Closing costs and property taxes in Katy, TX, can surprise buyers and sellers who are new to the Houston area. On a median priced home of $480,000, buyers typically pay between 3% and 5% of the purchase price in closing costs, or roughly $14,400 to $24,000. Sellers usually pay 6% to 8% in commissions and fees, which comes to $28,800 to $38,400. The real eye opener for many is the stacked Texas property tax bill, where multiple taxing entities each levy their own rate. Here is how it all works in Katy and what the homestead exemption saves you.
What Are Typical Buyer Closing Costs on a $480,000 Katy Home?
Buyer closing costs in Katy generally run 3% to 5% of the purchase price not including your down payment. On a $480,000 home, that means $14,400 to $24,000 in cash due at closing. These costs include the lender origination fee, appraisal, credit report, title search, title insurance, escrow fees, prepaid property taxes, and prepaid homeowners insurance. Katy ISD is rated A by the state, and many communities here sit in MUD or PID special taxing districts, which means prepaid taxes can be higher if the property is in one of those districts. Your lender will give you a Loan Estimate that itemizes every fee by law.
What Are Typical Seller Closing Costs on a $480,000 Katy Home?
Seller closing costs in Katy are dominated by the real estate commission, which is typically 5% to 6% of the sale price split between the listing and buyer agents. On $480,000, that is $24,000 to $28,800. Additional seller costs include the title policy for the buyer (about $2,000 to $3,000), a prorated share of annual property taxes, and sometimes a home warranty or repair concessions. Total seller costs usually land between 6% and 8% of the sale price, or $28,800 to $38,400. These amounts are deducted from the proceeds at closing.
How Do Texas Property Taxes Stack in Katy?
Texas property tax rates vary significantly by county and ISD, generally landing between 1.8% and 2.8% of assessed value annually. In Katy, which sits in Harris County and is served by Katy ISD, the bill stacks from multiple layers: Harris County, the City of Katy (or your applicable municipality), Katy ISD, any MUD or PID special districts your community falls under, and sometimes a community college district or a hospital district. Each entity sets its own tax rate, and you pay the sum of all of them. Because many Katy neighborhoods are in MUD or PID districts, your total rate can be on the higher end of that 1.8% to 2.8% range. On a $480,000 home, a 2.5% combined rate would mean $12,000 in annual property taxes before exemptions.
What Does the Texas Homestead Exemption Save You in Katy?
The Texas Homestead Exemption removes $140,000 from your primary residence's appraised value for school district taxes, since the 2025 tax year. In Katy ISD, where school taxes make up the largest slice of your bill, that $140,000 exemption can save you roughly $1,400 to $2,100 per year depending on the exact ISD tax rate. The exemption also caps annual appraisal increases at 10% per year as long as you maintain homestead status, which is a key protection in a growing market like Katy. To get the exemption, file with the Harris County Appraisal District by April 30 of the year following your purchase. Additional exemptions are available for owners age 65 or older and for disabled owners.
How to Budget for Closing Costs and Taxes as a Katy Buyer or Seller
If you are buying a $480,000 home in Katy, plan on bringing $14,400 to $24,000 to closing plus your down payment. Factor in annual property taxes of $9,000 to $13,500 after the homestead exemption, depending on your exact MUD or PID rates. If you are selling, expect to net about $441,600 to $451,200 after typical seller costs. Work with a local lender and a Homexa® agent who knows which MUD and PID districts apply to each property, because those can change your tax bill by thousands of dollars per year.
