How do I read a rent roll like a buyer — and what is it hiding?
A rent roll is the building's biography, and buyers read it that way. Look for loss-to-lease (in-place rent versus market, unit by unit), the tenure map (move-in dates tell you which units may turn and which never will), deposit irregularities (missing or oddly sized deposits flag undocumented arrangements), and the Section 8 mix (subsidized tenancies change both income durability and process). Buyers reprice deals at the rent roll because that is the first place the marketing claims meet actual signatures.
The columns that matter.
Move-in date is the most information-dense column on the page. A 1998 move-in at $840 in a $1,900 submarket is the value-add thesis, priced accordingly — the RSO locks the rent, and the tenure tells you not to underwrite a quick turn. What should stop you is the incoherent row: a 2023 move-in at 2005 rent (why?), a unit with no deposit listed (side deal? relative? never documented?), or a rent conspicuously above every neighbor signed a month before listing (staged comp?). Map loss-to-lease per unit, not as a building average — the average hides the fact that the upside is often concentrated in three units held by tenants who will realistically never leave. Then flag every subsidized tenancy and ask for the HAP contracts, because that income is the most verifiable in the building and the paperwork either exists or it does not.
Cross-checks that catch fiction.
The rent roll must reconcile with three other documents, and the gaps are the findings. Bank statements: two or three months of actual deposits should match scheduled collections — a persistent shortfall means non-paying tenants the OM did not mention. Estoppels: each tenant's signed statement of rent, deposit, and terms should match the roll line for line; where it does not, believe the tenant. Utility bills: a unit claimed vacant that is burning gas and electricity is occupied by someone — a holdover, a relative, an unpermitted arrangement — and "vacant" units are also how unpermitted units hide on a roll. This is why buyers reprice at the rent roll stage: the price was negotiated on the seller's story, and due diligence audits it. Sellers who audit their own roll before listing keep their price; sellers who do not, negotiate twice.
What is loss-to-lease?
The gap between in-place rents and current market rents for the same units. In long-held LA RSO buildings it commonly runs 20–40%. It is simultaneously the upside a buyer pays for and the income a seller cannot claim to have — pricing lives in that tension.
What deposit irregularities should worry me?
Units with no deposit recorded, deposits wildly out of scale with the rent, or a ledger that does not sum to the liability the contract transfers to you. Each one usually marks an undocumented arrangement — and you inherit deposits, and the disputes, at closing.
How do I verify a claimed vacancy is really vacant?
Walk it, check utility usage on the house bills, and note the absence of an estoppel. A vacancy is valuable (vacancy decontrol) only if it is real, legal, and permitted — a "vacant" unit that turns out to be an unpermitted tenancy is a liability, not upside.
