Reading the Financials: How to Evaluate a Co-op or Condo Building's Health
You're not just buying an apartment; you're buying a share of a building's balance sheet. Two identical units can carry wildly different futures depending on whether the building has $4 million in reserves and a new roof, or $80,000 in reserves and a façade order from the city. Your attorney will review the financials — but you should understand them too.
The documents you'll get
Audited financial statements, typically 2–3 years
Board meeting minutes, typically 1–2 years
The budget for the current year
For condos: the offering plan and by-laws; for co-ops: the proprietary lease and house rules
What to look at, in order
1. Reserve fund
The building's savings account for capital work. Rules of thumb vary, but a common benchmark is reserves equal to at least 10% of the annual operating budget — and meaningfully more for older buildings with big-ticket work ahead. Compare reserves against the age and condition of major systems: roof, elevators, boiler, façade, windows, plumbing risers.
A well-funded building with an aging roof is fine. A thin-reserve building with an aging roof means you will pay for that roof, via assessment or a maintenance spike.
2. Underlying mortgage (co-ops only)
Co-op corporations often carry a building-wide mortgage. Check:
Balance relative to the building's value
Maturity date — a mortgage maturing soon must be refinanced at whatever rates prevail, which can push maintenance up sharply
Interest-only vs. amortizing — interest-only keeps maintenance artificially low today and creates a balloon later
A co-op with a big interest-only mortgage maturing in 18 months deserves a hard look.
3. Operating result
Is the building running a surplus or a deficit? A small surplus is healthy. Persistent deficits mean either an assessment or a maintenance increase is coming. Look at the trend across all years provided, not one snapshot.
4. Arrears and delinquencies
The notes usually disclose how many shareholders or unit owners are behind on payments. High arrears in a small building is a warning: those costs get spread onto everyone else, and lenders may balk at financing in buildings with high delinquency (which shrinks your future resale pool).
5. Assessments — current and coming
Check whether a special assessment is active (it's a real cost you'll inherit) and read the minutes for discussion of upcoming projects. Minutes are where boards say the quiet part: "the engineer's report on the façade," "elevator modernization estimates," "the litigation with the contractor."
6. Insurance and litigation
Confirm adequate coverage and check for pending lawsuits. Buildings in litigation can be difficult or impossible to finance, which affects both your purchase and your exit.
7. Compliance and capital exposure
For larger buildings, ask about Local Law 97 (carbon emissions limits with escalating compliance obligations for many buildings over 25,000 sq ft) and Local Law 11 / FISP façade inspection cycles. Both can drive substantial capital spending. A building with a funded compliance plan is in far better shape than one that hasn't started.
8. Concentration risk
In small buildings, one owner holding many units, or heavy sponsor ownership of unsold units, concentrates risk. In condos, high investor/rental ratios can complicate financing for future buyers.
Quick health scorecard
Signal | Healthy | Concerning |
Reserves vs. budget | 10%+ and growing | Under 5%, declining |
Operating result | Small consistent surplus | Repeated deficits |
Underlying mortgage (co-op) | Amortizing, distant maturity | Interest-only, near-term maturity |
Arrears | Minimal | Multiple units, rising |
Minutes tone | Routine maintenance planning | Routine maintenance planning |
Capital plan | Funded, scheduled | "We'll deal with it later" |
The bottom line
Ask your agent for financials early — ideally before you bid, certainly before contract. A cheap apartment in a broken building isn't cheap; it's deferred. Conversely, a slightly pricier unit in a well-run building with strong reserves often carries lower total cost of ownership and resells more easily.
