About 71% of active Sunday River STR listings hit the national Diamond tier (≥24% bonus-eligible depreciation) — the rest are usually one or two amenity upgrades or a lower land ratio away.

What does $1M buy in Sunday River, and how much can it save in Year-1 bonus depreciation?
Under IRS §168(k), short-term rental properties qualify for accelerated bonus depreciation on a meaningful share of the purchase price. The math below comes from a live Sunday River listing — the highest-scored active property in the market right now.
Estimate uses the score-based formula behind every DepreciMax listing card. Final cost segregation results require a property-level report — see CTA at the end of this guide.
The Structural Advantage
Why does Sunday River punch above its weight for STR bonus depreciation?
Mountain lots aren't cheap — but the structures built on them are expensive. Ski-country cabins carry premium finishes, hot tubs, wraparound decks, and thick FF&E packages that all count as depreciable improvements. In Sunday River, the median land ratio sits around 18%, well below the national residential norm — which means more of every purchase dollar flows into bonus-eligible property instead of dirt.

What Drives the Score
Which amenities are bonus-eligible in Sunday River STRs?
Prevalence of 15-year land improvements we typically see across Sunday River short-term rentals — all 100% bonus-eligible in Year 1 under IRS §168(k).
Source: DepreciMax scoring of active Sunday River STR listings. These amenities are the fastest way to spot Diamond-tier properties on tour — a home hitting 4 or more from this list is almost always ≥24% bonus-eligible.
The Non-Obvious Insight
How do Sunday River bonus depreciation scores change with price?
The top 100 ranked listings, bucketed by purchase price. The median DepreciMax Score (right column) climbs as price climbs — bigger homes carry more bonus-eligible content: pools, hot tubs, fire pits, premium finishes, FF&E.
Why this matters for the trip
The "find a cheap fixer-upper" instinct is wrong here. A $1.5M property with a pool, outdoor kitchen, and Wolf appliances can generate more Year 1 deduction in absolute dollars than three $400k properties combined. Tour every tier — but calibrate your eyes for the right signals at each one, not just the right price.
On The Tour
What should you spot on tour — and what should you skip?
The items on the left depreciate in 5 or 15 years — fully bonus eligible. The items on the right are structural — necessary for the house, but NOT bonus eligible. Outdoor amenities are the single biggest score differentiator in Sunday River.
5-Year Personal Property
Bonus Eligible- Hardwood, LVP, or stone tile flooring
- Quartz, granite, or marble countertops
- Custom cabinetry (soft-close, full-overlay)
- High-end appliances (Wolf, Sub-Zero, Thermador)
- Wine cooler / beverage center
- Decorative lighting fixtures, sconces
- Frameless glass shower enclosures
- Smart home / Lutron / Sonos
- Window treatments (motorized = strong signal)
- FF&E if conveyed (furniture, art, kitchenware)
15-Year Land Improvements
Bonus Eligible- Pool (in-ground or above-ground)
- Hot tub or spa
- Fire pit (built-in or freestanding gas)
- Outdoor kitchen / BBQ island
- Pergola, gazebo, ramada
- Outdoor fireplace or fire feature
- Paved patio or pool decking
- Mature landscaping / desert garden design
- Retaining walls, hardscape
- Exterior lighting (path, accent, security)
39-Year Structural
NOT Bonus Eligible- Foundation, framing, roof structure
- Windows and exterior doors
- Central HVAC ductwork, air handlers
- Plumbing rough-in (pipes inside walls)
- Electrical rough-in (wiring inside walls)
- Drywall, paint, embedded tile
These items still matter for condition and resale, but generate zero Year 1 deduction. A new roof doesn't help bonus depreciation — a new pool does.
Photo discipline on tour
Take 7–25 photos per property: kitchen (wide), main bath (wide), living area, primary bedroom, every outdoor amenity, and the property exterior. These are the inputs DepreciMax uses to score a property on the $99 report — so the photos you take on the tour become the depreciation analysis later.
Diligence Questions
What 5 questions should you ask the listing agent?
Each maps directly to a number that drives the Year 1 deduction. Most listing agents won't have rehearsed answers — that's fine. Ask anyway, note what they say, verify in due diligence.
-
1
What's the land value on the most recent tax assessment?
Total assessment splits into land + improvements. Lower land = higher depreciable basis = more bonus depreciation.
Sunday River context: typical answer is 14–22%. If the agent doesn't know, the Oxford County (municipal assessor: Newry) record will show it.
-
2
Is the property being sold furnished — and what FF&E is included?
Conveyed furniture, art, kitchenware, and electronics get added as 5-year personal property — often 4–8% of the purchase price in bonus depreciation.
Context: get a written FF&E list in the offer. Verbal "yes" doesn't survive closing.
-
3
How old are the HVAC, roof, and water heater — and are there receipts for recent replacements?
Recently replaced major systems can be partially classified as 5- or 15-year property if you have documentation. No receipts = no segregation.
Context: receipts also help your CPA defend the cost-seg study if it's ever questioned.
-
4
Were the outdoor amenities (pool, hot tub, fire pit, pergola) permitted — and when were they built?
Permitted improvements with a clear cost basis are easier to depreciate as 15-year land improvements. Unpermitted work creates risk for both cost seg and STR licensing.
Sunday River context: pull the parcel's permit history from the Oxford County (municipal assessor: Newry) (or the corresponding building/permit portal) before closing.
-
5
If this has been an active STR, what's the trailing 12-month gross revenue — and is there a transferable STR permit?
Permit caps and waitlists exist in many jurisdictions. A transferable permit is real value; a non-transferable one means going on the waitlist.
Sunday River context: verify with the Town of Newry / Bethel STR office, not just the agent.
Regulations Checklist
What are the short-term rental regulations in Sunday River in 2026?
Short-term rental regulations change frequently and vary by city, county, and HOA. Before you write an offer on a Sunday River STR, verify the following five items with the local STR licensing authority — not with the listing agent. Regulations that were true last year may have changed, and a mistake here can invalidate the whole investment thesis.
-
1
Is there a permit cap or moratorium?
Many popular STR markets have hit permit caps or paused new licenses entirely. Ask the Sunday River STR office directly whether new STR permits are being issued today — not "in general," today.
-
2
Is the existing STR permit transferable at closing?
In some jurisdictions, permits die with the seller and the buyer goes on a waitlist. A transferable permit is real value — sometimes 5-15% of purchase price implied in constrained markets. A non-transferable permit means potentially no revenue for months or years after closing.
-
3
Is there a primary-residence or owner-occupancy requirement?
Some cities restrict STR permits to owner-occupied properties (host lives there ≥6 months/year), which disqualifies most investor buyers. Verify whether Sunday River distinguishes owner-occupied from non-owner-occupied STR permits and which category the property qualifies for.
-
4
Are there HOA or condo association restrictions on short-term rentals?
HOA covenants can prohibit STRs even when the city permits them. Get the HOA CC&Rs in writing before closing and search for terms like "rental," "leasing," "short-term," "transient," and "minimum stay." An HOA STR ban is not fixable after closing.
-
5
What's the minimum stay length required by Sunday River?
Some jurisdictions have 30-day minimum stays that functionally kill STR use. Others require 7-day minimums, which conveniently still qualifies you for the federal STR loophole (average guest stay ≤7 days for material-participation treatment). If Sunday River imposes a minimum, verify it matches your investment thesis.
Verify with the source: DepreciMax is a software company, not a law firm. STR regulations change; the Sunday River STR office and your closing attorney are the authoritative sources. This checklist is what to ask, not what the current answers are.
