Talk to a Specialist →Austin and Denver both attract retirees from the Northeast, Midwest, and Pacific Coast for similar reasons: strong economies, outdoor recreation, cultural vitality, and manageable cost of living compared to coastal metros. The key differences for retirees: Texas has no income tax and Colorado has 4.4%; Texas summers are brutal and Colorado summers are exceptional; Texas Hill Country is terrain-varied but not mountainous and Colorado offers genuine Rocky Mountain access.

Denver's mile-high altitude is a consideration buyers with cardiac or pulmonary conditions should discuss with their physician before relocating. The reduced oxygen at 5,280+ feet affects exercise tolerance, particularly in the first months of adjustment. For healthy retirees, most adapt within weeks. For buyers with CHF, COPD, or significant cardiac history, altitude deserves explicit medical evaluation before choosing Denver as a retirement destination. Austin at 700 feet poses no altitude considerations.
Colorado summers are arguably the best in the country for an active retirement — dry, mild, at altitude, with mountain access. Texas winters are arguably better for retirees who want to stay active outdoors year-round — the Austin corridor rarely freezes and outdoor activity is comfortable October through April. The question is which extreme you prefer to endure: Texas summers (brutal) or Colorado winters (cold and snowy). Neither is livable outdoors at its worst; the preference is personal.
We can model the full tax picture and help you think through the lifestyle comparison.
