1. Donnelly Market Overview
⚠️ This is a Vacation Rental Market, Not a Long-Term Rental Market: Donnelly has a permanent population of approximately 200 people and very limited long-term rental demand. This guide is fundamentally different from the Boise Metro and North Idaho guides in this series. Donnelly investment is primarily about short-term vacation rental income from Tamarack Resort ski season and Lake Cascade summer season. Investors who need a tenant to sign an 18-month lease and pay $2,000/month consistently will not find that product in Donnelly. Investors who want Mountain West ski and lake vacation rental exposure at the most affordable prices in the McCall corridor should read on.
Market Fundamentals
Donnelly is a small Valley County community located on Highway 55 approximately 15 miles south of McCall and 95 miles north of Boise. Despite its small permanent population, Donnelly sits at the convergence of three major recreational demand drivers: Tamarack Resort to the west, Lake Cascade to the south, and the broader McCall-Payette Lakes recreational corridor to the north. This positioning makes Donnelly one of Idaho’s most interesting vacation rental investment locations: a genuine Mountain West ski and lake market at prices that are achievable for investors who cannot access Sun Valley, Sandpoint, or McCall proper.
Key fundamentals:
- Tamarack Resort: Idaho’s most developed ski resort outside Sun Valley, located 3-5 miles from downtown Donnelly; ski-in/ski-out condos available
- Lake Cascade: 28,000-acre recreational reservoir immediately south; boating, fishing, paddleboarding
- Distance to Boise Metro: 95 miles via Highway 55, approximately 1.5 hours; primary feeder market
- Distance to McCall: 15 miles north; Donnelly provides more affordable McCall corridor access
- No STR Restrictions: Valley County and Donnelly have no STR ordinances (as of 2026)
- Low Inventory: Very few properties available at any given time; thin market with negotiating complexity
- Dual Season: Ski winter (December-March) and lake summer (June-August) provide two distinct demand peaks
Donnelly sits at the junction of Tamarack Resort and Lake Cascade in Valley County’s McCall recreational corridor
Tamarack Resort Status (2026)
- Operations: Ski resort actively operating with multiple lifts and terrain
- Summer programming: Mountain biking, hiking, disc golf, gondola rides
- Village development: Ski village with lodging and commercial amenities in progressive development
- Trajectory: Ongoing investment expanding amenity base and visitor capacity
- Investment implication: Each Tamarack expansion increases Donnelly STR demand and rates; verify current resort status directly before investing
Donnelly vs. McCall: The Vacation Rental Comparison
| Factor | Donnelly | McCall | Investor Implication |
|---|---|---|---|
| Entry Price (3BR) | $380K-$550K | $650K-$1.5M+ | Donnelly requires 40-60% less capital for comparable recreation exposure |
| Ski Resort | Tamarack (5 mi) | Brundage Mtn (8 mi) | Tamarack is actually closer to Donnelly than Brundage is to McCall downtown |
| Lake Access | Lake Cascade (adjacent) | Payette Lake (waterfront) | Payette Lake is more scenic; Lake Cascade is excellent but different character |
| Town Amenities | Very limited; general store level | Established resort town; full restaurants, retail | McCall’s amenity advantage is real; Donnelly guests drive to McCall or eat in |
| STR Gross Revenue (3BR) | $30K-$45K/year | $40K-$70K/year | McCall earns more per property but on a much higher purchase price |
| STR Yield on Price | 7-10% | 5-7% | Donnelly outperforms McCall on gross yield; more revenue per dollar invested |
The comparison shows Donnelly’s core investment advantage: not better absolute income than McCall, but better income per dollar invested. A Donnelly investor who spends $450,000 earns 7 to 10% gross STR yield. A McCall investor who spends $850,000 earns 5 to 7% gross yield on the same income stream. Donnelly is the efficient capital deployment option in the McCall corridor for investors who want ski and lake vacation rental income without committing McCall-level capital.
