Down Payment Assistance in Katy, TX

Ask three Katy neighbors which county they live in and you might get three different answers. Katy sits where Harris, Fort Bend, and Waller counties meet, so one master-planned community can straddle a county line that runs right down the middle of a subdivision. For most things that quirk never matters. For down payment assistance, it quietly does, because the statewide programs set their income and price limits by county.

People move to Katy for Katy ISD, the master-planned communities like Cinco Ranch and Cross Creek Ranch, and the easy run up I-10 to the Energy Corridor. What surprises a lot of them is that assistance reaches more of Katy than they assume, and that two of the three counties run their own programs on top of the statewide help. Here is the full 2026 picture, county lines and all.

Three things Katy buyers assume, and why they are usually wrong

The most common reasons Katy buyers skip assistance do not survive a closer look:

• “We earn too much in Katy to qualify.” Often not. In the Harris and Fort Bend portions of Katy, the TSAHC income limit may reach approximately $126,375 at any household size, and TDHCA’s My Choice Texas Home may reach approximately $173,400. Those ceilings clear a large share of Katy’s dual-income households.
• “It is only for first-time buyers.” For most programs, it is not. TSAHC’s Home Sweet Texas and TDHCA’s My Choice Texas Home both welcome repeat buyers. Only one TDHCA program and the MCC tax credit keep a first-time rule.
• “Everything in Katy is too expensive for these limits.” Not so. Plenty of Katy homes land under the roughly $544,232 price limit, from older Old Katy neighborhoods to many sections of the big master-planned communities.

You will not know which of these applies until you confirm which county your address sits in and check your income against that county’s limit. That is a short step, and it is where most Katy buyers are surprised.

What down payment assistance in Katy actually is

Down payment assistance in Katy is help that covers your down payment and usually part of your closing costs, so you bring less cash to the table. The money comes mostly from two statewide agencies: the Texas State Affordable Housing Corporation (TSAHC) and the Texas Department of Housing and Community Affairs (TDHCA).

Each may provide up to about 5% of your loan amount, offered as a grant or a forgivable second lien, depending on the option you pick. The assistance rides on a normal first mortgage, FHA, conventional, VA, or USDA, so the underlying loan is ordinary. Our Texas down payment assistance hub covers how the statewide help works in depth.

Katy’s three counties and their local programs

Because Katy spreads across three counties, two of them offer their own down payment programs on top of the statewide help, and which one applies depends on your address:

• Harris County (the eastern Katy area, including much of Cinco Ranch) runs the Harris County Housing & Community Development down payment program, which serves unincorporated parts of the county for qualified first-time buyers.
• Fort Bend County (the southern Katy area) runs a program through the Fort Bend County Housing Finance Corporation, offering up to $10,000 to qualified first-time buyers on a first-come, first-served basis while limited funds last.
• Waller County (the northwest Katy area, growing fast around Cross Creek Ranch and Tamarron) leans on the statewide programs, with limited local funds.

To be straight with you: ShopDPA does not administer any city or county program, and these local funds are smaller and more restrictive than the statewide help. The licensed lenders in our network connect qualified Katy buyers with the TSAHC and TDHCA programs and can tell you whether a county program is worth layering in based on where your home sits.

Katy down payment assistance income limits (2026)

Income limits are measured against the area median. The figures below show approximately how high the limits may reach for non-targeted areas in the Harris and Fort Bend portions of Katy. Read them as “up to” guides; a participating lender confirms your exact number and county.

TSAHC applies one income limit at any household size, while TDHCA brackets by household. The My Choice Texas Home ceiling near $173,400 is the one that surprises Katy buyers, because it reaches well into two-income professional territory. Because the limit can shift across the county line, confirming your address is the first step in Katy.

TSAHC programs for Katy buyers

TSAHC is the program most Katy buyers end up using. TSAHC’s down payment assistance may provide up to about 5% of the loan amount, structured three ways: a no-assistance option (first mortgage plus an optional MCC, often at the lowest rate), a grant you never repay, or a three-year forgivable second lien.

• Home Sweet Texas is the general track. If your county income fits the limit, you may qualify no matter your profession or whether you have owned before.
• Homes for Texas Heroes serves teachers, police officers, firefighters, EMS, corrections officers, nursing faculty, and veterans, with the same assistance. Katy ISD staff and the city’s first responders fit here. See our Homes for Texas Heroes guide for the full occupation list.

Not every lender is approved to offer TSAHC programs, which is one reason working with a participating lender in our network matters. TSAHC also publishes its own overview for the Houston area, which covers all three Katy counties.

TDHCA programs for Katy buyers

TDHCA runs the other statewide track, and for higher-earning Katy households it is often the better fit:

• My First Texas Home is for first-time buyers (no ownership in the last three years) and qualified veterans, pairing a competitive first mortgage with assistance at the lower income limits above.
• My Choice Texas Home removes the first-time requirement and lifts the income ceiling to around $173,400, which fits repeat buyers and dual-income households better than any other program.

Both live on TDHCA’s homebuyer site. For most Katy households there is usually a fit between the two agencies; the work is picking the right one, which the eligibility step handles. Our guide to TSAHC and how it differs from TDHCA compares them in plainer terms.

