Buying a Big Bear Cabin in 2026? New Tax Benefits Every Second-Home Buyer and Investor Should Know

By Holly Gardner | Big Bear Real Estate Specialist | Keller Williams Mountain Resort Group

1. The SALT Deduction Has Increased, and Second-Home Buyers Should Pay Attention

One of the most relevant changes for California homeowners is the expansion of the federal state and local tax deduction, commonly known as SALT.

Under the One Big Beautiful Bill Act, the federal SALT deduction limit increased significantly from the previous $10,000 cap.

For the 2026 tax year, the general SALT deduction limit is $40,400 for eligible taxpayers who itemize their deductions. For married taxpayers filing separately, the limit is generally $20,200.

There is an important income limitation. For 2026, the higher deduction begins phasing down when modified adjusted gross income exceeds $505,000 ($252,500 for married filing separately), but generally does not fall below $10,000 ($5,000 for married filing separately).

Why does this matter to Big Bear buyers?

Imagine you own a primary residence in Orange County or Los Angeles and are considering purchasing a second home in Big Bear.

You may already pay substantial California income taxes and property taxes on your primary residence. Adding a second home creates another property tax obligation.

With the higher SALT deduction limit, some qualifying taxpayers who itemize may now be able to deduct more of their combined eligible state income taxes and property taxes than they could under the previous $10,000 cap.

For example, suppose your annual eligible taxes include:

• $19,000 in California state income taxes
• $9,000 in property taxes on your primary residence
• $7,000 in property taxes on your Big Bear second home

That's $35,000 in potentially deductible state and local taxes.

Under the former $10,000 cap, much of that amount would have been excluded from the federal deduction. Under the 2026 rules, the full $35,000 may fall within the expanded limit, assuming you qualify and itemize.

Does SALT apply to primary residences? Yes. Eligible personal property taxes on both primary residences and second homes may be included, subject to the applicable limits. Property taxes properly deducted as rental business expenses are generally treated separately from the personal SALT limitation.

2. 100% Bonus Depreciation Is Back for Qualifying Investment Properties

Another major opportunity for certain real estate investors is the restoration of 100% bonus depreciation.

Under federal legislation enacted in 2025, qualifying assets acquired after January 19, 2025, may be eligible for 100% first-year bonus depreciation.

Instead of depreciating certain business assets over several years, qualifying investors may deduct their eligible cost in the year those assets are placed in service.

For a furnished Big Bear vacation rental, potentially eligible assets could include furniture, mattresses, appliances, televisions, certain flooring, and qualifying outdoor improvements.

The cabin building itself generally does not qualify for 100% bonus depreciation.

What about a turnkey furnished Big Bear cabin?

Suppose you purchase a property that includes furnishings and appliances.

Your CPA may be able to identify and properly allocate part of the purchase price to eligible personal property, rather than treating the entire purchase as one building.

This can create opportunities for accelerated depreciation, assuming the property and assets meet the applicable requirements.

Does this apply to your personal vacation cabin? Generally, no. Bonus depreciation is for qualifying business or income-producing assets, not furniture and appliances purchased for a home used exclusively for personal enjoyment.

3. Cost Segregation: A Strategy Worth Exploring

Cost segregation may sound complicated, but the concept is straightforward.

A cost segregation study identifies eligible components of an investment property that can be depreciated more quickly than the building.

Residential rental buildings are generally depreciated over 27.5 years, while certain furnishings, equipment, and land improvements may qualify for shorter depreciation periods.

Example: A $700,000 Big Bear investment cabin

Imagine purchasing a furnished Big Bear vacation rental for $700,000.

After allocating the purchase price between land, the building, and other assets, a qualified study identifies $100,000 of eligible assets that may qualify for accelerated depreciation.

Under the federal 2026 rules, some or all of those assets could potentially qualify for 100% bonus depreciation.

That could mean a substantial first-year deduction.

But remember: a $100,000 tax deduction is not the same as $100,000 in tax savings. Whether that deduction can reduce your other taxable income depends on passive activity rules, material participation, your overall tax situation, and other limitations.

A cost segregation study also has a cost, and accelerated depreciation may create depreciation recapture consequences when you sell the property.

For the right investment, though, it's a strategy worth discussing with your CPA.

4. Can a Big Bear Short-Term Rental Offset Your W-2 Income?

This is one of the most interesting tax questions for vacation rental investors.

Ordinarily, losses from rental real estate are considered passive. That generally limits their ability to offset wages, salaries, and other nonpassive income.

However, some short-term rental activities receive different treatment.

If the average guest stay is seven days or less, the activity generally isn't classified as a rental activity for federal passive-loss purposes.

If you also materially participate in operating the property, qualifying losses may potentially offset nonpassive income, subject to other limitations.

What does material participation mean?

It means being sufficiently involved in the actual operation of the business under IRS participation tests.

