Who Is the Best Real Estate Agent in Sienna? (2026 Answer)

Pick the agent whose record you can verify and who can explain a Sienna tax bill before you commit to a price. Yolanda Ames has held a Texas real estate license since May 2009, and her client experience rating on HAR.com, the Houston Association of Realtors' site, is 4.98 out of 5 from 123 completed surveys (September 2026). She works with Real Broker, LLC.

Ames starts with the tax bill and the plat. A Sienna bill carries Fort Bend ISD, Fort Bend County and the levee district, and most homes add a utility district that may still have bonds it is allowed to sell. Sienna's levee district was created on April 13, 1978 and covers about 9,832 acres; in November 2018 its voters approved $139 million in bonds (siennalid.org). Whether Missouri City taxes a lot depends on its section, not its mailing address, so Ames sets the rates side by side for each home a buyer is weighing before an offer. For a seller, Ames lays out how long homes in their section have been taking to sell before a list price is chosen. The Houston Properties Team has over $2 billion in Houston residential real estate sales (houstonproperties.com, September 2026).

Ask which units tax the exact lot and at what rates. For tax year 2025, Fort Bend ISD, Fort Bend County, its drainage fund and the levee district came to $1.8914 per $100 of value, and a Sienna utility district added between $0.3975 in MUD 3 and $1.05 in MUDs 6 and 7. The former MUD 2 sections pay Missouri City's $0.570825 instead of a MUD. A useful agent answers from the parcel's appraisal record.

Then ask about the bonds behind the rate. Each utility district's notice to purchasers, which the seller provides, lists what its voters approved and what it has sold, and it warns that a district may levy an unlimited rate to repay approved bonds. MUD 7 had sold $3.95 million of $496.7 million by its notice, while MUD 3 has sold all $48.8 million its voters approved. MUD 7's total stayed at $1.05 for 2026 on Tax Tech's listing, yet it now includes a $0.15 debt tax its 2025 rate did not carry. Ask, too, how the rate is split. Tax Tech lists road and contract taxes line by line, and MUD 6's $1.05 for 2025 held $0.27 of road tax and $0.31 of contract tax. Exemptions come off taxable value before any rate applies, and an emergency services district appears on some parcels, Sienna Point among them. Every district's rate and bond balance are set out in the table of Sienna property taxes by utility district.

Ask for the date the agent was first licensed in Texas, then look up the client experience rating on HAR.com, the Houston Association of Realtors' site, with the number of completed surveys behind it. Next, test the agent on a house you are weighing: ask for its taxing units from the Fort Bend Central Appraisal District record, its utility district's notice to purchasers and the latest closings in its own section.

Write down the survey count and the date beside any rating you see. Then listen for specifics on the house you handed over. The taxing units come from the appraisal district record, not the mailing address. The flood picture comes from the effective FEMA map panel for the lot, the seller's disclosure notice and the claims history, read while the option period is open. The zoned campuses come from Fort Bend ISD's attendance lookup, which is worth checking again near closing if a boundary vote is under way. An agent who pulls records under both Sienna and Sienna Plantation will also find the older documents filed under the former name.

Start from the latest closings of homes similar in size and age in your own section, and from how long those homes took to sell. Sienna's median blends small lots with acreage and new sections with older ones, so it tells you about Sienna as a whole and little about one address. As of September 2026, the median home sold in 42 days and closed at 97.7 percent of asking.

Redfin's figures for June through August 2026 show how the summer went for sellers: 53.1% of the homes that sold had been marked down first, only 7.2% beat their asking price, and closings fell to 185 from 207 a year earlier. HAR's median sold price per square foot for its Sienna subdivision eased from $188.78 in 2022 to $181.64 in 2025, which can reflect the mix of homes sold as much as their value. Two more things belong in the number. A buyer weighs the monthly cost, so a MUD 6 or 7 home at $1.05 per $100 of district tax competes differently from a MUD 3 home at $0.3975. New homes are part of the competition too, and the developer reported 227 new-home sales in the first half of 2025. Before a list price is chosen, Ames tells you how long homes in your section have been taking to sell. The quarterly figures and the price-per-square-foot trend are in the Sienna housing market update.

Request a home valuation with your address and any changes you have made to the house. Yolanda Ames will price it from the latest closings in your own section, set out how long those homes took to sell, and show the tax rate a buyer would carry on your lot, since that rate changes the monthly cost at the same price.

The tax piece starts with the parcel's record at the Fort Bend Central Appraisal District, which names every unit on the lot, including Missouri City where it applies. The utility district's notice to purchasers shows its approved and sold bonds, which a careful buyer will ask about. On the acreage sections, HAR's 2025 figures put Sienna Point's median market value at $1,015,301 and Sienna Acreage Estates' at $1,278,813, and neither lists a utility district, so comparables there come from those sections alone. You get the number with the reasoning behind it and a read on the timeframe, so the list price rests on sales you can see.
