BAH Housing Near Scott Air Force Base: What to Expect

An E-5 with orders to Scott lands with a number already in her head: $2,436 a month, the 2026 Basic Allowance for Housing rate for her grade and dependency status. She assumes that number will stretch about the same whether she ends up in Shiloh, O'Fallon, Mascoutah, or Belleville. It doesn't. The paycheck is identical in all four towns. What it buys is not.

That gap between a fixed allowance and four different housing markets is the thing most PCS guides skip past on their way to a list of neighborhoods. It's also the detail that decides whether a family closes on a house in 45 days or spends their first six months renting while they figure out the math.

The Number That Doesn't Move

BAH isn't set by ZIP code or neighborhood. It's set by Military Housing Area, and Scott Air Force Base falls entirely inside the St. Louis, MO MHA. That means every off-base address around the base, from a subdivision touching the Shiloh gate to a historic block in downtown Belleville, draws the exact same rate for a given rank and dependency status. Move ten miles in any direction and your allowance doesn't change at all.

For 2026, effective January 1, the rates by pay grade with dependents look like this:

An E-5 without dependents draws $1,947 a month, roughly $500 less than the with-dependents rate for the same grade. And this year's increase was sharper than most bases saw. National BAH rose an average of 4.2% from 2025 to 2026. At Scott, trackers put the base's own increase higher than that average, with figures ranging from around 5.9% depending on which grades are averaged, up to a documented 8.1% year-over-year jump for an E-5 with dependents, whose rate climbed from $2,253 in 2025 to $2,436 in 2026. The sources don't fully agree on the single best percentage to quote, which is normal when different trackers weight different grades, but they agree on the direction: Scott's allowance grew faster than the national trend this year.

That's a real increase in buying power arriving at the same time incoming families are house-hunting. It doesn't change where the number goes furthest. It just means everyone showed up this year with a slightly bigger number in their pocket.

Same Check, Four Different Towns

Because the allowance is flat across the MHA, the real decision is which town's price curve and commute you want to match it against.

Shiloh sits right against the base, close enough that some subdivisions are a few minutes from a gate. It's also the only one of the four with a MetroLink stop, the Shiloh-Scott station, which can replace a daily drive entirely for some households. Three-bedroom rentals here have run in the neighborhood of $1,300 to $1,750 a month, and for-sale inventory leans toward newer single-family subdivisions and townhomes.

O'Fallon runs a 10 to 15 minute commute to base and carries a reputation among incoming families for newer subdivisions and a well-regarded high school district known for a strong AP program and diverse extracurriculars. It's frequently the first town PCS families put on their list, which also means it tends to see some of the more competitive pricing in the group.

Mascoutah sits just south of the base with one of the shortest drives to any gate. It shares the same school district, CUSD 19, that serves children living in on-base housing, so families who want continuity with the base community without living on it often land here. It also tends to run a smaller price point than O'Fallon or Shiloh.

Belleville is the outlier on distance, at roughly a 20 minute drive to the main gate, but it offers the widest range of home ages and price points of the four, including pockets that undercut the other towns significantly. It's also the county seat, home to Southwestern Illinois College, and has a historic downtown that reads differently than the newer subdivisions closer to base.

Across all four, a rough price map looks like this: entry-level homes, smaller or older, start around the low $150,000s and run into the high $200,000s. Typical three-bedroom homes in the closer-in towns fall from the upper $200,000s into the low $400,000s. New construction in select subdivisions can push past $420,000, with both price and pace picking up during peak PCS season in late spring and summer.

Line that up against a fixed $2,436 monthly allowance and the picture changes by town. In Belleville, that allowance covers a mortgage payment with real room left over on a wider set of homes. In O'Fallon or Shiloh, the same allowance is working against a tighter, pricier band of inventory, in exchange for a shorter commute or a specific school assignment.

Why Cheap Doesn't Mean Easy

Here's the part that catches people off guard. Low prices at Scott don't automatically mean an easy search, because the buyer pool competing for that inventory is bigger and steadier than a typical Midwest base town.

Scott generates roughly $12.9 billion in annual economic activity across southwestern Illinois and supports close to 40,000 jobs, according to a recent regional economic impact study prepared for the Leadership Council of Southwestern Illinois. A meaningful share of that isn't payroll that leaves when someone retires. More than 11,000 people in the region have completed 20 years of service and draw a full pension, and when family members are counted, that population runs closer to 18,000. Many of them transition directly into civilian jobs on or near the base instead of relocating elsewhere once they separate or retire.

That means the same starter homes in O'Fallon, Shiloh, Mascoutah, and Belleville that PCS families are shopping also draw retirees and veterans who already live in the area, have equity, and aren't racing an orders timeline. The result is a buyer pool that's larger and less rate-sensitive than the price points alone would suggest, and inventory that holds up better than you'd expect in towns where the median home is still well under the national average.

The affordability headline and the competition headline are both true at the same time. That's the part a sticker price can't tell you.

What This Means When You're Running Your Own Numbers

Because BAH won't move once you pick a town, and because inventory pressure varies by town independent of price, the smarter framing isn't "which town is cheapest." It's "which trade-off am I actually willing to make."

If a short commute and transit access matter most, Shiloh's MetroLink stop and gate proximity are worth the tighter price band. If school continuity with on-base families matters, Mascoutah's shared district with CUSD 19 is a real point in its favor, not just a convenience. If your allowance needs to stretch furthest and you're comfortable with 20 minutes on the road, Belleville's broader price range gives you more room to negotiate or to buy up.

One more mechanical detail worth knowing before you run comparisons: lenders count BAH as income when you apply for a VA loan, so the $2,436 a month isn't just a housing subsidy on paper, it's part of your qualifying income on a mortgage application. That's worth confirming with a VA-savvy lender early, before you fall for a house that's a stretch in one town when the identical allowance would put you comfortably ahead in another.

A Few Straight Answers

Does my BAH change if I buy instead of rent? No. The rate is fixed by pay grade, dependency status, and Military Housing Area, regardless of whether you rent, buy, or live on base.

Will my BAH drop if home prices near Scott fall? No. Once you're locked in at a duty station, rate protection keeps your BAH from dropping due to market changes. It only changes if your pay grade or dependency status changes.

Can I really use the same allowance in any of these four towns? Yes, as long as your permanent duty station stays Scott AFB. The number on your Leave and Earnings Statement doesn't care which town you pick. What changes is what that number buys you once you get there.

Running these numbers against four towns and a moving deadline is exactly the kind of math that benefits from someone who's done it before. Veterans PCS Group connects incoming families with vetted veteran and military-spouse agents who work this exact market around Scott, plus VA loan guidance and a move-in cash bonus program to help offset the cost of getting there.