Investment Strengths
- Tamarack Resort provides genuine ski season demand that grows with resort investment
- Lake Cascade ensures summer demand independent of ski season
- No STR restrictions; Valley County’s permissive STR environment
- Most affordable entry in McCall corridor; lowest capital requirement
- McCall’s rising prices increasingly drive overflow to Donnelly STR market
- 1.5 hours from Boise Metro’s 700,000+ population; huge accessible feeder market
Honest Limitations

- Deep shoulder season (April-May, October-November) revenue near zero
- Very few local services for guests; Donnelly has minimal dining and retail
- Property management is challenging; few professional STR managers serve Donnelly
- Very thin inventory; finding the right property takes patience
- STR revenue highly variable depending on property quality, location, and management

Primary Investment Zones
Expert Insight: “The Donnelly STR market has matured significantly since Tamarack reopened under its current ownership. The guests are different now: they are not just Boise families looking for a cheap cabin; they are ski families who have done Sun Valley, done Brundage, and found that Tamarack gives them a more affordable and less crowded mountain experience. Those guests book early, they book long, and they come back year after year. The investors who recognized Tamarack’s potential in 2015 are looking at properties that have doubled in value. The question now is whether Tamarack continues to expand its terrain and village, because that is what drives the next phase of appreciation.” – Kristin Walsh, Valley County Vacation Property Group
3. Property Types
Tamarack Village Condos (Ski Premium)
Condominiums within or immediately adjacent to Tamarack’s ski village. True ski-in/ski-out units are rare and highly valued. Village units have the highest winter occupancy and rates of any Donnelly property type. Multiple HOA layers with Tamarack village HOA and building HOA fees. Verify rental policies before purchasing any Tamarack village unit.
SFH with Tamarack Access (Best Value)
Stand-alone homes within a few miles of Tamarack with no HOA complications. Usually 3 to 4 bedrooms, able to accommodate ski groups of 6 to 10. Better revenue per bedroom than condos due to group bookings. Simpler management structure. Typically $380,000 to $530,000 with full STR flexibility.
Lake Cascade Waterfront Cabins
Lakefront or lake-access properties with dock or beach rights. Summer peak performance rivals or exceeds Tamarack properties during July and August. Boise families book these a year in advance for holiday and peak weeks. Off-season revenue is lower without the ski market, but lakefront values hold well due to scarcity.
Budget Cabin / Townsite Value
Older cabins and homes in Donnelly’s original townsite at $310,000 to $430,000. Lower STR revenue than Tamarack or lakefront zones but much lower entry cost. Works for investors who want Valley County vacation rental exposure at minimal capital. Some need renovation to meet Airbnb/VRBO quality standards for competitive rates.
Dual-Use / Owner-STR Hybrid
Many Donnelly investors use their property personally 30 to 60 days per year while renting it the remainder. This hybrid approach reduces annual STR revenue but provides personal enjoyment of the McCall corridor’s recreational amenities. A family that uses the property 45 days/year can still generate $25,000 to $40,000 in STR revenue depending on zone and management quality.
Large Group / Event Venue
Properties that accommodate 10 to 16 guests command the highest per-night rates in the Valley County STR market. Large family reunions, ski trip groups, corporate retreats, and wedding parties book large Valley County properties at $500 to $800+/night during peak periods. Requires more management intensity but delivers the highest absolute revenue.

