Big Bear Lake is featured in the DepreciMax 2026 STR Bonus Depreciation Study — one of 197 US short-term rental markets analyzed. Big Bear sits in the San Bernardino Mountains around a 7-mile alpine lake — and crucially, its land ratios behave like a mountain market, not a coastal one.
California is decoupled from federal §168(k). Investors get the full federal Year 1 deduction on their federal return; California requires standard 27.5-year MACRS on the state return. The federal benefit is unaffected and is the larger of the two for nearly all investors. California-resident investors should model the state-federal split with their CPA before purchase.
