Denver and Boulder share Colorado's clean federal conformity, but Boulder's higher entry pricing and stricter STR enforcement produce a different cost-seg profile. Denver investors building portfolio depth typically prefer the broader price-band spread and ADU expansion options Denver offers; Boulder investors are typically holding fewer higher-value properties.
Across 5 engine fixtures for the Denver area, the differences between Boulder and the rest of Denver come down to three factors: land allocation, property archetype mix, and HOA capital-assessment patterns. See the per-fixture detail below.

It depends on what "better" means.
If you measure ROI as Year-1 federal savings dollars: Boulder wins on absolute dollars (higher purchase prices = larger absolute deductions). If you measure ROI as savings-per-dollar-of-purchase: the broader Denver non-resort sub-markets typically win (lower land allocation = more depreciable basis as % of price).
For most buyers, the more useful question is: which sub-market matches my buy-box? If you're already buying $2M+ resort-tier product, the cost-seg differential is a rounding error against your decision drivers. If you're price-shopping across sub-markets and considering both, the broader Denver non-resort areas produce more reclassification per dollar.
