Cost seg on a property bought with a tenant already in place — does the lease change

Say you buy a rental with a tenant already in place — lease has months left to run, rent is below market. The property is rented from day one, so placed-in-service timing is straightforward. But does the in-place lease change the cost seg study itself?

My read is that the study is about the physical components, so the lease shouldn't change what's 5, 7, or 15-year property. Where I'm less sure: does the lease affect the land/building allocation, or how the purchase price gets allocated between land, building, and the lease itself?

Has anyone run a cost seg on a tenant-occupied purchase? Did your CPA or the study firm treat anything differently because of the lease?

    Your read is right, and the tax code answers the allocation question directly. Under Section 167(c)(2), when you buy property subject to a lease, no part of the purchase price is allocated to the leasehold interest. The entire basis stays with the property and is split between land, the building and the shorter-life components the study identifies. So unlike financial-statement purchase accounting, you don't carve out an in-place lease intangible for tax, and a below-market rent doesn't reduce your depreciable basis.

    A few things the lease can still affect:

    1. Tenant-owned improvements. If the tenant installed and owns fixtures under the lease, they aren't yours to depreciate. The study should only cover what you acquired.

    2. Access. The engineer needs to inspect an occupied unit, so build in the tenant notice your lease and state law require.

    3. Placed-in-service date. Since it's rented on day one, the acquisition date is the placed-in-service date, and property acquired after January 19, 2025 qualifies for 100% bonus depreciation on the 5, 7 and 15-year components.

    The land/building split is still driven by the assessor ratio, an appraisal or the engineer's estimate, not by the lease.

    Your read on the components is right. The lease doesn't change what's 5 or 15 year. On the allocation, 167(c)(2) covers it: if you buy property subject to a lease, none of the basis goes to the leasehold and the whole basis gets depreciated with the property. So for tax there's no separate in-place lease asset, even if a book purchase price allocation would show one. Land split works the same as any other purchase. The tenant really only matters for the site visit, since you're scheduling around someone living there, so inspection report photos and appliance details help fill gaps. 167(c)(2) is the thing to point your CPA to if an intangible comes up.

    Jason covered the lease question, so I'll add the part that usually matters more here, the paperwork behind the allocation. The lease generally doesn't change the study, but the purchase price still has to be split between land and building from something defensible, like the county assessor ratio or the appraisal, and that split should be in your file before the engineer starts.

    To put numbers on it, say you pay $400,000 and the assessor ratio is 20% land. That's $80,000 land and $320,000 of depreciable basis. If the study moves 25% of the building, $80,000, into 5, 7 and 15 year property, that can be expensed up front with bonus, and the remaining $240,000 is about $8,700 a year over 27.5 years.

    Also keep the closing statement and the study together, and put the date the unit was ready and available for rent in your records. If a tenant installed fixtures, ask the engineer to leave those out. Your CPA will want all of that on one page at filing time.

    Agree with Jason and Roel on 167(c)(2). That’s the right cite, and it settles the intangible question for tax purposes. I’d add a couple of things we see come up on tenant-occupied purchases.

    First, the closing statement. Prorated rent and the security deposits transferred to you show up as credits on the settlement statement, and people sometimes treat them as a reduction to purchase price. They aren’t. They’re adjustments for rent and liabilities you took over, not a change to what you paid for the property. Have your CPA work from the actual contract price plus capitalizable closing costs, so the study starts from the right basis.

    Second, and this is the one that catches people, think about whether you can actually use the deduction before you order the study. With 100% bonus back for property acquired after January 19, 2025, a cost seg on a long-term rental can generate a large loss in year one. For most investors that loss is passive. Unless you qualify as a real estate professional, or have other passive income to absorb it, it gets suspended and carried forward. You still get it eventually, but the year-one benefit you were sold on may not show up on this year’s return. It’s also worth checking your state, since some states don’t follow federal bonus depreciation.

    None of that changes your read on the study itself, which is correct. The lease doesn’t change the components. Just run the numbers on how the loss will actually hit your return first.

    I don’t really see how having a resident in place changes things from a tax perspective. At purchase, you separate out building and land. If you do any improvements before the cost seg, those should also be included. So no, this does not affect the split between land and building
