New Construction vs Existing Home in Kansas City: The Honest Math for 2026
By Joe Nelson — Retired Air Force, Nelson Home Group Team Leader and Mortgage Loan Originator
The choice between new construction vs existing home in Kansas City comes down to three things: how long you plan to stay, whether the neighborhood is still being actively built out, and whether you can absorb the per-square-foot premium new construction carries in the Midwest. National headlines say new construction is now cheaper than existing homes. In Kansas City, that math does not hold. Plan to stay at least 7 to 10 years, or lean toward an existing home in an established neighborhood.
What’s the actual price difference between new construction and existing homes in Kansas City right now?
The national data is misleading, and you need to know why before you let it drive your decision.
According to the most recent U.S. Census Bureau and HUD report, the median sales price of new homes sold in March 2026 was $387,400, down 6.2 percent from a year earlier. The median existing-home price in the same month was $408,800, per the National Association of Realtors. On paper, new construction is now cheaper than existing nationally.
That headline hides the story. Builders nationally are pushing smaller, less expensive inventory to chase affordability-pressured buyers. The average sales price for new construction in March 2026 was $503,100, more than $115,000 above the median, which tells you the luxury end of new construction is pulling the average way up while production builders are slicing the bottom end thinner.
On a per-square-foot basis the picture shifts again. Per Q3 2025 Realtor.com data, new construction nationally averaged $218.66 per square foot versus $226.56 for existing homes. Nationally, new is now slightly cheaper per square foot. But that average is driven by the South and West, where builders are flooding the market.
In the Midwest, where Kansas City sits, the per-square-foot premium for new construction over existing is still more than 50 percent higher than the national average. The median existing-home price in the Midwest in March 2026 was $315,500. Most new construction in KC’s active submarkets starts around $500,000 and runs into the $700s and $800s. There are outliers below $400,000 scattered across the metro, and plenty of new construction above $850,000 in luxury submarkets, but the heart of KC new construction sits between $500K and $800K.
National headlines say new construction is cheaper than existing homes. In Kansas City, that math does not hold.

What happens if you need to sell your new construction home in 2 or 3 years?
This is the question most buyers do not ask before they sign, and it is the one that hurts most when they have to sell early.
If you buy new construction in a development that is still being actively built out, and life forces a sale before the neighborhood is finished, you are competing head-on against the builder. The builder is selling brand-new inventory two streets over, with a model home, sales reps, and rate-buydown incentives that you cannot match. Your lightly used two-year-old home looks worse against that pitch every weekend.
Buyers gravitate to the new option. Your home sits, or you sell under what you put into it. The new-car comparison applies: you took the depreciation-like hit on the front end by paying the per-square-foot premium, and now the market has a fresher product right next door.
The good news, and the difference from a car, is that real estate is generally an appreciating asset. Time fixes most of this. If you can stay seven to ten years, the development is fully built out, the trees have grown in, the neighborhood has matured, and the per-square-foot premium you paid up front has been more than absorbed by appreciation. The existing-home market has posted year-over-year price increases for 33 consecutive months as of March 2026, per NAR. That math works in your favor if you can stay put.
The exposure is highest with production builds in actively selling developments. Pure custom builds at the top end behave differently, since you are not competing against an identical model home next door, but the per-square-foot premium still works against you on an early resale.
If your timeline is shorter than seven years, or your life situation is unstable enough that you might need to move on short notice, lean toward an existing home in an established neighborhood where the market is mature and your home is not the third-best option next to the builder’s model.
Do builder rate buydowns actually save you money, or are they a trap?
This is the angle most KC agents will not walk you through, because most KC agents are not also licensed mortgage originators. We are. Here is the honest version.
Builders across Kansas City are offering aggressive rate buydowns right now. The deals are real. A 2-1 buydown, where your rate is reduced by 2 percent in year one, 1 percent in year two, and lands at the note rate from year three forward, can save a buyer real money in the first two years. A permanent buydown can save real money over the life of the loan.
Here is what builders will not always volunteer: they cannot legally require you to use their preferred lender. The Real Estate Settlement Procedures Act (RESPA, enforced by the Consumer Financial Protection Bureau) prohibits builders from making the use of a specific lender a condition of the sale. They can recommend a preferred lender. They can offer financial incentives, including buydowns, closing cost credits, and free upgrades, if you use that lender. They can require you to be pre-qualified by their lender to verify you can afford the home. They cannot mandate that you close with them.
Builders cannot legally require their preferred lender. They can incentivize. They cannot mandate. That distinction is worth thousands.
The math we run for our clients looks like this. A builder’s buydown offer might be worth $15,000 in saved interest over the first two years. If the builder’s preferred lender is charging you a quarter-point higher rate, higher fees, or pushing you into a less competitive loan structure over the full life of the loan, that $15,000 short-term win can cost you $25,000 to $40,000 over a 30-year mortgage. Sometimes the builder’s deal is genuinely the best deal. Sometimes it is not. You need someone running both scenarios with you, not pitching you one side.
