Cost to Build a House in Des Moines vs. Buying an Existing Home — Which Wins?
If you are shopping for a home in the Des Moines area right now, at some point the question comes up: should we just build?It is a fair question and not an easy one to answer. The right choice depends on your budget, your timeline, and honestly what you actually want from the home you end up in. This post walks through the real numbers on both sides so you can make that call with your eyes open.
What the Des Moines Market Looks Like Right Now
Before comparing the two options, it helps to understand what you are working with. The median sale price of a home in Des Moines was $200,000 as of January 2026, with homes sitting on the market an average of 64 days. That is longer than last year, which means buyers have a bit more room to breathe than they did a few years ago. But inventory across the metro is still lean. When you expand to the broader suburbs, the Des Moines metro median listing price was $334,995 in December 2025. The gap between city prices and suburban prices matters a lot here because where you want to live changes the math on both buying and building considerably.
The Real Cost to Buy an Existing Home in Des Moines
Most people start here because it feels like the simpler path. You find a house, you make an offer, you move in. But the full cost picture is rarely just the purchase price.
Purchase Price
The average Des Moines home value sits around $190,948, up 5.5% over the past year. If you want to be in Ankeny, Waukee, Clive, or Urbandale, you are looking at meaningfully higher numbers.
Closing Costs
On a $285,000 purchase, closing costs in Iowa typically run 2 to 3 percent of the purchase price. That is $5,700 to $8,550 due at closing, on top of your down payment.
Inspection and Immediate Repairs
This is the number most buyers low-ball. The Des Moines housing stock is heavily weighted toward homes built in the 1970s, 80s, and 90s. These are solid homes but they carry deferred maintenance. Budget $5,000 to $25,000 for immediate repairs or updates depending on the age and condition of the specific property. That range covers things like a new water heater, HVAC service, or outdated electrical panels that show up in Iowa homes of that era regularly.
Renovation Costs Down the Road
A lot of buyers buy with a plan to “update it over time.” That is a real plan but it is also real money. A kitchen update in Des Moines runs $25,000 to $60,000. A primary bathroom renovation runs $15,000 to $35,000. New windows throughout a mid-size home run $8,000 to $20,000. These costs are rarely factored into the initial comparison against a new build, but they should be.
Full Cost Picture on a Typical Existing Des Moines Home
| Item | Estimated Cost |
|---|---|
| Purchase Price | $285,000 |
| Closing Costs | $7,125 |
| Immediate Repairs | $15,000 to $25,000 |
| Near-Term Renovation Plans | $20,000 to $50,000 |
| Realistic Total | $327,000 to $367,000 |
That does not include ongoing maintenance on an aging home over the years ahead.
The Real Cost of Building a Custom Home in Des Moines
Now for the build side, with the same level of honesty.
The Real Cost of Building a Custom Home in Des Moines

| High-end custom | $285 to $365 | $684,000 to $876,000 |

Six Things That Actually Matter When You Compare the Two
The numbers above are a starting point. Here is where the real decision gets made.
1. Upfront Cost
Buying an existing home in Des Moines costs less upfront than building new in most cases. If your budget ceiling is $350,000 and you need to move in the next 90 days, buying an existing home is the practical path. There is no point pretending otherwise.
That said, the gap narrows when you factor in renovation costs on older homes, and it can disappear entirely when you compare a move-in ready new home against an existing home that needs $40,000 to $60,000 worth of updates.
Building wins here.
2. Getting the Home You Actually Want
This is where building pulls ahead and it is not close. When you build with Happe Homes, you pick the floor plan, the finishes, the layout, the storage, the primary suite design, the mudroom setup, all of it. When you buy an existing home, you inherit someone else’s decisions and pay to change the ones that do not work for you.
The kitchen that “just needs updating” is a $35,000 project that most families live with for years before they get around to it. A new build gives you what you want from day one.
Building wins here.
3. Condition and Ongoing Maintenance
A home built to 2026 Iowa energy codes is a different product from a home built in 1985. Better insulation, efficient HVAC, modern plumbing and electrical, windows that actually seal. All of that means lower utility costs and fewer surprises in the first decade of ownership.
Building a house in Iowa takes 6 to 10 or more months on average. Better Business Bureau But once you are in, you are starting from zero on maintenance. No aging systems, no previous owner’s deferred repairs, no guessing what is behind the walls.
Building wins here.

4. How Fast You Need to Move
If you need to be in a home in 60 to 90 days, a full custom build is not going to work. A custom home near Des Moines takes 9 to 12 months from contract to keys under normal conditions. If you have 6 or more months of flexibility, this becomes much less of a factor. And if a move-in ready new home fits your needs, you can often close in 30 to 60 days, which is comparable to buying an existing home.
Buying wins here if you are on a tight timeline.
5. Location
Want a specific street in Windsor Heights, Beaverdale, or the Drake neighborhood? You are probably buying. Undeveloped lots in mature Des Moines neighborhoods are hard to find. Building makes the most sense in growing suburbs like Ankeny, Waukee, Norwalk, and Grimes where communities are actively developing and lots are available.
If you have your heart set on a specific established neighborhood, buying is likely your only realistic option.Depends entirely on where you want to live.
6. Long-Term Value
New homes in desirable Des Moines suburbs have held and appreciated their value well over time. You are buying a home that buyers in 10 to 15 years will still find appealing because it was built to current standards and tastes.
Older homes that have not been updated face increasing buyer resistance as they age. Dated kitchens, older electrical panels, original windows, and layouts that do not match how people live today all become friction points at resale. A new home avoids all of that from the start.
Market analysts project a 3 to 5% increase in median home values across the Des Moines metro, driven by limited housing supply and steady population growth.
Building wins here.
Who Should Buy and Who Should Build
Buying makes more sense if:
- Your budget is firmly under $350,000
- You need to be in a home within 60 to 90 days
- You want to be in a specific established neighborhood
- You are comfortable taking on renovation work
- There is already an existing home on the market that genuinely fits your family
Building makes more sense if:
- Your timeline has 9 to 12 months of flexibility
- You want a home designed around how your family actually lives
- You want modern systems, a warranty, and no deferred maintenance on day one
- You are open to growing suburbs like Ankeny, Waukee, or Johnston
- You plan to stay 7 or more years and want a strong long-term asset
Building makes more sense if:
- You want new construction quality without the full custom timeline
- Your budget falls between what existing homes and full custom builds cost in your target area
- You can move quickly on available inventory
One Thing We Hear a Lot
After 20 years of building homes across the Des Moines Metro, the most common thing we hear from people after they close on a Happe Homes build is some version of: “We wish we had done this sooner.”
Not because buying is the wrong choice for everyone. It is the right choice for a lot of people. But once someone is in a home that was built specifically for how they live, it is hard to imagine having gone the other way.
