Those living in the beloved Texas Hill Country may have picked the perfect long-term home: A new study ranks Fredericksburg and Burnet among the best cities to retire in Texas.

Website and financial resource SmartAsset examined three key factors to generate a “best place to retire index": income and sales taxes; the number of doctors’ offices, recreation centers, and retirement centers per 1,000 residents; and the size of the senior population.

Fredericksburg ranks No. 5 on the list, and Burnet appears at No. 10. What makes them top places for retirees to settle down? Seniors make up 30 percent of Fredericksburg's population — the highest on the list — and the tax rate of 15.3 percent is among the lowest on the list. Burnet boasts the lowest tax rate among the retirement top 10, at only 14.9 percent. Perhaps due to their remote nature, however, the cities have the fewest doctors' offices per 1,000 residents.

According to SmartAsset, the top place to retire in Texas is Katy, located just outside of Houston. The suburb leads the way in Houston-area healthcare for retirees, boasting 17.6 doctors’ offices per 1,000 residents. Four other Houston-area suburbs appear on SmartAsset’s top 10: Richmond (No. 6), Tomball (No. 7), Webster (No. 8), and Humble (No. 9).

No. 3 Woodway (near Waco) and No. 4 Livingston (located north of Houston) round out the top places in the Lone Star State to retire.
