Katy · Harris · Fort Bend · Waller
Katy is three counties, a hundred MUD districts, and one of the most sought-after school systems in Texas. Two homes at the same list price can carry very different monthly payments here — and knowing why is most of the job.
The market
Katy runs on master-planned communities — Cinco Ranch, Cross Creek Ranch, Firethorne, Elyson and dozens more — and on the school district that draws families from across the Houston metro. Katy ISD's reputation is the single largest force in this market, and it drives demand hard enough that district boundaries, not city limits, often determine what a house is worth.
The financing wrinkle here is unusually important: Katy is among the most MUD-heavy markets in Texas. Almost every master-planned community sits inside a municipal utility district that levies its own tax to repay the water, sewer, and drainage infrastructure that made the neighborhood possible. Those rates vary substantially between districts, and they flow straight into your escrow. Two identical homes at the same price, a mile apart, can differ by hundreds of dollars a month purely on district rate.
Employment leans heavily on the Energy Corridor along I-10 — oil and gas majors, engineering firms, and the consultants and contractors who orbit them. That means a lot of bonus income, some equity compensation, and a meaningful share of self-employed professionals whose tax returns understate what they actually earn. Matching that income to the right documentation path is a regular part of Katy files.

The fine print, locally
This market has three diligence items that matter more than almost anywhere in Texas. Get these right and the rest of the transaction is ordinary.
Almost every Katy community sits in a municipal utility district with its own tax rate, and those rates differ meaningfully district to district. A newer district that recently issued bonds often carries a higher rate than an older one that has paid its infrastructure down. Compare total tax rates, not list prices — this is the single biggest payment swing in Katy.
Some neighborhoods on Katy's east side sit within or near the Barker Reservoir flood pool. Hurricane Harvey made this unmistakable when reservoir management flooded homes that were not in conventional flood zones. Ask directly whether a property is in a reservoir pool — it is a distinct question from the standard flood zone determination, and it belongs at the front of your diligence.
Separate from the reservoir issue, every mortgage includes a flood zone determination, and a property in a designated special flood hazard area requires flood insurance. In this metro that cost is material enough to change what you can afford, so establish it early rather than late.
Katy straddles Harris, Fort Bend, and Waller counties. County, city, school, and MUD levies stack differently depending on which side of a line a home sits, and FHA loan limits are set by county as well. The mailing address says Katy; the tax bill says which county.
The district extends well beyond the city of Katy, and boundaries shift as the district grows and opens campuses. Confirm the assigned schools for a specific address rather than assuming from the city name — buyers pay real premiums for particular attendance zones.
With this much new construction, builders regularly offer rate buydowns and closing-cost credits through preferred lenders. Sometimes those are genuinely excellent. Sometimes an independent quote beats them. Comparing costs you nothing, and we will tell you honestly if the builder wins.

Two layers stack up. Texas funds local services through property taxes rather than income tax, and on top of that nearly every Katy master-planned community sits in a municipal utility district that levies an additional tax to repay water, sewer, and drainage infrastructure. MUD rates vary considerably between districts, so we verify the actual total rate for a specific address — it can swing your monthly payment by hundreds of dollars.
A municipal utility district is a special district that issues bonds to build a community's water, sewer, and drainage systems, then levies a property tax to repay them. Rates differ by district and generally decline over time as the debt is paid down, which is why a newer neighborhood often carries a higher MUD rate than an established one nearby. Since it flows into your escrow, we always confirm the district and rate before you're deep into an offer.
It depends on the exact location, and it's worth asking explicitly — this is a separate question from the standard FEMA flood zone determination every mortgage includes. Some neighborhoods on Katy's east side lie within or near the reservoir flood pool, an issue Hurricane Harvey brought into sharp focus when reservoir management flooded homes outside conventional flood zones. Raise it early in your diligence, not at the end.
All three, depending on the address — Katy spans Harris, Fort Bend, and Waller counties. That matters because county, school, and district tax rates stack differently on either side of those lines, and FHA loan limits are set by county. The city on your mail doesn't tell you which tax jurisdiction you're in.
Usually yes, with the right documentation. Bonus and incentive income can count toward qualifying when the history supports it, and equity compensation can too. If you're a consultant or contractor whose returns are write-off-heavy, a bank statement loan qualifies you on 12 to 24 months of actual deposits instead. Both are common in Katy files — the key is structuring it before you write an offer.
Compare, don't assume. Builder incentives like rate buydowns and closing-cost credits can be genuinely valuable, and in some cases they're the better deal. In others an independent quote wins. Getting a second quote costs you nothing, and we'll tell you straight if the builder's offer is stronger.
