Texas does not have a state income tax, which means it relies on property taxes to fill that gap. Many Korean families looking for their first home in San Antonio are often surprised by the property tax bill that arrives after closing. The effective property tax rate in Bexar County is typically around 2.0%, which is more than double the national average of about 0.9%.

When you do the math, the impact becomes clear. If we consider the median home price in San Antonio to be about $270,000 and apply the effective tax rate of 2.05%, the annual property tax comes out to roughly $5,500. This translates to about $460 that needs to be set aside each month. In areas with good school districts or new developments, an additional school district tax (ISD) may apply, increasing the actual burden.

Insurance costs are also significant. The South Central Texas region, including San Antonio, is known as a 'hail zone' due to frequent hail damage, leading to a high number of roof damage claims. In recent years, it has not been uncommon for annual homeowners insurance premiums to exceed $3,000, with a realistic expectation of averaging between $2,800 and $3,500.

Maintenance costs are typically estimated at about 1% to 1.5% of the home price. For a $270,000 home, it would be safe to budget around $2,700 to $4,000 annually, with a median of about $3,000. Older homes may incur higher repair costs for air conditioning, roofing, and foundation work, so it's wise to lean towards the higher end of that range.

Adding these three costs together, the total annual ownership cost comes to approximately $11,700, or about $970 per month, including property tax of around $5,500, insurance of about $3,200, and maintenance of about $3,000. It's important to calculate this fixed cost in addition to the mortgage principal and interest before purchasing, as it helps with cash flow management.

Compared to nearby counties, Bexar County's burden is not particularly high. Travis County, where Austin is located, often has a tax rate around 2.2%, while the adjacent Comal County tends to be lower at around 1.8%. Even within the San Antonio metropolitan area, tax rates can vary significantly depending on school districts and city boundaries.

Texas has a well-established homestead exemption program, so if it's your primary residence, you should definitely apply. There is a provision that allows a $100,000 deduction from the taxable value for school district taxes, and a cap that limits the annual increase in assessed value to 10% is also in place. Additional exemptions may be available for those over 65 or with disabilities, so it's advisable to check the eligibility requirements on the county appraisal district's website.

Every spring, the Bexar County Appraisal District sends out new assessment notices, and the deadline for filing a protest is usually around May 15. Submitting documentation based on recent sales in the area can lead to a downward adjustment of the assessed value, so it's practical to handle both the exemption application and the protest process in the first year for potential tax savings. For newly built homes, it's common to start with a low assessed value in the first year, which can then be significantly increased the following year upon completion, so it's important to consider that when budgeting, as unexpected increases may occur.

Ultimately, while the purchase prices in San Antonio are generally lower than the average in major U.S. cities, the actual cost of ownership, considering taxes and insurance, is not insignificant. Before making an offer, I recommend checking the recent assessed value and tax rate for the property on the county website, and obtaining insurance quotes from two or three providers to calculate the total ownership costs. Especially when taxes and insurance are paid through an escrow account, it's common for insurance premiums to rise at renewal times, leading to unexpected increases in monthly payments, so it's a good practice to carefully review the renewal notices each year.
