A home loan in Missouri City, TX is a residential mortgage in a Fort Bend County city that also extends into Harris County, and whose two largest master-planned communities — Sienna and Riverstone — sit largely outside the city limits in its extraterritorial jurisdiction. Whether your address is inside the city, in the ETJ, or scheduled for annexation determines your tax stack, and it is not something a listing will tell you.
Key Takeaways for Missouri City Buyers
- The core Missouri City ZIP closed 1,186 single-family homes in 2025 at a median near $410,000 — more volume than either Pearland ZIP and a higher median.
- Sienna is not in Sugar Land. It is a separate community in Fort Bend County with a Missouri City association, served by Fort Bend ISD.
- Sienna’s each phase has its own MUD, and older phases carry less remaining bond debt than newer ones. Combined rates commonly run in the 2.5% to 3%-plus range.
- Annexation is actively underway. Sienna MUD 2 has been annexed by the City of Missouri City, and further annexation has long been contemplated as the community approaches full buildout.
- Riverstone straddles two cities. Its 3,700 acres sit mostly in unincorporated ETJ of both Sugar Land and Missouri City, with strips inside each city proper. Two neighbors can have different city lines on their tax bills.
- Missouri City itself spans Fort Bend and Harris counties, so the appraisal district follows the address, not the city name.
What Does the Missouri City Market Look Like Right Now?
Substantial and split. The Sienna and Riverstone side of the market carries both the volume and the price; the older northern sections and the Fresno area behave very differently.

About this figure. Closing counts and median prices come from MLS records that update on a rolling basis, and recent months can revise upward as late closings post. Treat these as approximate and current as of the last available data.
Volume in 77459 exceeds Sugar Land’s entire city total, and the median sits above several other suburbs on this side of the metro. If you have been treating Missouri City as Sugar Land’s smaller neighbor, the transaction data does not support that framing.
The three-ZIP spread also tells you where the market is concentrated. Roughly two-thirds of all activity happens in 77459, and that is where the price support lives. The northern ZIP and the Fresno area serve a genuinely different buyer at a genuinely different price point — useful if you are trying to get into Fort Bend ISD without a Sienna budget, but a different conversation entirely from the one most Missouri City buyers are having.
City Limits, ETJ, and Why It Changes Your Payment
Texas cities have an extraterritorial jurisdiction — an unincorporated ring outside the city limits where the city holds certain planning authority but does not provide full services and does not levy its city property tax. Both of Missouri City’s marquee communities developed largely inside ETJ rather than inside the city.
That produces three possible tax profiles for homes that all look identical from the street. A home inside the city limits pays the Missouri City rate on top of county, school and any district taxes. A home in the ETJ pays no city rate but typically carries a MUD, and sometimes a levee improvement district or a public improvement district as well. A home scheduled for annexation is somewhere in between, and its stack is going to change.
This is not hypothetical. Sienna MUD 2 has been annexed by the City of Missouri City, and annexation of Sienna has been contemplated for years, tied to the community reaching substantial buildout and the city assuming the outstanding development debt. For a buyer, the practical question is which side of that transition your specific section is on, and what the stack looks like afterward.
The document that answers it
The title commitment lists every taxing district attached to the property, and the MUD certificate obtained through title during your option period gives the current rate. Between them you get the real answer — not the community’s marketing rate, not a neighbor’s bill from a different phase. Send both to us and we will build your escrow from them.

LET’S TALKBuying in Sienna
Sienna covers roughly fourteen square miles southeast of Sugar Land along Highway 6, served by Fort Bend ISD with multiple campuses on site including Ridge Point High School. It is the largest active master plan in this part of the county and the reason 77459 carries the volume it does.
Three financing realities worth knowing before you tour a model:
- Every phase has its own MUD. Older phases have retired more bond debt than newer ones, so an established section can carry a meaningfully lower rate than a brand-new one across the street. Combined rateshere have commonly been reported between roughly 2.5% and just over 3%.
*
About this figure. Tax rates are set separately by counties, cities, school districts and utility districts, and each adopts and publishes on its own calendar. Rates and assessed values are approximate, reflect the most recent published figures available, and should be confirmed for a specific address. - Sienna is not Sugar Land. Same county, same Fort Bend ISD draw, minutes apart — but a different city relationship and a different tax stack. Buyers comparing a Sienna home against a Sugar Land home on price alone are comparing two different monthly costs.
- Levee districts exist here too. Fort Bend levee improvement districts appear on some bills in this part of the county alongside the MUD. Read the full list on the title commitment.
None of this is a reason to avoid Sienna. The amenities, the schools and the scale are exactly what buyers come for. It is a reason to model the payment on the specific section rather than the community average — a difference that in this market runs to real money every month for as long as you own the house.
Riverstone: One Community, Two Cities
Riverstone is roughly 3,700 acres planned for about 6,000 homes, and it is the clearest example in Fort Bend County of why the address on the mailbox is not the answer to the tax question. The community is largely unincorporated, sitting in the extraterritorial jurisdictions of both Sugar Land and Missouri City, with strips of land actually inside each city proper.
In practice, Riverstone contains homes with Sugar Land addresses and homes with Missouri City addresses, and the neighborhood-by-neighborhood breakdown does not follow an intuitive line. Much of the earlier development fell in the Missouri City ETJ, while the majority of the total land area and most future homes sit on the Sugar Land ETJ side.