Full P&L Analysis: 3BR Tamarack-Adjacent SFH at $450,000
| Item | Monthly Avg | Annual | Notes |
|---|---|---|---|
| Gross STR Revenue | $3,289 | $39,472 | Before all fees and operating costs |
| STR Management Fee (25%) | -$822 | -$9,868 | Valley County co-hosting typically 20-28%; use 25% for conservative model |
| Airbnb/VRBO Platform Fees (3%) | -$99 | -$1,184 | Host-side fees on platforms |
| Cleaning and Supplies | -$300 | -$3,600 | Professional cleaning between each stay; supplies restocking |
| Utilities (host-paid) | -$220 | -$2,640 | Electric, gas, internet, water; year-round host responsibility |
| Property Taxes | -$218 | -$2,610 | Valley County ~0.65% of $402K assessed |
| STR Insurance | -$175 | -$2,100 | STR-specific commercial landlord policy; higher than standard landlord insurance |
| Maintenance + CapEx (6%) | -$198 | -$2,368 | Higher turnover frequency means more wear than LTR; 6% appropriate |
| Net STR Income | $1,257 | $15,102 | Before mortgage; STR cap rate 3.36% on $450K |
| Mortgage ($450K, 25% down, 6.75%, 30yr) | -$2,523 | -$30,278 | $337,500 loan at 6.75% |
| CASH FLOW | -$1,266 | -$15,176 | Negative carry; total return through appreciation required |
| Total Return (9% appreciation) | ~22% | $40.5K equity – $15.2K carry = $25.3K net on $112.5K invested | |
| Upside Case (great management) | STR gross $52K, carry -$5K | Best-managed Tamarack properties significantly outperform the model above |
The P&L shows a modestly negative carry of -$1,266/month with total return of approximately 22% at 9% appreciation. The wide range of outcomes is critical to understand: a poorly managed Donnelly STR might generate only $20,000 gross (halving the revenue assumptions), making the carry deeply negative. An expertly managed property with professional photography, dynamic pricing, and superior guest experience might generate $50,000 to $55,000 gross, reducing the carry to near neutral. Management quality variance is larger in STR markets than in long-term rental markets. This is not a passive income strategy; it is an active one.
Valley County Transient Occupancy Tax: Idaho does not have a statewide short-term rental tax, but Valley County and some municipalities collect a transient occupancy tax (room tax) on short-term rentals. Verify the current applicable tax rate with Valley County before projecting net STR income. Airbnb and VRBO typically collect and remit this tax on the host’s behalf in Idaho, but confirm this directly with your PM or accountant before relying on it. Transient occupancy taxes of 3 to 8% effectively reduce your gross revenue by that percentage.
5. Legal Framework
✅ Valley County: No STR Restrictions, Full Idaho State Landlord Law
Valley County and the City of Donnelly have no short-term rental ordinances, registration requirements, or density caps as of 2026. This is one of Idaho’s most permissive STR environments. Idaho Code Title 55 statewide law applies for any long-term rental component. STR operators in Donnelly have near-complete operational freedom, limited only by any HOA restrictions on the specific property and applicable transient occupancy tax obligations.
STR Legal Environment
- No STR Permits: Valley County requires no STR operating license or permit as of 2026. Verify directly with Valley County Planning and Zoning before investing, as STR regulations can change.
- No STR Density Caps: No limit on how many STRs can operate in a given area. Unlike some Idaho resort areas, Donnelly has not implemented STR quota systems.
- No Minimum Stay Requirements: No city or county ordinance requires minimum nights. Operators can rent for 1-night stays.
- Transient Occupancy Tax: Verify current Valley County room tax rate and collection mechanism before projecting net revenue.
- Fire and Safety: Idaho State Fire Marshal requirements for short-term rentals may apply; smoke detectors, CO detectors, and fire extinguishers are standard requirements.
HOA Considerations (Critical for Tamarack)
The Tamarack Resort village and many Donnelly area developments have HOA and resort association structures. These can significantly restrict STR operations:
- Tamarack HOA/Association: Tamarack resort area properties may be subject to Tamarack Owners Association rules, which could include STR restrictions, rental pool requirements, or mandatory management company usage
- Rental Pool Programs: Some Tamarack village condos are enrolled in or restricted to Tamarack’s own rental management program; confirm whether this is mandatory and at what fee level
- Building HOAs: Individual condominium buildings within Tamarack village have separate building HOAs with their own rules; request and review both the resort association CC&Rs and the building HOA CC&Rs
- SFH Outside Resort: Stand-alone homes outside Tamarack’s formal development typically have no HOA restrictions; this is the preferred structure for maximum STR flexibility
6. Donnelly Investment Playbook
Define Your Donnelly Strategy
Pure STR Investment
Maximum rental availability; professional management; dynamic pricing; high-quality photography. Target $35,000-$50,000+ gross annually near Tamarack. Accept negative carry of $500-$1,200/month offset partially by STR income.
Personal Use + STR Hybrid
Personal use 30-60 days/year (ski trips, lake weekends); rent the remainder. Lower total STR revenue but personal enjoyment subsidizes some of the carry. Most popular structure for Boise Metro buyers.
