect modest, not zero, upward trending for 2027. With statewide medians running 3% to 5% above 2025 all year, 2026 sales will generally support higher values. That is milder than the 12% statewide assessed value growth of 2025.
- Local markets will diverge. Ratio studies are run by township and property class, not statewide. A Bloomington-area home and a Fort Wayne home will not get the same factor.
- The market is not the only thing that moves values. The DLGF updated location cost modifiers for January 1, 2026, and depreciation is recalculated every year. Our DLGF 2026 cost-schedule explainer covers those non-market changes.
Tip
Under $150,000, IAR's mid-year report found sellers cut prices 10% on average and buyers negotiated another 2.7% off. In that tier, compare your assessment to actual 2025 and 2026 closing prices, not list prices.
What to Do Now
- Check your 2026 Form 11. Under IC 6-1.1-15-1.1, the appeal deadline is June 15 of the assessment year if the notice was mailed before May 1. If it was mailed on or after May 1, the deadline is June 15 of the year your tax bill is mailed. See what to do with a Form 11.
- Save comparable sales now. Arm's-length 2026 sales near you are your evidence against the 2027 assessment. Our guide to comparable sales evidence for PTABOA appeals explains how to pick them.
- Review the basics. If the trending process is new to you, start with how Indiana property tax assessments work.
- Compare your value to the market. Use our property lookup tool to set your assessed value beside nearby sales. If the gap is real, our tax appeal service builds the file.
