Talk to a Specialist →The Denver metro has 10 counties covering the 55+ market. The tax difference between the best (Douglas/Jefferson at ~0.55%) and worst (Adams at ~0.65%) is $700/year on a $700K home. Not enormous, but compounded over 20 years it matters. Here is the complete comparison with the communities in each county.
Communities: Regency at Montaine, Gleneagles Village, Sunstone Village at Terrain, Sterling Ranch Patio Villas, Rhyolite Ranch, Patios at The Meadows, Lincoln Creek, Verona, Hillside at Castle Rock, Aspendale Littleton (partial), Solstice.
Douglas County combines the metro’s best effective tax rate with Castle Rock’s outstanding lifestyle infrastructure. Philip S. Miller Park, Castle Rock’s downtown, and the Highlands Ranch master plan all sit in this county. For buyers who want quality and tax efficiency, Douglas is the answer.
Communities: Centennial at RiverWalk, Green Gables Reserve, The Villas, Valencia Condominiums, Bay Bridge, Solana Lakewood.
Jefferson County matches Douglas on rate and wins on mountain access. Lakewood is 15–20 minutes from I-70. Bear Creek Lake Park, Green Mountain, and the entire mountain corridor are accessible. Light rail W Line connects to downtown Denver. For buyers who prioritize outdoor recreation over Castle Rock’s amenity infrastructure, Jefferson is the county.
Communities: Anthem Ranch, Skyestone, Gate N Green.
Broomfield occupies the northwest Denver metro between Boulder and Denver proper. Anthem Ranch — one of Denver’s most established 55+ communities — is here. Rocky Mountain views, US-36 corridor access, and a tax rate only slightly above Douglas and Jefferson.

Communities: Heritage Eagle Bend, Hilltop at Inspiration, Reserve at Green Valley Ranch, Fairway Villas at Green Valley Ranch, Aspendale Centennial.
Arapahoe County covers the southeast metro including Aurora. Heritage Eagle Bend and Hilltop at Inspiration are here. E-470 access, Southlands, and DIA proximity make the southeast corridor convenient. The 0.05% rate gap vs Douglas adds approximately $350/year on a $700K home.
Communities: Reserve at Green Valley Ranch (partial), Fairway Villas at Green Valley Ranch (partial).
Adams County has the highest rate in the metro but the best DIA proximity — 15 minutes from northeast Aurora. For frequent fliers, this access justifies the slightly higher rate. Home prices are also generally lower in Adams County, so absolute dollar tax amounts remain competitive.