Activities might include coordinating reservations, communicating with guests, managing cleaning and maintenance, and handling day-to-day operations.

However, simply owning an Airbnb or occasionally checking on a property doesn't automatically qualify. Hiring a full-service property manager may also affect your ability to satisfy the participation requirements.

Careful recordkeeping is essential.

The opportunity: For certain qualifying investors, the combination of short-term rental treatment, material participation, and accelerated depreciation may create significant federal tax benefits.

This is a specialized strategy that should be evaluated with a CPA before purchasing.

5. Furnished Vacation Rentals May Offer Additional Write-Offs

A Big Bear rental cabin comes with operating expenses, and many ordinary and necessary expenses associated with a legitimate rental business may be deductible.

Examples include:

• Mortgage interest attributable to the rental
• Property taxes attributable to rental activity
• Property insurance and management fees
• Cleaning, repairs, and routine maintenance
• Utilities, internet, and guest supplies
• Advertising and booking platform fees
• Eligible furniture, appliances, and equipment through applicable expensing or depreciation rules

Major renovations and improvements are generally treated differently from routine repairs and may need to be capitalized and depreciated.

For a property used partly as a rental and partly for personal vacations, expenses must generally be allocated appropriately. Personal-use rules may also limit deductions.

A furnished cabin can be attractive to guests and may offer investment-related tax benefits, but the furnishings and amenities should make financial sense independently of any deduction.

6. What If You Just Want a Second Home for Family Vacations?

Not every Big Bear buyer wants to run a vacation rental business.

For many families, the dream is simply to have a mountain getaway for skiing, hiking, boating, and making memories.

A qualifying personal-use second home may still provide certain federal tax benefits.

Mortgage interest

Mortgage interest on a qualifying second home may be deductible if you itemize, subject to the applicable combined mortgage debt limits and other requirements.

Property taxes

Eligible property taxes on a personal-use second home may count toward your federal SALT deduction, subject to the 2026 limit and income restrictions discussed earlier.

Occasional rental income

Here's a provision many second-home owners find interesting.

If your vacation home qualifies as a residence under IRS rules and you rent it for fewer than 15 days during the year, the rental income generally isn't included in federal taxable income.

That could make renting your cabin during a busy holiday period worth exploring.

However, you generally cannot deduct rental expenses attributable to those rental days under this special rule, and local rental permit and tax requirements may still apply.

The key distinction: A personal-use second home may qualify for certain itemized deductions, but it generally doesn't qualify for the same business depreciation deductions available to investment properties.

7. Does Buying Before December 31, 2026, Matter?

Potentially, yes.

For investors seeking depreciation deductions on their 2026 federal tax returns, timing can matter.

Simply signing a purchase agreement or closing escrow by December 31 may not be enough.

To claim depreciation for 2026, the property or qualifying assets generally must be placed in service during 2026.

For a vacation rental, that typically means the property is ready and genuinely available for rental use, not merely purchased with the intention of renting it someday.

Depending on the property, that may involve completing furnishings, satisfying applicable local permit requirements, and making the cabin available for guests.

An important clarification: the restored 100% bonus depreciation provision is not currently scheduled to expire on December 31, 2026.

The year-end opportunity is the possibility of claiming qualifying deductions for the 2026 tax year rather than a later year.

Buyers should never rush into a property purchase solely to obtain a deduction.

8. Big Bear Rental Regulations and California Tax Rules Matter

Big Bear is not a single regulatory jurisdiction.

A property within the City of Big Bear Lake may be subject to different short-term rental rules than a property in an unincorporated San Bernardino County community.

That distinction can affect permitting, operating requirements, occupancy restrictions, and rental taxes.

Before purchasing an investment property, verify that your intended rental use is permitted and financially practical.

California tax treatment also deserves special attention. California generally does not conform to federal bonus depreciation rules, so a large federal depreciation deduction may not produce a comparable California income-tax deduction.

And remember, under California's Proposition 13 system, purchasing a property generally establishes a new assessed value based on the change in ownership. Supplemental property tax bills may follow.

It's important to evaluate the property's complete financial picture, including financing, insurance, maintenance, utilities, management, taxes, and realistic rental demand.

Is 2026 a Good Time to Buy a Big Bear Cabin?

For the right buyer, 2026 may offer an interesting combination of lifestyle benefits, potential rental income, and tax-planning opportunities.

The expanded SALT deduction may be especially relevant to California homeowners considering a personal-use second home. For investors, 100% bonus depreciation, cost segregation, and short-term rental tax treatment may create additional possibilities.

But the best purchase is one that works for your financial goals even without a tax deduction.

That's where local real estate knowledge matters.

Whether you're interested in a cozy Moonridge getaway, a furnished Big Bear Lake cabin, a property in Big Bear City, or a retreat in Sugarloaf or Fawnskin, I can help you explore available properties, understand the local market, and identify important questions to ask before buying.