If you are shopping Riverstone, ask three questions in writing: which city is on the tax bill, whether the property is inside city limits or in ETJ, and which MUD or levee district applies. Buyers routinely assume they are purchasing a Sugar Land home and discover otherwise at closing — usually harmless, occasionally a several-hundred-dollar monthly surprise.
Which Missouri City Communities Do We Finance?
From 1970s golf-course neighborhoods to the newest Sienna sections — a fifty-year spread of housing stock in one city.
Sienna
The county’s largest active master plan, with on-site Fort Bend ISD campuses, a country club, and Camp Sienna. Phase-by-phase MUDs and ongoing annexation make the section the deciding detail.
Riverstone
Lake-oriented upper-tier housing split across two cities’ jurisdictions. Confirm which city, and whether city limits or ETJ, before you compare payments.
Quail Valley
The original Missouri City golf community, established and inside city limits. Mature trees, larger lots, and older housing where inspection and roof age drive the file.
Lake Olympia & Colony Lakes
Water-oriented established communities in the middle of the price range, with settled districts and steady turnover.
Vicksburg
Established housing on the Highway 6 corridor, generally more accessible pricing with a mix of district structures worth confirming individually.
Fresno & the 77545 Area
Southeast of the city at a lower price band, largely unincorporated. The most common entry point in this market and where FHA files concentrate.
Which Loan Programs Fit Missouri City?
The price spread here — from the $240,000s in the north to well over $500,000 in Sienna and Riverstone — means the program mix is unusually wide, and Fort Bend ISD demand supports value across all of it.
To model a payment, use the mortgage calculator with the combined rate for that specific section rather than a city average.
How Should You Approach a Missouri City Purchase?
- Ask which city is on the tax bill. In Riverstone especially, the mailing address does not answer this.
- Establish city limits or ETJ. It determines whether a city rate applies at all, and what services you receive.
- Get the title commitment and read the district list. MUD, levee improvement district, public improvement district — some properties carry more than one.
- In Sienna, confirm the phase. Each has its own MUD and its own remaining bond debt.
- Ask about annexation status. If your section is in line for annexation, the tax stack is going to change.
- Pull the flood determination. The Brazos and Oyster Creek both influence this part of Fort Bend County, and elevation varies.
- Let multiple lenders compete for the file. We shop it and show you the options side by side.
If You Already Own Here
Quail Valley, Lake Olympia and the older Highway 6 neighborhoods have deep owner tenure and substantial accumulated equity. Texas caps homestead borrowing at 80% combined loan-to-value across all liens, with a 12-day waiting period from application and a three-day right of cancellation after closing — state constitutional rules rather than lender policy.
And the rule that catches people: VA and FHA cash-out refinances are not available on a Texas homestead. Those files run as conventional Section 50(a)(6) loans instead. Worth a second opinion if you have been told otherwise.
Missouri City Home Loan Questions
＋ Is Sienna in Sugar Land?
No. Sienna is a separate community in Fort Bend County southeast of Sugar Land, associated with Missouri City and served by Fort Bend ISD. Same county and same school district draw, but a different city relationship and a different tax stack.
＋ What is an ETJ, and why does it matter to my mortgage?
An extraterritorial jurisdiction is the unincorporated ring outside a city’s limits where the city holds some planning authority but does not levy its city property tax or provide full services. A home in ETJ typically pays no city rate but carries a MUD instead, which changes your escrow and your qualifying ratios.
＋ Is Riverstone in Sugar Land or Missouri City?
Both, depending on the section. Riverstone is largely unincorporated, sitting in the extraterritorial jurisdictions of both cities with strips inside each city proper. It contains homes with Sugar Land addresses and homes with Missouri City addresses, so confirm the taxing city by address.
＋ Why are Sienna property taxes higher than in older neighborhoods?
Because newer master-planned communities carry MUD bonds that funded the roads, utilities and amenities, repaid through your tax bill. Each Sienna phase has its own district, and older phases have retired more of that debt than newer ones, so rates vary within the community.
＋ What happens to my taxes if my section gets annexed?
The stack changes. Annexation typically brings the city property tax rate and city services, while the utility district’s role and debt are addressed as part of the process. Sienna MUD 2 has already been annexed by the City of Missouri City. Ask specifically about annexation status for the section you are considering.
＋ Which county is Missouri City in?
Primarily Fort Bend, with a portion extending into Harris County. That determines which appraisal district values your home, where you file your homestead exemption, and which county rates appear on your bill.
＋ What is a levee improvement district?
A district that funds levee and drainage infrastructure, common in parts of Fort Bend County near the Brazos. It appears as a separate line on your tax bill alongside any MUD. The title commitment lists every district attached to the property.
＋ Is Missouri City served by Fort Bend ISD?
Most of it is, including Sienna and Riverstone, and Fort Bend ISD is among the strongest large districts in Texas. As always, confirm campus assignment by exact address, since zoning can vary by section and districts rezone as they grow.
＋ Can I get preapproved without a credit pull?
We can review your scenario, structure the file and discuss options before pulling credit. A formal preapproval that a builder or seller will rely on does require a credit report, but the exploratory work does not.
