If you have looked at New Carlisle in the last six months, you have probably seen the same headline number circulating: home values within a mile and a half of Amazon's data center campus have appreciated far faster than the rest of St. Joseph County. It is a real number, and it has done real work convincing buyers to move quickly. It is also the wrong number to plan a purchase around.
The interesting story is what sits underneath it. The campus is not the mechanism. It is the accelerant on a mechanism that already existed here, and the mechanism has a timeline attached. If you understand the timeline, you can tell whether you are buying at the front of the repricing or paying for something that has already happened.
The 49% number, unpacked
The number comes from an Integra Realty Resources appraisal study that looked at property values for 80 homes near data centers in St. Joseph County, LaPorte County, Clark County and Allen County, and when combining the data for all four counties, found home values grew 42% for homes within 1.5 miles of data centers, compared to 41% in the local markets. Broken out by county, only St. Joseph County saw homes near data centers gain more value than the local market average, with prices near Amazon's New Carlisle campus rising 49% compared to an average 32% increase countywide, while properties within 1.5 miles of large-scale data centers in Allen, LaPorte and Clark counties actually gained less value than their county average by 1%, 6% and 9%, respectively.
That last part is the tell. Three of four Indiana data center sites underperformed their local market. Only New Carlisle outran it. What is different here is not the presence of a data center. It is that New Carlisle had almost no inventory to sell before Amazon arrived, so the transactions that did close during the study window were disproportionately land, acreage, and a small number of homes near a campus that the buyer pool had already decided was going to reshape the town.
You can see the fingerprint in the listing data. In May 2026, New Carlisle homes were listed to buy for a median price of $599K. For comparison, in July 2026 La Porte homes were listed to buy for a median price of $344K, a 4% decrease from July 2025. Two towns roughly a half hour apart, and the listing medians are almost $250K apart. That is not a story about data center proximity boosting nearby home values. It is a story about what is currently on the market in a town with a very small housing stock.
What is actually for sale in New Carlisle right now
The active inventory skews toward two categories that pull the median upward. The first is speculative land near the campus. Listings openly advertise proximity, with parcels marketed as 1 mile from the multi-billion Amazon data center on 16.67 acres along HWY 2 and adjacent parcels described as short distances from the same campus.
The second is a thin stack of newer construction and larger custom homes in subdivisions like Wintergreen Meadows and Stone Oak Estates, both of which sit in the New Prairie school district. On the resale side there are historic in-town houses, a handful of fixer-uppers, and very little in the middle.
Here is what that produces at the neighborhood level as of summer 2026:
| Where you are looking | Recent listing median | What that price tends to include |
|---|---|---|
| New Carlisle (May 2026, Movoto) | $599K | Newer construction on larger lots, land parcels marketed on Amazon proximity, custom builds in New Prairie schools |
| La Porte (July 2026, Movoto) | $344K | A broader mix of resale housing stock in an established market |
| La Porte County median list (May 2026, Realtor.com via FRED) | ~$305K | Countywide baseline including Michigan City |
Reading the New Carlisle median as "what a house costs there" overstates the entry point. Reading it as "what the current listings are asking, weighted heavily toward acreage and new builds tied to campus proximity," is closer to the truth.
The three 2026 and 2027 dates that will move prices more than the campus itself
The campus is being built. That part is settled. Amazon Web Services has invested $13.8 billion in its data center campus in St. Joseph County, surpassing its original $11 billion goal, and Amazon and local leaders met in late July to discuss progress, with the campus expected to include about 30 buildings, with approximately 18 currently operational. What is not settled, and what actually determines whether the current premium holds or compresses, is three pieces of infrastructure and policy still in motion.
- The State Road 2 / Larrison Boulevard interchange. A diverging diamond interchange at State Road 2 and Larrison Boulevard has yet to begin construction. Until it does, construction traffic and shift-change congestion move through the same roads residents use. That is a real, measurable friction that any commuter buying near the campus should price in.
