A rent roll is a claim until it is checked against the leases behind it. For an Aspen exchanger comparing multi-tenant replacement candidates, that check is where real diligence starts, well before a property earns a spot on the 45-day identification list.
Reading Past the Summary Line
A rent roll summary shows total units or suites, total rent, and an occupancy percentage, and none of those three numbers means much until they are broken apart. The analysis rebuilds the rent roll tenant by tenant: current rent against market rent for that unit or suite type, lease start and expiration date, any concessions or free-rent periods still in effect, and whether the tenant is on a month-to-month status that inflates apparent occupancy without providing durable income.
For an Aspen exchanger moving proceeds from a single high-value asset into a multi-tenant replacement, this line-by-line rebuild is the fastest way to see whether the seller's asking price is supported by real, current income or by a rent roll that has been optimistically dated or selectively presented.
Concentration and Rollover Exposure
Two properties with identical total rent can carry very different risk depending on how that rent is distributed. A retail building with sixty percent of its income tied to one tenant has a different risk profile than one where no single tenant exceeds fifteen percent. The rent roll analysis flags concentration by tenant, by lease-expiration year, and by tenant industry, so a multifamily, retail, or medical office candidate that looks stable on the summary line does not turn out to have half its leases rolling in the same eighteen-month window.
This matters directly for exchange timing: a property with heavy near-term rollover is a bigger underwriting lift inside the 180-day closing period than one with a laddered lease schedule, because the buyer's lender will ask the same rollover questions before funding.
Reconciliation Checklist
Every rent roll pulled for an Aspen exchange candidate is run against the same checklist before the property is trusted enough to identify.
- Current rent versus market rent by unit, suite, or space type
- Lease expiration schedule, grouped by twelve-month rolling windows
- Concessions, free rent, and any below-market renewal options in force
- Tenant concentration by percentage of total rent and by industry
- Month-to-month tenancies flagged separately from term leases
Matching the Rent Roll to the T12 and the Leases
A rent roll that does not tie out to the trailing twelve-month financial statement is a warning sign, not a rounding error. The analysis cross-checks total scheduled rent on the roll against actual collected rent on the T12, and pulls a sample of underlying leases to confirm that the rent roll figures match the executed documents rather than a leasing agent's projection. Where the two do not match, the difference gets a written explanation before the property moves forward, not a shrug.
This reconciliation work should be finished, or at least well underway, before day 45, since a property that fails the cross-check needs to be replaced on the identification list while there is still room to substitute a stronger candidate.
Fit and Related Coordination
Rent roll analysis applies to any multi-tenant replacement candidate: multifamily, retail centers, medical office buildings, and mixed-use properties all carry the same underlying risk of a rent roll that overstates real income. It pairs directly with T12 financial review and feeds the underwriting file that lender preflight coordination and tax advisor and CPA coordination both draw from once a property is close to identification.
For an Aspen exchanger comparing several serious candidates at once, this reconciliation is what separates a genuinely comparable shortlist from a set of properties that only look alike on their marketing summaries. Two buildings advertised at similar rent levels can carry very different rent-roll quality once concessions, month-to-month tenancies, and rollover schedules are laid side by side, and that difference belongs in the file before either property reaches the identification list, not discovered afterward during lender underwriting.
Common 1031 Exchange Questions
Why isn't the total rent figure on a rent roll enough by itself?
Total rent can be inflated by month-to-month tenants, concessions still in effect, or below-market renewal options that will reset lower. The analysis breaks the total apart tenant by tenant so the real, durable income is visible before a property is identified.
What counts as dangerous tenant concentration?
There is no fixed percentage that applies to every property type, but any single tenant or lease-expiration window that represents an outsized share of total rent should be flagged and discussed with the investor's advisors before the property is treated as a strong candidate.
What happens if the rent roll does not match the trailing twelve-month financials?
The discrepancy gets a written explanation and, if it cannot be resolved, the property is generally set aside in favor of a candidate with cleaner documentation. This check is done before identification, since the three-property and 200% rules limit how many candidates can be carried on the list.
Does rent roll analysis apply only to multifamily properties?
No. Retail centers, medical office buildings, industrial flex space, and mixed-use properties all use rent rolls, and the same tenant-by-tenant reconciliation applies regardless of asset class.
How does this connect to the exchange deadline calendar?
A property that fails rent roll reconciliation needs to be replaced on the 45-day identification list while there is still time to find a stronger substitute. Running this analysis early protects the identification strategy rather than discovering problems after the window has closed.
