Most Americans are struggling with rising costs, including groceries, rent, and interest rates. As people seek affordable living options in Texas, they should avoid the state's most expensive cities. According to various sources, the five priciest cities are: 5) Plano, due to high housing costs; 4) San Antonio, with significant housing cost increases; 3) Houston, where demand drives up prices; 2) Dallas-Fort Worth Metroplex, known for high rents; and 1) Austin, the most expensive city, fueled by a tech boom and rising demand for housing.
