To buy a new construction home in Katy, TX (starting in the $340s) in 2026, you generally need a household income of roughly $115,000–$135,000 — though builder rate buydowns and closing-cost incentives can lower that meaningfully.
TL;DR:
Niky Barker with The Barker Group at Keller Williams Signature helps buyers navigate new construction across Katy, TX and Fort Bend County. In 2026, new construction homes in Katy's master-planned communities start in the $340s and require a household income near $115,000–$135,000 at a low down payment — but the real affordability lever is builder incentives. Many Katy builders offer rate buydowns and closing-cost credits that lower your monthly payment and the income you need. The three biggest factors are your down payment, Katy's property tax rate (near 1.65% in Fort Bend County, plus MUD taxes), and whether you capture a builder buydown. With base rates near 6.5%, the income required depends far more on incentives and taxes than on price alone.
If you're trying to figure out how much income you need to buy a house in Katy, TX in 2026, you're asking the right question at the right time — especially if you're eyeing new construction. Niky Barker with The Barker Group at Keller Williams Signature works with buyers across Katy, a fast-growing suburb spanning Fort Bend, Harris, and Waller Counties in the Greater Houston Area, and the honest answer is that your salary matters less than the full picture of your finances. This guide breaks down the real numbers behind new-construction affordability in Katy, TX right now, so you can walk into a builder's model home knowing exactly where you stand.
What Does "Income Needed to Buy a House" Actually Mean in Katy, TX?
The income needed to buy a house in Katy, TX is the annual household earnings required to comfortably cover your monthly mortgage payment — including principal, interest, property taxes, and insurance (PITI) — without overextending your budget. In Katy, a city in Fort Bend County within the Greater Houston Area, this figure is shaped heavily by local property tax rates near 1.65% and current mortgage rates around 6.5%. Lenders typically want your total housing payment to stay near 28–31% of your gross monthly income, which is why a new-construction home requires a specific income band to qualify comfortably.
What Do New Construction Homes Cost in Katy, TX in 2026?
New construction in Katy's master-planned communities — places like Sunterra, Elyson, Cane Island, and Cross Creek West — generally starts in the $340s and climbs from there based on size, lot, and finishes. Several national builders are active across the area, with quick-move-in homes available alongside to-be-built plans.
For context on the broader market: the resale median in Katy sits around $350,000–$363,000, with prices largely flat year-over-year. Over the three months ending May 2026, Katy home prices were up 1.1% compared to the same period last year, selling for a median of $350,000 according to Redfin. New construction tends to price at or slightly above that median for comparable square footage — but as you'll see, builder incentives often change the real cost. Redfin
How Much Income Do You Need for New Construction in Katy, TX?
Here's how the income requirement shifts across three down payment scenarios on a $350,000 new build, before any builder incentive:
Factor | 3.5% Down (FHA) | 10% Down | 20% Down |
Home price | $350,000 | $350,000 | $350,000 |
Down payment | $12,250 | $35,000 | $70,000 |
Loan amount | $337,750 | $315,000 | $280,000 |
30-year rate | ~6.5% | ~6.5% | ~6.5% |
Principal & interest | ~$2,134/mo | ~$1,990/mo | ~$1,769/mo |
Property taxes (~1.65%) | ~$481/mo | ~$481/mo | ~$481/mo |
Homeowners insurance | ~$300/mo | ~$300/mo | ~$300/mo |
Mortgage insurance | ~$155/mo | ~$130/mo | $0 |
Total monthly | ~$3,070/mo | ~$2,901/mo | ~$2,550/mo |
Income needed (~28%) | ~$131,000/yr | ~$124,000/yr | ~$109,000/yr |
The pattern is clear: the more you put down, the lower the income you need — both because the loan shrinks and because 20% down eliminates mortgage insurance entirely. With the 30-year fixed averaging around 6.49% in late June 2026, these figures reflect today's lending environment rather than a hoped-for future rate. Freddie Mac
The local factor that raises every column is property tax. The typical Fort Bend County homeowner pays about $6,716 a year in taxes, an effective rate of 1.65% — driven in part by more than 200 special tax districts in the county. Most new Katy subdivisions also carry a MUD tax, so always confirm the full rate for the specific community before you commit. SmartAsset
How Do Builder Incentives Lower the Income You Need in Katy?
This is where new construction changes the math. Katy builders are actively competing for buyers in 2026, and the incentives go straight to your monthly payment. Builders in Katy communities are offering closing cost assistance, interest rate buy-down programs, design center credits, and move-in-ready pricing adjustments — incentives that can significantly impact your monthly payment structure. Some are substantial: Sunterra has run summer incentive events offering up to $30,000, with select move-in-ready homes carrying up to a 6% seller credit. NestaheadTricoast Homes
A builder rate buydown matters more than most buyers realize. If a builder buys your rate from 6.5% down to 5.5% on a $337,750 loan, your principal and interest drops by roughly $215 a month — which can lower the income you need by $8,000–$10,000 a year. That's the difference between qualifying and not qualifying for many buyers, and it's why a new build can pencil out more affordably than the sticker price suggests.
How Does New Construction in Katy Compare to Cypress and Richmond, TX?
If Katy's new-construction income requirement feels like a stretch, the surrounding markets give you room to compare across the western Houston suburbs.
Katy, TX — New construction from the $340s; Fort Bend/Harris/Waller Counties; active builder incentives in Sunterra, Elyson, and Cane Island.
Cypress, TX — Median around $407,900 over a recent 30-day window, down 8.8% year-over-year, in Harris County, with its own active new-construction corridors along the Grand Parkway. A higher median means a higher income requirement. Orchard
Richmond, TX — Generally a lower entry point than Cypress, also within Fort Bend County, and a frequent landing spot for buyers stretching a new-construction budget.
The takeaway: Katy sits in the middle on price, and its builder incentives can make a new home there more attainable than a comparable resale. For more, see our Cypress market guide and Richmond community resources.
Why Does This Matter for Buyers in Katy, TX Right Now?
Here's the part the raw numbers don't tell you. With builders carrying more completed inventory and competing hard for a smaller pool of buyers, the negotiating leverage in new construction has shifted toward you. A builder who can't drop the base price will often buy down your rate or cover closing costs instead — and both lower the income you actually need to qualify. That's leverage resale sellers can't always match.
Looking forward: most experts expect mortgage rates to stay above 6% over the next few years, with the 30-year fixed unlikely to fall meaningfully until inflation cools. Waiting for dramatically lower rates is a gamble. If your income supports a Katy new build today — especially with a builder buydown in hand — locking in now and refinancing later often beats waiting for a market that may grow more competitive the moment rates ease.