- The AEP transmission build-out. The campus needed a purpose-built power delivery scheme, and AEP is building two new 345 kV delivery substations, Larrison Drive and New Prairie, plus fault-duty upgrades at the existing Olive station, a package of about $185 million targeting an initial 1.1 GW of service by December 2026. That target date is when the campus can actually scale operations. It is also when the local labor and contractor demand shifts from construction to operations.
- The TIF and abatement phase-in. In August 2024, the St. Joseph County Council approved an economic-development agreement granting Amazon a 50% real-property tax abatement for 10 years plus an approximately 85% exemption on technology equipment for 35 years, and the campus sits inside a New Carlisle tax-increment financing district with property taxes phasing in to full effect in 2027. The first hard number came in June: the county's first annual abatement-compliance review reported that $8.9 billion of the $11 billion had been invested as of January 1, 2026, including $1.7 billion of assessed real property, and on those values, Amazon is projected to pay about $12.5 million in property taxes in 2027, abatements applied.
That $12.5 million is the moment abstract benefit becomes a line in a budget. It is also when the state and county start negotiating in earnest about how much of that revenue reaches New Carlisle's own services, which is what long-term buyers should be watching. A town of roughly 2,000 residents absorbing thousands of construction workers and eventually hundreds of permanent staff needs the tax base to catch up.
Where the friction actually shows up in a transaction
If you are close enough to write an offer, a few specific frictions are worth knowing about here that will not appear on a portal listing.
Appraisals get complicated near active industrial construction. Comps within the 1.5-mile ring are thin, and appraisers are being asked to interpret the 49% figure against a very small sample. A conservative appraisal can undercut a contract price that felt reasonable at listing. Sellers should expect longer appraisal timelines. Buyers should keep appraisal contingency language tight.
Utilities are not uniform. Some newer subdivisions have city water and sewer. Many parcels being marketed on Amazon proximity are on well and septic. A parcel description that reads as "just minutes from the campus" can still require a well drilling and a septic design before you can build. Ask for the utility map before you fall in love with the location.
Grid-cost allocation is a live issue. Citizens Action Coalition has flagged that I&M is shifting more than $400 million in costs to connect Google in Fort Wayne and Amazon in New Carlisle data centers to the grid onto their customers in Cause No. 46301. That does not affect a purchase price directly, but it does affect the operating cost of every home on the I&M system, which residential appraisers do not adjust for.
Wetlands and drainage matter more here than most Northern Indiana buyers expect. Environmental review documented that the Amazon data center is destroying 10 acres of wetlands in New Carlisle, in a state that under HEA1383 has very weak protections for wetlands. For a homebuyer, the practical read is that any parcel adjacent to former wetland or with a drainage swale tied to campus-area grading deserves a hard look during due diligence. A local surveyor can tell you whether your future backyard is upstream or downstream of the site prep.
A short FAQ
Is now a good time to buy in New Carlisle, or should I wait? Wait for what, is the better question. If your reason to buy is a job tied to the campus, the labor market clock beats the housing market clock. If your reason is investment, the two dates worth watching are the Larrison Boulevard interchange starting construction, which relieves a real friction, and the 2027 TIF phase-in, which will reveal whether local services keep pace with growth.
Does the AWS campus expansion elsewhere in Indiana change things here? It does. Amazon announced plans to invest an estimated $15 billion in Northern Indiana to build new data center campuses, which is additional to the $11 billion investment previously announced in St. Joseph County and will expand infrastructure to new sites across Indiana. That means New Carlisle is the template, not the whole story, and buyers who want data-center-adjacent exposure may soon have other Indiana options that reset the scarcity premium here.
How do I compare New Carlisle to La Porte or South Bend on a real basis? Look past the median. In La Porte the same budget generally buys established resale stock near lakes and downtown. In South Bend it buys deeper inventory across a wider range of neighborhoods. In New Carlisle it currently buys either newer construction with New Prairie schools or land you will still need to develop. The right comparison is what your money actually buys, not what the headline median says.
If you are weighing New Carlisle against La Porte, South Bend, or the smaller communities in between, the answer usually comes down to which timeline you are buying into and which frictions you can absorb. That is worth a conversation before you write an offer.
