OBBBA and Real Estate: Every Change That Affects Investors

#The big picture for real estate investors

OBBBA created the strongest real estate tax-strategy climate since TCJA in 2017. Every major lever for real estate investors got better. Bonus depreciation came back to 100% and stayed there. QBI became permanent. Opportunity Zones expanded into rural areas with richer benefits. The SALT cap rose a lot. The estate tax exemption permanently doubled.

This article is the cross-references hub for real estate investors. Each provision has its own deep-dive article; this article is the consolidated map.

#Change 1: 100% bonus depreciation, permanent

Effective: property you bought after January 19, 2025. If you signed a binding contract on or before that date, the old lower rate can apply.

The single biggest provision for real estate investors. The bonus depreciation phase-down that was running its course (60% → 40% → 20% → 0%) is dead. Property with a recovery period of 20 years or less gets fully deducted in the year placed in service. That includes the 5/7/15-year cost-seg-eligible portions of real estate.

Impact on cost segregation: On a $500,000 rental, a study often moves part of the building cost into 5, 7, and 15 year property. Land does not count. How much depends on the property, often around $140K. Under 100% bonus, that entire amount is deducted in year one. If the loss can offset your wages, a $140,000 deduction saves real money. At the 24% to 37% tax brackets, that is about $34,000 to $52,000. You only get it if you qualify as a real estate professional or meet the short-term rental rules. Some of the tax comes back if you sell.

Action items:

• For any property acquired post-Jan-19-2025, run cost seg if you haven’t already
• For older properties never cost-seg’d, consider a Section 481(a) look-back study (catch up missed accelerated depreciation in current year)
• Time future acquisitions to align with high-income years where the deduction value is highest

#Change 2: QBI deduction permanent (where rentals qualify)

Effective: tax years beginning after December 31, 2025.

QBI deduction (20% of qualified business income) applies to rental real estate. But it only applies when the activity rises to the level of a “trade or business” under IRC Section 162. The IRS provides a safe harbor (Rev. Proc. 2019-38) for rental real estate enterprises that meet specific operational requirements:

• 250 or more hours of rental work a year, for a rental under 4 years old. Older rentals need it in 3 of the last 5 years. Triple-net leases and homes you use yourself do not qualify.
• Separate books per enterprise (each property or group).
• Contemporaneous records. Attach the IRS statement to your return each year.

Pre-OBBBA, this QBI eligibility was set to end at the end of 2025. Now it’s permanent.

If your rental counts as a business, you may deduct up to 20% of its net income. Your taxable income can lower that number. At higher income, the wages you pay and the cost of the property can too.

Action items:

• Verify your rentals meet the 250-hour + separate-books + records safe harbor
• Document hours contemporaneously (we recommend a shared Notion log or similar)
• You may group all your similar rentals into one enterprise, so the hours count together. You cannot group homes with commercial buildings. Once you group, new rentals of that type go in the group too.

#Change 3: SALT cap expansion to $40K through 2029

Effective: the cap is $40,000 for 2025 and $40,400 for 2026. It grows 1% a year through 2029. Say your income is over $505,000 in 2026. The cap shrinks by 30 cents for every extra dollar, down to $10,000. In 2030 it goes back to $10,000 for everyone.

For real estate investors with high property tax bills (Texas property owners, especially), the SALT cap matters a lot. The old $10,000 cap was easy to pass with a high-tax primary home plus state income or sales tax. The post-OBBBA $40K cap works better for high-property-tax households.

Note: property tax on rental property is deducted on Schedule E as a rental expense. It is NOT subject to the SALT cap, so rentals do not push anyone over the cap. The SALT cap covers property tax on your home. It also covers either your state income tax or your state sales tax. You pick one of those two, not both.

For ETS clients with $20K+ of property tax on their primary residence, this matters. That is common in Bexar, Travis, Williamson, Harris, Dallas, or Collin counties in Texas. If you itemize, the higher cap can save you real tax in 2025 to 2029. Add up your home mortgage interest, state taxes, and gifts to see if itemizing beats the standard deduction.

#Change 4: Opportunity Zones permanent + Rural OZ category

Effective: the program is permanent now. The lower 50% rebuild test for rural zones started July 4, 2025. The 30% rural step-up and the new 5-year deferral apply to money put into a fund after December 31, 2026. A new round of zones is picked starting July 1, 2026, and those zones start in 2027.

OBBBA permanently extended the Opportunity Zone program. It also created a new Rural OZ category with richer benefits:

• For money put in after 2026, you get a basis step-up after 5 years. It is 10% in a standard fund and 30% in a rural fund. Money put in during 2026 gets no step-up.
• Reduced “substantial improvement” requirement of 50% (vs. 100% for standard OZ real estate)

A fund lets you push a gain out 5 years, not forever. If you invest in a fund in 2026, the gain is still taxed on your 2026 return. A 1031 exchange can defer a gain until you sell. A fund can also make growth tax-free if you hold it 10 years. We compare both before you choose. The Rural OZ category opens new investment lanes in lower-population areas.

#Change 5: Estate exemption permanent at $15M

Effective: January 1, 2026.