As both Realtors and a licensed mortgage originator, we run the full prequalification scenario in-house. We compare the builder’s offer side by side against a portable loan structured to your situation, on the same screen, before you sign anything. If you want to start with raw numbers, our mortgage calculator is a fine starting point, but the real conversation starts when we sit down with your income, credit, and timeline.
Where in Kansas City does each option make the most sense?
New construction at every price point exists across the Kansas City metro. Concentrations vary by submarket, but availability does not.
The most active production new construction sits across both states: Liberty, Smithville, Parkville, and the rest of the Northland on the Missouri side; Lee’s Summit, Blue Springs, and the I-470 corridor; and Olathe, Spring Hill, Gardner, Shawnee, and parts of Overland Park and Lenexa on the Kansas side. Hunt Midwest, DR Horton, Hakes Brothers, Robertson Construction, Syler Construction, and Encore Building Company are all active across these submarkets.
Luxury and custom new construction concentrates more heavily in Johnson County, particularly Leawood, parts of Overland Park, and executive Lee’s Summit, but plenty of million-dollar custom builds happen in Parkville, Liberty, Smithville, and the rest of the Northland too. Submarket does not equal price band. Buyers comparing new construction should look broadly.
Existing inventory is the only option in established neighborhoods where build-out finished a generation ago: Brookside, Waldo, Prairie Village, Mission Hills, Mission, parts of Lenexa, the older sections of Independence, and most of historic Kansas City proper. If location, mature trees, larger lots, and proximity to established commercial corridors matter to you, existing is your only path. New construction in those zones means a tear-down at premium pricing, which is its own conversation.

The tax structure, school districts, and property tax math change the new vs existing decision differently depending on which side of State Line Road you land on.
Who should buy new construction and who should buy existing?
The framework holds at any price point, whether you are looking at a $385,000 starter or a $1.2 million custom build.
New construction wins if: you plan to stay at least seven to ten years; you value low-maintenance and modern energy efficiency; you want input on finishes, layout, or full custom; the development you are buying into is at or near full build-out (not still actively selling phase three); the builder’s financing genuinely beats portable alternatives when run head to head; and warranty coverage matters to your risk tolerance.
Existing wins if: your timeline is shorter than seven years or your life situation is uncertain; you want an established location with mature trees and existing neighborhood character; larger lots matter to you; you can absorb normal maintenance in exchange for a per-square-foot discount; or you simply prefer not to compete against a builder selling brand-new inventory if you ever need to resell.
Neither option is universally better. The buyers who get this decision right are the ones who run their actual numbers, look at their actual timeline honestly, and pressure-test the financing math before they sign anything.
Frequently Asked Questions
Is new construction always more expensive than an existing home in Kansas City?
No, not always. As of March 2026, the national median price for a new home was actually below the median for an existing home, according to Census Bureau and NAR data. But on a per-square-foot basis in the Midwest, new construction still carries a substantial premium over existing homes. In Kansas City specifically, most new construction lives in the $500,000 to $800,000 range, while the Midwest median existing-home price sits at $315,500. The per-square-foot premium is real here.
Can a builder require me to use their preferred lender?
No. Federal law under the Real Estate Settlement Procedures Act (RESPA), enforced by the Consumer Financial Protection Bureau, prohibits builders from requiring buyers to use a specific lender as a condition of the sale. Builders can recommend a preferred lender, offer incentives like rate buydowns or closing cost credits for using that lender, and require you to be pre-qualified by their lender to verify you can afford the home. They cannot mandate that you close with them. You always have the right to shop your loan.
How long should I plan to stay in a new construction home?
Generally seven to ten years. The per-square-foot premium you pay up front, combined with the resale challenge of competing against the builder in an actively developing neighborhood, makes shorter holds risky. If your timeline is uncertain or shorter than five to seven years, an existing home in an established neighborhood usually carries less downside on resale.
What is a builder rate buydown and is it worth it?
A builder rate buydown is an incentive where the builder pays your lender to reduce your interest rate, either temporarily (such as a 2-1 buydown where your rate is reduced 2 percent in year one, 1 percent in year two, then resets to the note rate) or permanently. The buydown is real money saved on your mortgage payment in the short term. Whether it is worth it depends on the rate, fees, and full loan structure offered by the builder’s preferred lender compared to what you could get from a portable lender. Sometimes the builder’s deal is genuinely better. Sometimes the long-term cost of the preferred-lender loan wipes out the buydown savings. The only way to know is to run both scenarios side by side.
Where in Kansas City should I look for new construction vs existing homes?
New construction is most concentrated in Liberty, Smithville, Parkville, and the Northland; Lee’s Summit, Blue Springs, and the I-470 corridor; and Olathe, Spring Hill, Gardner, Shawnee, and parts of Overland Park and Lenexa. Luxury and custom new construction is heavier in Johnson County, particularly Leawood and executive Overland Park, but happens across the metro at every price point. Existing inventory is the only option in established neighborhoods like Brookside, Waldo, Prairie Village, Mission Hills, and the older sections of Independence and Kansas City proper.