The MCC tax credit for Katy buyers

A Mortgage Credit Certificate is an easy benefit for first-time Katy buyers to overlook. An MCC is a federal tax credit under IRS Form 8396 that may return up to 15% of the mortgage interest you pay each year, with no annual cap, taken straight off your federal tax bill. A credit lowers what you owe dollar for dollar, which is stronger than a deduction.

The real benefit depends on your loan amount, your rate, and your federal tax liability, so it is an “up to” figure rather than a flat promise. On a Katy-sized loan, the annual credit may add up to meaningful money, and it continues as long as you keep the loan and live in the home. TSAHC issues the MCC for qualifying first-time buyers, and our Texas MCC guide walks through the math.

How Katy DPA works with FHA, VA, USDA, and conventional loans

Assistance is not its own loan type. It rides on top of a standard first mortgage, and the right base loan depends on your credit, your cash, and what you are buying. In Katy’s mid-to-higher-priced market, conventional and FHA are both common, and each pairs with assistance differently.

The built-up parts of Katy are too urban for USDA financing, but the growing Waller County edges around Katy can sometimes qualify. Veterans have their own path: beyond a VA home loan, the Texas Veterans Land Board offers below-market loan options for Texas veterans. Our Texas VA loan guide covers the veteran path in detail.

TSAHC vs TDHCA: which Katy program fits?

The two agencies overlap, so here is how they compare at a glance for a Katy-area household.

For most Katy buyers the decision comes down to two questions: are you a first-time buyer, and where does your income sit against each limit? A participating lender can compare both on your real figures and confirm which county program, if any, layers in. Our Texas down payment assistance hub goes deeper.

Where you buy in Katy changes the picture

Katy’s three-county spread and wide range of homes mean the roughly $544,232 price limit, and your exact income limit, can shift across the area.

• Old Katy and central neighborhoods (the historic rice-milling town around Katy Mills and the older subdivisions) hold many homes well under the price limit.
• Cinco Ranch (the large master-planned community, much of it in Harris County) spans a broad price band, with plenty of homes that still fit.
• Cross Creek Ranch, Tamarron, and Firethorne (newer Fort Bend and Waller County communities on the west and south) range higher in places; a lender confirms whether a specific home qualifies and which county applies.

Buyers comparing nearby options often look at Houston and neighboring Fort Bend communities, which share closely related limits. Katy’s size and price range mean most buyers find a qualifying home inside the area.

Katy ISD and the Homes for Texas Heroes program

Nearly all of Katy is served by Katy ISD, one of the largest and most highly rated districts in Texas at roughly 95,000 students, spanning parts of all three counties. Add the energy and corporate employers along the I-10 Energy Corridor and the growing healthcare presence, and the area employs many people whose jobs qualify them for the Homes for Texas Heroes program.

Teachers, aides, counselors, librarians, and school nurses across Katy ISD qualify, as do Katy’s police officers, firefighters, and EMS. The Heroes program offers the same assistance as Home Sweet Texas, framed for your profession, with no first-time-buyer requirement. Our Texas teacher home loan guide explains how district employment verification works.

Credit score requirements for Katy DPA

Most TSAHC and TDHCA programs start around a 620 credit score. That is well short of “perfect,” and it surprises buyers who assumed assistance demanded a flawless file. Your score shapes your interest rate and which assistance option fits, but 620 is the number to aim for, and some loan types flex around it depending on the rest of your application.

If you are under 620 right now, treat it as a timeline rather than a closed door. A participating lender or a HUD-approved housing counselor can usually point to the few specific moves that may lift your score into range. A stronger score also helps your offer compete in Katy’s busier master-planned communities.

Homebuyer education for Katy buyers

Most assistance programs require a short homebuyer education course before you close. It covers budgeting, the loan process, and what to expect at closing, and buyers who take it tend to do better over the long run. You can find a HUD-approved counselor through the CFPB’s housing counselor tool, and your lender confirms which specific course your program accepts.

Recapture tax for Katy DPA buyers (IRS §143)

Some TSAHC and TDHCA bond-backed programs carry a federal recapture provision under IRS §143. A recapture tax may apply only if all three of these happen together: you sell within nine years, your income at sale is significantly above the program limits, and you realize a capital gain. If any one of those is not true, there is generally nothing to recapture.

Very few buyers ever owe it, and both agencies offer reimbursement programs that may cover a recapture tax if it is ever triggered. The mechanics live on IRS Form 8828. We mention it for honesty, not alarm; a participating lender explains how it applies to the program you choose.

Step by step: from form to closing day in Katy

1. Check where you stand. Spend a couple of minutes on the eligibility step so we understand your income, location, and goals.
2. Connect with a participating lender. We introduce you to a licensed mortgage professional in our network who is approved to offer TSAHC and TDHCA programs in the Katy area.
3. Get pre-qualified and pick your program. Your lender confirms which county your address sits in, checks your income against the limits, reviews your credit, and helps you choose the assistance option that fits.
4. Finish homebuyer education. Complete the short HUD-approved course your program requires, online or in person.
5. Shop, offer, and close. House-hunt across Katy with your assistance lined up, focus on homes inside the price limit, and bring far less cash to closing than you expected.

Documents to have ready for pre-qualification

You do not need these to begin, but they speed things up once you connect with a lender:

• Recent pay stubs (about 30 days) and the last two years of W-2s or tax returns
• Two months of bank statements
• A government-issued ID
• Your DD-214 if you are using a VA loan or the Heroes/veteran track
• A rough idea of your target Katy neighborhoods and price range
