Grand Lake at a glance

Bonus depreciation (IRS §168(k)): a federal tax provision letting investors deduct 100% of qualifying property costs in the year the property is placed in service. For short-term rentals, the deductible portion is the 5-year (personal property) and 15-year (land improvements) components of the total purchase price. See what bonus depreciation is for short-term rentals for the full explainer.
Bonus-eligible %: a DepreciMax metric — the share of a property's purchase price that classifies as 5-year or 15-year property under §168(k), and is therefore 100% deductible in Year 1. Grand Lake's market-median bonus-eligible % is 23.7% — meaning a typical $824k Grand Lake STR generates ~$195k of Year-1 deduction.
The 7-day STR rule: to unlock the "STR loophole" — where bonus depreciation offsets W-2 and other ordinary income, not just passive rental income — the property must average a guest stay of 7 days or less and the owner must materially participate. See how to qualify for the STR loophole.

Colorado State Conformity — Full

Colorado fully conforms to federal §168(k). Investors capture the entire Year-1 federal deduction plus Colorado state-level tax savings against Colorado's income tax. The state layer is additive, not subtractive.

Why Grand Lake ranks #28 for STR bonus depreciation

Strongest Diamond-density STR profile in the Northeast — a third of Grand Lake short-term rentals hit ≥24% bonus-eligible % of purchase price. Cabin and lake-house amenity stack drives the 15-year improvement basis; state conformity state conformity reduces state-level benefit slightly, but federal Year 1 deduction is among the strongest on the list.

What drives Grand Lake's high bonus depreciation?

Grand Lake STRs lean heavily on the amenity categories the IRS classifies as 15-year land improvements: hot tubs, fire pits, outdoor kitchens, pergolas, and lake docks — all 100% bonus-eligible in Year 1 under §168(k). That amenity density pushes market-median bonus-eligible % to 23.7%, second only to Lake Cumberland KY (26.9%).

Does Colorado conform to federal §168(k) bonus depreciation?

Only partially. Colorado allows federal bonus depreciation to flow through, but adds back a portion at the state level and spreads it over a longer recovery period. The federal Year-1 deduction is unaffected — this is still a strong federal market — but the state portion of the savings is smaller than in fully-conforming states. PA-resident investors should model the state-federal split with their CPA before purchase.

How to use this data to underwrite a Grand Lake STR deal

The market-median numbers on this page are a screening tool, not a final answer. Here's how STR investors and their CPAs actually convert a market rank + median bonus-eligible % into an underwriting number for a specific offer.

  1. Screen the deal against the market median. If a Grand Lake listing is priced within the p25–p75 range ($512k–$1,010k) and looks like a typical cabin or lake-house STR, the market-median 23.7% bonus-eligible is a defensible screening estimate. That gives you a Year-1 deduction range you can plug into an initial underwriting model in about 60 seconds — before you invest CPA time or offer-drafting effort.
  2. Adjust up or down based on amenity signals. Grand Lake properties with a full outdoor stack (hot tub + fire pit + wraparound deck + outdoor kitchen + pergola) trend toward the Diamond tier at 24–30% bonus-eligible. Properties with minimal outdoor amenities — condos, indoor-only cabins, or properties without lake access — trend toward the Bronze tier at 18–20%. Use the amenity checklist to categorize before you commit.
  3. Model the offer with the deduction baked in. Take the estimated Year-1 deduction × your federal marginal rate (typically 37% for high-earner STR investors) = federal tax savings. Add this to your effective Year-1 cash-on-cash return. On a $824k Grand Lake STR at 23.7% bonus-eligible, that's ~$72k in federal savings — often 8–12% of purchase price flowing back into Year-1 cash. Colorado's partial conformity means state-level savings are minimal for PA residents, so pure-federal math dominates.
  4. Verify with a $99 property-level report before you sign. Once you're past screening and preparing to make an offer, run the specific property through DepreciMax's photo-analysis pipeline. The $99 report tightens the estimate to a single number, line-items the 5-year / 15-year / 39-year breakdown, and delivers a calibrated Year-1 number closely calibrated to a formal cost segregation study's bonus-eligible %. Your CPA can build the return directly from this output; a formal engineered study (typically $5,000–$8,000) is only necessary post-closing for IRS-defensible filing on very large deductions or high-scrutiny audit risk.
