What Questions Should I Ask My CPA Before Closing on a Rental Property?

I’ve spent the last nine years in the trenches—working with property management teams, haggling with cost segregation firms, and sitting in on those high-stress meetings with CPAs just days 2025 bonus depreciation rules before a closing. If there is one thing I’ve learned, it’s that most investors walk into closing with a "hope-based" tax strategy. They hope they’ll get "huge savings" without ever running the numbers.

Before we dive into the strategy, stop right there. What did you allocate to land? I ask this every single time, and it’s usually the number one reason an investor’s tax projections fall apart. Land is non-depreciable. If your contract doesn't clearly delineate the land value from the improvements, the IRS will happily decide for you—usually in their favor, not yours. Before you sign those closing papers, let’s get your pre closing tax checklist rental strategy in order.

1. The "Bonus" Reality Check: What Actually Qualifies?

One of the biggest pet peeves I have in this industry is hearing people claim the "building is bonus depreciable." That is patently false. You cannot take 100% bonus depreciation on the structural components of a residential rental property. You depreciate the building over 27.5 years.

However, through a cost segregation study, you can identify "personal property" and "land improvements" that *do* qualify for bonus depreciation. This is where the magic happens, but it requires math, not marketing fluff. Use the online bonus depreciation calculator provided by 100 Bonus Depreciation to get a quick look at your potential Year 1 write-offs. If the numbers look thin after a back-of-napkin calculation, a full-blown engineering study might just be an expensive paperweight.

What Qualifies for Bonus Depreciation?

• Land Improvements: Fencing, parking lots, sidewalks, and landscaping (often 15-year recovery).
• Personal Property: Appliances, carpet, window treatments, and specialized millwork (often 5-year recovery).
• Structural Components: (The "No" pile) Roofs, HVAC (usually), foundation, and exterior walls (27.5-year).

2. Passive Activity Loss Limitations: The Dream Killer

Many investors get excited about a massive paper loss in Year 1 from a cost segregation study, only to find out they can’t actually use that loss against their W-2 income. This is why REPS passive loss planning is so critical. If you aren’t a "Real Estate Professional" under IRS rules, your rental losses are generally "passive" and can only be used to offset passive income.

Don't fall for the "huge savings" pitch without asking your CPA: "How do we handle passive activity loss limitations if I’m not a REPS?" You need a plan to either generate passive income to absorb those losses or ensure you meet the criteria for Real Estate Professional Status to treat those losses as non-passive.

3. Acquisition Timing and Ownership Rules

Tax code is sensitive to timing. If you’re closing near the start of the year—specifically looking at the January 19, 2025, milestones or similar look-back periods—you need to understand how your ownership duration affects your ability to claim specific deductions. The 5-year lookback is a common consideration for specific energy-efficient upgrades or previous capital improvements made by the seller. Ask your CPA if the property's history impacts your current depreciation schedule.

4. The Pre-Closing Tax Checklist

I keep a running list of "things to ask your CPA before closing" on a sticky note at my desk. You should keep this in your deal file:

Question Category The Specific Question to Ask Land Allocation How does the purchase price allocation between land and improvements align with the County Assessor’s property valuation? REPS Status What specific records do I need to maintain to prove Real Estate Professional Status if I plan to use losses against active income? Cost Segregation Based on the property's estimated size and age, what is the ROI threshold for justifying a formal cost segregation study? Bonus Depreciation How do current bonus depreciation phase-outs (or active 100% provisions) apply to the specific asset classes within this property? Passive Loss If we trigger a large loss this year, what is the exact mechanism for carrying those losses forward if I have no passive income?

5. Why You Need Professional Guidance (and Where to Find It)

When you are looking to optimize your rental portfolio, lean on resources like Rent Bottom Line to help you understand the intersection of operational efficiency and tax strategy. You shouldn't be guessing about depreciation schedules while you're trying to finalize your financing.

Also, don't forget to leverage technology. Tools are meant to assist, not replace, your CPA. Use the 100 Bonus Depreciation calculator to run those napkin numbers I mentioned earlier. It helps you keep your expectations grounded. If you find a strategy that works, use AddToAny to share these resources with your partners or your legal team so everyone is on the same page before the closing date.

Final Thoughts: Math Over Marketing

The real estate industry is full of people promising "huge tax savings." My advice? If someone can't show you the math, walk away. A rental property is a long-term asset. You don't make decisions based on the current year's tax bill alone; you make them based on how those assets perform over a 10, 15, or bonus depreciation calculator 20-year horizon.

Before you head to that closing table:

• Check your County Assessor's property valuation to ensure your land/building split isn't aggressive.
• Calculate your likely depreciation benefit using a reputable calculator.
• Confirm your status (REPS vs. Passive) with your CPA.
• Ensure your tax plan addresses the reality of your total income, not just your real estate gains.

If you take these steps, you won’t just be closing on a property—you’ll be closing on a business move that makes sense for your bottom line. And for heaven’s sake, keep that land allocation figure reasonable. The IRS auditor doesn't have a sense of humor about "optimistic" land appraisals.