Build Your Donnelly Team
- STR Property Manager / Co-Host: The most important relationship in Donnelly. Finding a qualified STR manager who actively manages Tamarack and Valley County properties is harder than in larger markets. Ask for their current AirDNA data on comparable managed properties. A good STR manager can double your revenue relative to self-management with mediocre photos and basic pricing.
- Valley County Real Estate Agent: Very few agents specialize in Valley County investment property. An agent with McCall and Donnelly transaction history, specifically in vacation property sales rather than primary residential, understands the STR value drivers that differ from conventional appraisal methodology.
- STR Lender (Vacation Home Financing): Conventional investment loans on Donnelly properties can be complicated by the vacation/resort character. Some lenders require vacation home financing rather than investment property financing if personal use is planned. Others offer DSCR products using projected STR income. Research your loan structure before committing.
- Idaho CPA with STR Experience: Short-term rental taxation is genuinely complex, particularly the personal use/rental use split, material participation rules for STR loss deductions, and transient occupancy tax obligations. An Idaho CPA who specifically serves resort property clients is not optional; it is necessary.
Donnelly-Specific Due Diligence
STR and Property Checks
- Pull AirDNA or Mashvisor comp data for the specific Donnelly zone before buying; actual STR revenue for comparable properties vs. theoretical projections
- Tamarack Resort operating status: verify current lift operations, village amenity status, and expansion timeline directly with resort management
- HOA rental policy (critical): mandatory rental pools, Tamarack management requirements, STR prohibitions, owner use day limits
- Well and septic status for any rural Valley County property; both are common outside Donnelly townsite
- Winter access: confirm year-round road access and snow clearance responsibility for rural properties
Revenue Verification
- Request actual prior-year STR revenue statements from any property being sold as a producing STR; never rely on forward projections alone
- Check the listing’s existing Airbnb/VRBO history if available; reviews, response times, and pricing history reveal management quality
- Verify seasonal rate patterns against actual Tamarack snowfall data; poor snow years significantly reduce winter STR revenue
- Valley County room tax compliance: confirm whether the seller has been current on transient occupancy tax obligations
Optimize Your Donnelly STR
- Professional Photography: In a market as small as Donnelly, professional photography is the single highest-ROI investment after the property itself. A $500 professional shoot on a $450,000 property that generates $3,000 more per year than mediocre photos returns 600% annually on that photography investment.
- Dynamic Pricing Software: PriceLabs, Wheelhouse, or Beyond Pricing tools automatically adjust your nightly rate based on local demand signals, Tamarack events, and competitive inventory. Manual pricing for a Donnelly STR leaves significant revenue on the table.
- Ski Season Booking Calendar: Open your ski season dates 6 to 9 months in advance. Ski groups, especially those booking holiday week rentals (Christmas, Presidents’ Day, MLK), plan far in advance and pay peak rates. Late-opening your booking calendar misses these high-value reservations.
- Winter Sports Amenities: Boot dryers, ski storage, hot tub, high-speed internet, and a well-stocked kitchen convert one-time ski visitors into annual repeat guests. Guest loyalty is the single most efficient revenue driver for rural mountain STR properties where marketing reach is limited.