For real estate investors with substantial portfolios ($10M+ net worth), estate planning matters. The 2026 exemption is $15 million per person, and it grows with inflation after 2026. A couple can use $30 million only if the first spouse’s unused amount is saved. That takes either filing a Form 706 or good estate planning.

Most real estate investors who built portfolios over 20+ years end up in the $5M to $30M+ net worth range. The higher exemption means most ETS-client real estate portfolios won’t face federal estate tax at all.

Action items:

• Recalibrate estate plans under the new exemption
• Continue annual exclusion gifting for wealth-transfer efficiency
• For $15M+ households, layer ILITs, SLATs, or other irrevocable structures with your estate attorney

#What OBBBA did NOT change

Three things real estate investors sometimes assume OBBBA changed that it did NOT:

#Section 1031 like-kind exchange

Unchanged. Still real estate only. You still have 45 days to name the new property. You get 180 days to close, or your tax return due date if that comes sooner. You almost always need a qualified intermediary to hold the cash. The same taxpayer must sell and buy.

#Real Estate Professional Status (REPS) rules

Unchanged. You still need over 750 hours in real estate work. More than half of all your work time must be in real estate too. You must also take part in the rentals in a real way. Or you can choose to treat them as one activity. Being a real estate professional does not by itself make all rentals non-passive. Keep a time log. It is the best proof if the IRS asks.

#Short-Term Rental (STR) Loophole

Unchanged. Still requires average stay of 7 days or less. Still requires you to take part in a real way. One common test is more than 100 hours and at least as many hours as any other person. Other tests, such as 500 hours, also work. Still allows non-passive treatment of losses.

#Combined planning moves for real estate investors

The OBBBA-driven moves to revisit for ETS real estate clients:

1. Cost seg every property acquired post-Jan-19-2025. The 100% bonus depreciation makes cost seg ROI obvious. If you have W-2 income or other active income to offset (via STR loophole, REPS, or short-term rental classification), the year-one savings are substantial.

2. Section 481(a) look-back on older properties without cost seg. For properties owned 2+ years that never had cost seg, the look-back study lets you catch up the missed depreciation in the current year. The size depends on the year you started renting the property. Property from 2022 or before could have had 100% bonus. Property from 2023 or 2024 had 80% or 60%. The deduction uses the bonus rate for the year the property was placed in service, not necessarily 100%.

3. Verify QBI eligibility on rental portfolios. The 250-hour safe harbor + separate books + records. If you don’t meet the safe harbor, document the time-and-services pattern that supports a trade-or-business position regardless.

4. Evaluate Opportunity Zone strategies for new capital gains. QOZ is now permanent, but the deferral is not like a 1031. A fund lets you push a gain out 5 years, not forever. For money put in after 2026, you get a 10% step-up, or 30% for a rural fund. The growth can be tax-free if you hold 10 years. We compare this against 1031 before you choose.

5. Estate plan recalibration for substantial portfolios. The $15M exemption is a different planning landscape. SLATs, ILITs, dynasty trusts: all still useful but the urgency around “lock in before sunset” is gone.

6. SALT cap planning for high-property-tax households. $40K cap means itemization makes sense for many households who took the standard deduction pre-OBBBA. Re-evaluate itemize vs. standard each year through 2029.

#Common questions

What’s the single biggest change for real estate investors? 100% bonus depreciation permanent. The cost-seg-plus-bonus-depreciation combination is the highest-leverage real estate tax move in the IRC, and it just became permanently available again.

Should I do cost seg on every rental I own? A cost seg study often makes sense for a rental with $300,000 or more of cost. It must be a loss you can use. Some of the tax comes back when you sell (ordinary-rate recapture under section 1245 on the 5/7/15-year pieces). Some states do not allow the extra deduction. Get a quote before you decide.

Does OBBBA affect short-term rentals differently than long-term rentals? The STR Loophole mechanics didn’t change. What did change is the bonus depreciation rate, 100% (post-Jan-19-2025) instead of 40%-20%-0%. For STR investors stacking cost seg + STR loophole, the headline savings are larger.

Does the 30% Rural OZ step-up replace the original 5-year and 7-year step-ups? The original 5-year (10%) and 7-year (additional 5%) basis step-ups had specific TCJA-era deadlines that already expired. The new Rural OZ 30% step-up is a fresh provision specific to Rural QOFs.

Should I 1031 or QOZ? Depends on goals. 1031 keeps you in direct real estate ownership; QOZ moves you into a fund vehicle. 1031 defers indefinitely (until sale); QOZ defers + offers 10-year tax-free appreciation. We model both during Strategic tier engagements.

Does OBBBA affect rental losses claimed against W-2 income? Not directly. The rules for using rental losses against wages did not change. You still need REPS or the STR rules. But a rule that caps how much business loss you can use in one year is now permanent. It is $256,000 for single filers and $512,000 for joint filers in 2026. Any extra carries to the next year, so a big cost-seg loss can still run into this cap.

If you own real estate and haven’t reviewed your post-OBBBA position, the Discovery call is the right next step. Cost seg + STR/REPS + 1031 + OZ all layer together under post-OBBBA rules.
