A second anchor: what SK hynix means for West Lafayette housing

The previous note made the case for West Lafayette without mentioning what is being built on its north side. That was deliberate. The town's value does not depend on a new employer. But a new employer is coming, it is large, and it has a calendar, so the question for anyone who owns a home here or is thinking about buying one is what the numbers say about the next three years.

SK hynix broke ground on 27 August 2026 on an advanced packaging fabrication and research facility for high-bandwidth AI memory in Purdue Research Park. The investment is about $4 billion, and it will be the first production hub for this class of memory in the United States. At the groundbreaking the project was roughly 7 percent built and on schedule. The first clean room is planned for October 2028, with volume production in late 2029.

Two employment figures circulate, and they are not the same thing. The plant itself is expected to employ about 1,000 people when production begins. The larger figure, an estimated 7,000 jobs, counts direct, indirect and construction employment across the region over the life of the project. Both are real; only the first is a payroll at one address in West Lafayette.

Recall the split from the previous note. West Lafayette's permanent, non-student community is in the low-to-mid 20,000s. A thousand skilled hires is a 4 to 5 percent addition to that community before spouses and children, and the hires will look like the people already here: engineers, technicians and researchers with the education and income profile of the Purdue faculty and Research Park workforce. This is not a new kind of resident for West Lafayette. It is more of the kind the town already has.

The housing they will be looking for is the constraint. Here is the stock they arrive into, from the Census:

U.S. Census Bureau, American Community Survey 2019 to 2023 five-year estimates, West Lafayette city.

The number that matters is 4,434. That is the entire owner-occupied inventory of the city, and 0.9 percent of it is vacant, which in practice means almost nothing is sitting empty. The rental side has room, as a college town always does. The ownership side does not. A thousand households arriving over two or three years into a pool of 4,434 homes that turns over slowly is the definition of a supply-constrained market.

The current figures for the West Lafayette area, from the Indiana Regional MLS for July 2026, are on the community page and worth restating here: a median sale price of $364,500, up 9.6 percent year over year, 29 days from list to under contract, 147 homes listed on an average day, and sellers receiving 96 percent of asking. That is already a strong seller's market, and it reflects demand from the existing employer base rather than the plant, whose hiring has not begun.

The most direct answer to the supply question is Millbrook, a master-planned community by Estridge Homes on more than 300 acres immediately north of the plant site, which broke ground in April 2026. The plan is 771 single-family homes priced from roughly $400,000 to $1 million, plus 400 to 500 townhomes and multi-family units, built out over about ten years.

Set that against the 4,434 owner-occupied homes that exist today and the scale is clear: one subdivision would expand the city's ownership stock by about 17 percent. That is a large number, and it is also a ten-year number. Homes are delivered in phases, and the plant's hiring window opens in 2028 and 2029, well before the community is built out. The 2024 Greater Lafayette Regional Housing Study, prepared under the state's READI program, set a goal of 11,838 new housing units across the region this decade. Millbrook is about 11 percent of that on its own, and the study was sizing demand from the whole employer base, not one plant.

It is worth being precise about how diversified Greater Lafayette's employment already is, because that diversification is what makes the plant an addition rather than a bet. Purdue University and the Purdue Research Foundation anchor the west side, and the Research Park is home to more than 250 companies. Subaru of Indiana Automotive employs more than 6,500 people in Lafayette at the only Subaru assembly plant outside Japan. Wabash National, headquartered in Lafayette, employs about 5,700 people worldwide. Caterpillar's Large Engine Center employs about 1,900 and is in the middle of a $725 million expansion that adds a further 100. Cook Biotech employs about 275 in the Research Park. Two hospital systems, IU Health Arnett and Franciscan Health, serve the region from Lafayette. SK hynix arrives as one more anchor in a market that already had several, which is a different proposition from a single-employer town waiting on a single decision.

Owners in West Lafayette are holding an asset in the most supply-constrained segment of a market that is about to receive a dated, documented increase in high-income demand. The homeowner vacancy rate says there is no slack. The construction timeline says the demand arrives in 2028 and 2029. The new-construction pipeline says relief is real but phased over a decade. That is a favorable position, and it is one worth planning around rather than reacting to: the question is not whether to sell, but when in that window a particular house and a particular family are best served by selling.

Buyers should read the same numbers the other way. The owner-occupied market is small, it is tight now, and it will be tighter when the plant staffs up. Buying ahead of the 2028 window, in an established neighborhood rather than waiting on a phase release, is the position that the data favors. The town you are buying into is the one described in the previous note: the most educated community of its size in the state, a nationally ranked school district, and a campus that keeps a small city connected to the world. The plant does not change that story. It adds a second reason to believe it.