7. Financing Options for Donnelly
| Loan Type | Down Payment | Rate | Best For | Donnelly Note |
|---|---|---|---|---|
| Vacation Home Loan | 10-15% | Slightly above primary; below investment rate | Personal use + STR hybrid; lower down payment | If you intend personal use, vacation home financing requires only 10-15% down vs 25% for investment property. Lower rate too. Requires bona fide personal use intent and is subject to occupancy requirements. |
| Conventional Investment | 25% | +0.5-0.75% | Pure STR investment, no personal use | Standard approach. Donnelly properties within conforming limits for most SFH. Tamarack condos may require condominium project approval from lender. |
| DSCR (STR Revenue) | 20-25% | +1.5-2.5% | Self-employed; can use projected STR income | Some DSCR lenders use AirDNA market data for STR income qualification instead of lease. This can work for Donnelly’s STR-heavy market where conventional income documentation misses the actual revenue picture. Shop multiple lenders on this. |
| Portfolio / Vacation Home | 20-25% | +1-2% | Valley County rural or non-warrantable condos | Some Tamarack condos or rural Valley County properties may be non-warrantable; Idaho Central Credit Union and local community banks can hold these in portfolio. |
Vacation Home Loan Strategy: If you plan any personal use of a Donnelly property, vacation home financing at 10 to 15% down can dramatically reduce your entry capital versus a 25% investment property loan. On a $450,000 Donnelly property, the difference is $45,000 to $67,500 in down payment. The lower rate also reduces monthly carry. The trade-off is that true intent for personal use must exist; using a vacation home loan on a property you never personally visit creates mortgage fraud risk. Talk to your lender clearly about your actual use plans before choosing your loan structure, and work with an Idaho CPA on the tax implications of vacation vs. investment property classification. The IRS 14-day/10% rule determines whether your property is treated as a rental (deductible losses) or vacation home (limited deductibility) for federal tax purposes.
8. Frequently Asked Questions
Knowledge Quiz: Donnelly Idaho Vacation Rental Investment
Open Quiz
5 quick questions on Donnelly STR investing and the Tamarack/Lake Cascade market
1) What makes Donnelly’s STR market fundamentally different from all the other Idaho markets covered in this guide series?
Answer: C
Every other market in this Idaho guide series is primarily a long-term rental market where the investment thesis centers on workforce or family housing demand. Donnelly is different: with ~200 permanent residents, there is essentially no long-term rental market. The entire investment case rests on STR income from Tamarack Resort’s ski season and Lake Cascade’s summer recreation season. Investors looking for a tenant to sign a 12-month lease at $2,000/month will not find that product in Donnelly.
2) What is Donnelly’s primary advantage over McCall for vacation rental investment?
Answer: B
The guide’s comparison table shows that while McCall properties generate more absolute STR revenue ($40K-$70K/year gross vs. Donnelly’s $30K-$45K), McCall requires $650K-$1.5M+ in capital vs. Donnelly’s $380K-$550K. On a yield basis, Donnelly outperforms McCall at 7-10% gross vs. 5-7%. Donnelly is the efficient capital deployment choice in the McCall corridor for investors who want ski and lake vacation rental income without committing McCall-level capital. McCall wins on amenities and absolute income; Donnelly wins on yield per dollar invested.
3) Why does the guide emphasize “dual-season” positioning as a key investment strategy in Donnelly?
Answer: D
The guide’s seasonal analysis shows that a pure ski property at Tamarack earns 60-70% of its revenue in winter and becomes significantly less productive in summer. A property with Lake Cascade access earns meaningful summer income independently of snow conditions. This dual-season structure reduces the impact of a poor snow year, prevents the dramatic fall-off that single-season ski markets experience, and creates a more even annual income distribution. The guide specifically recommends buying for both demand sources rather than one as the primary risk mitigation strategy for Donnelly investors.
4) What does the guide identify as the single highest-ROI investment an owner can make after purchasing a Donnelly STR property?
Answer: A
The guide identifies professional photography as the single highest-ROI investment for a Donnelly STR property after purchase. In a small, seasonal market where most competing properties have mediocre smartphone photos, a $500 professional photoshoot that generates even $3,000/year in additional bookings (from higher visibility and conversion) returns 600% annually on that photography investment. This is a recurring benefit that compounds each year. The guide notes that poor photography is one of the leading causes of underperformance in small-market vacation rentals where inventory quality and trust signals dominate booking decisions.
5) What unique financing advantage does the guide highlight for Donnelly investors who plan personal use?
Answer: C
The guide highlights that investors who genuinely plan personal use of a Donnelly property can access vacation home financing at 10-15% down instead of the 25% required for investment property loans. On a $450,000 purchase, this difference is $45,000 to $67,500 in required down payment. The vacation home rate is also lower than investment property rates. The guide is careful to note this requires genuine personal use intent; using a vacation home loan on a property never personally visited creates mortgage fraud risk. The IRS 14-day/10% rule also affects tax deductibility of losses, making CPA consultation essential for the hybrid personal use/STR strategy.
