Rent Roll Analysis
A rent roll is a lot like a building's work order log: read it closely and it tells you what's actually happening, skim it and you get whatever story the seller wants told. For a replacement property search running against the 45-day identification clock, there isn't time to find out the hard way which version you got.
Reading a Rent Roll Like You Read a Work Order Log
Current rent, lease expiration, and unit count are the easy fields. The useful read comes from cross-checking those numbers against collections, looking for units billed at one rate but paid at another, and noticing how many leases roll over in the same six-month window. A rent roll with half the building expiring at once is a tenant retention problem waiting to surface, no matter how strong the current income looks. That concentration risk rarely shows up on a summary page, so it takes actually scanning the expiration column line by line to catch it.
Seasonal Tenants and the Snowbird Occupancy Trap
Miami multifamily and short-term-adjacent properties can carry seasonal residents who show up as full occupancy on paper for part of the year and empty units the rest of it. A rent roll pulled during peak season tells a different story than one pulled in the off months, so it matters when the snapshot was taken, as much as what it shows.
Corporate leases and month-to-month arrangements common in Brickell and downtown towers add another layer, since those tenants can turn over faster than a standard annual lease would suggest. Ask for occupancy pulled at two different points in the year before relying on a single snapshot to represent the whole building.
Concessions That Hide a Downtime Problem
A free month or reduced rent for the first quarter of a lease often shows up buried in a footnote rather than the headline rent figure, and it can mean the unit sat vacant longer than the seller wants to advertise. Sometimes a concession is covering for a maintenance issue that kept the unit offline, elevator downtime that limited showings, or a slow turn between tenants.

- lease expiration concentration by month
- concession history and the reason behind each one
- tenant concentration by unit type or floor
- maintenance or downtime notes tied to specific units
- rent versus current market comparable
Tying the Rent Roll to the T12 Before You Believe Either One
A rent roll and a trailing twelve-month financial statement should tell the same story, and when they don't, that mismatch is worth chasing down before it becomes your problem. Billed rent that doesn't match reported income usually points to collection issues, unrecorded concessions, or units that were vacant longer than the rent roll implies.
This cross-check matters more in a market like Miami where turnover, seasonal patterns, and a wide range of ownership sophistication mean the quality of seller-provided documents varies a lot from one listing to the next. A seller who hesitates to hand over both documents together, or asks why you need both, is telling you something worth paying attention to before the property advances any further.
What a Clean Rent Roll Buys You on the 45-Day Clock
A property with a rent roll that survives this level of scrutiny moves through lender underwriting faster, which matters when the identification window is already running. That speed advantage is worth factoring into how a property gets ranked on an identification list alongside assets that look better on the surface but haven't been checked this closely.
Coordinate findings with the qualified intermediary and the investor's tax advisor before finalizing the list, since income quality can affect financing terms that in turn affect the exchange's basis and debt replacement plan. That coordination is a planning step, not tax guidance in itself.
Common 1031 Exchange Questions
Why does the timing of a rent roll snapshot matter for a Miami multifamily property?
Seasonal residents and corporate tenants can make occupancy look stronger during peak months than it holds up the rest of the year. A rent roll pulled during the busiest season can overstate how stable the income actually is.
How can I tell if a concession is hiding a maintenance problem on a rent roll?
Look for concessions clustered around specific units rather than spread evenly across the building, and ask directly what caused each one. A pattern tied to particular floors or unit lines often points to a repeated maintenance or downtime issue rather than routine leasing strategy.
What's the difference between billed rent and collected rent on a rent roll?
Billed rent is what the lease says a tenant owes, while collected rent is what actually came in. A gap between the two signals collection problems that a rent roll alone won't explain, which is why comparing it against the trailing financials matters.
Should a rent roll review happen before or after a property is added to the identification list?
Before, whenever possible. Confirming income quality ahead of time avoids adding a property to the 45-day identification list only to find financing or valuation problems that force a late substitution.
Does rent roll quality affect how a lender underwrites a replacement property?
Yes, lenders look closely at collections consistency and lease expiration concentration, and inconsistent numbers can slow down or change loan terms. That's part of why a clean rent roll review before closing helps keep the exchange timeline on track.
