A rent roll fits on one page and most buyers spend less than five minutes on it. That is the wrong ratio, because every other number in the deal is built on it.
This piece walks the document itself, column by column, and explains what each one tells you and the patterns that should make you slow down. Checking the roll against bank deposits, signed leases, and estoppels is a separate exercise, covered in our guide to reading a rent roll during property review. Here the question is narrower: what does the page in front of you actually say?
An Illustrative Roll
The rows below are invented for a hypothetical eight-unit building in Orange County, but the layout is what a seller’s property manager will typically hand you. Keep it in view while reading the sections that follow.
| Unit | Type | Sq Ft | Lease Start | Lease End | Contract Rent | Market Rent | Deposit | Status |
|---|---|---|---|---|---|---|---|---|
| 1 | 2BR/1BA | 850 | Mar 2014 | MTM | $1,450 | $2,650 | $800 | Occupied |
| 2 | 2BR/1BA | 850 | Jul 2025 | Jun 2026 | $2,595 | $2,650 | $2,595 | Occupied |
| 3 | 1BR/1BA | 620 | May 2026 | Apr 2027 | $2,100 | $2,100 | $0 | Occupied |
| 4 | 1BR/1BA | 620 | — | — | $2,100 | $2,100 | — | Vacant |
| 5 | Studio | 410 | Jan 2021 | MTM | $1,200 | $1,700 | $1,200 | Occupied (mgr) |
Unit and Type
Count the rows and compare the total to the unit count in the marketing package and, more importantly, to the county’s records for the parcel. A nine-row roll on a building permitted for eight units means one of them is a converted garage or a split unit, and you need to know which before you price it.
The unit-type mix tells you who lives there and how the income behaves. A roll heavy in studios turns over faster and costs more per dollar of rent to re-let; a roll of two-bedrooms tends to hold tenants longer. The mix should match the turnover and leasing costs you plan to underwrite.
Square Footage
Divide contract rent by square feet for every row. On a well-run building the figure clusters tightly within each unit type; a row that sits far outside the cluster has a story, and the story is usually a long-tenured tenant, an unpermitted unit, or a typo that has been carried forward for years.
Lease Start and Lease End
Read these two columns together as tenure. Unit 1 in the illustration has been occupied since 2014 with no fixed term, and that combination explains almost everything else on its row: a low rent, a low deposit set under an old policy, and a tenant with the strongest possible protections under California’s statewide rent cap (AB 1482) and any local ordinance layered on top.
A start date with no end date, or an end date years in the past, means the original lease expired and nobody renewed it. That is common on small buildings and not a defect in itself. It does mean the terms in force are whatever the old lease said plus whatever was agreed verbally since, which is a question for the lease file rather than the roll.
Several start dates inside the last ninety days, on a building that has not been renovated, deserve a direct question. New tenancies at full asking rent immediately before a sale can be genuine, or they can be placements made to dress the roll.
Contract Rent
Contract rent is the figure the lease obliges the tenant to pay each month. It is not what was collected, but it is the base for everything else on the page.
Sum the column and annualise it. That is the gross potential rent of the building as currently let, and it is the number every valuation in the offering memorandum starts from. Then look at the spread inside each unit type: two identical 2BR units at $1,450 and $2,595 are one building with two very different tenants, and the gap between them is not a “value-add opportunity” unless the tenant in the cheaper one leaves voluntarily.
Rents ending in odd amounts ($1,437, $2,183) usually reflect years of percentage increases under a rent cap and tell you the owner has been applying the allowable adjustment each year. Rents that are all neat round numbers on a long-held building can mean the opposite: an owner who never raised them, and a roll that is further below market than the “market rent” column admits.
Market Rent
This is the column the seller’s broker filled in, and it is an opinion. Treat it as the broker’s asking price for the upside rather than as data.
Two tests are quick. First, does the market figure vary by unit type and square footage, or is it a flat number pasted down the column? Second, does the most recently leased unit on the roll actually achieve it? In the illustration, unit 3 was let in May 2026 at $2,100, which is the market figure claimed for the 1BR units. That is modest evidence the column is honest for that type. Where the newest lease sits below the claimed market rent, the column is aspirational and you should underwrite to the lease.
Security Deposit
Deposits are money you take on at closing and owe back to tenants later, so the column is a liability schedule as much as a tenant record. Read it for three things.
A deposit equal to one month’s current rent, as in unit 2, is the current norm under California’s 2024 limit on residential deposits. A deposit far below current rent, as in unit 1, is normal for a long tenancy and simply means you have less cover for that unit at move-out. A deposit of zero on an occupied unit, as in unit 3, is the one to ask about: either it was never collected, it was applied to rent at some point, or it is sitting in an account nobody has mentioned.
Status and Notes
Status is where the vacancy actually lives, and where the roll is most often quietly optimistic. “Occupied” should mean a tenant with a lease who is paying. “Notice given,” “eviction pending,” and “occupied, non-paying” are all things that get written as “occupied” on a roll prepared for sale, so ask for the definition in writing.
Unit 5 in the illustration is marked as a manager’s unit. Whether it pays rent, reduced rent, or nothing at all, the income the roll shows for it is not income you will receive unless you keep the same arrangement. The same applies to any unit occupied by a relative of the seller or by a maintenance worker on a trade arrangement. Pull those rows out of your gross-rent total before you do anything else with the number.
The notes column, when there is one, is worth reading last and slowly. “Pays on the 10th,” “has a dog,” and “parking in space 4” are each small; together they are the list of promises you inherit.
What to Write Down Before You Move On
By the end of the walk you should have four figures of your own: the unit count you can verify against the permit record, the annualised contract rent excluding non-paying and related-party units, the number of tenancies old enough that their rent is effectively fixed, and the deposit total you will assume at closing. The rest of the review is built on those four.
