GuidesBUILDING DILIGENCE

The apartment is fine.
Check the building.

Physical inspection covers the unit. What costs buyers money is the building's balance sheet — an underfunded reserve, a facade cycle arriving, an assessment discussed but not yet voted.

Before you read on

  • General information as of August 2026, not legal, tax or engineering advice.
  • Every building sets its own practice. What follows is the review a buyer's attorney and agent normally conduct before contract.
  • A seller or managing agent unwilling to produce these documents has told you something useful.

Point 1A low monthly charge is not automatically good news

It is either genuine efficiency or a deferred bill, and the financial statements say which.

Buyers filter for low common charges, and the instinct is understandable — it is a monthly cost that never ends and never builds equity. But the charge is a symptom rather than the disease. A building well below its neighbours is either efficient by design — no doorman, no amenities, modern systems — or it is underfunding reserves.

Reserve contributions are the line boards cut when they want the monthly figure to look attractive to buyers. New York’s facade inspection cycle and elevator compliance requirements arrive on a schedule regardless of what has been set aside, and the shortfall reappears as a special assessment on whoever owns the apartment that year.

Point 2The six documents, and what each one answers

DocumentThe question it answers
Audited financial statements, two yearsIs the building solvent, and is the reserve real
Reserve balance in dollarsCould it absorb one major capital project
Assessment historyHas the board been funding work or deferring it
Board minutes, two yearsWhat is being argued about but not yet decided
Current budgetWhat the charges actually fund, line by line
Litigation disclosureIs the building in dispute with a sponsor or a contractor

Minutes are the most revealing and the most often skipped. They record the problems that have not yet become numbers.

Point 3What to look for inside them

Funded versus planned
THE GAP

A capital project approved without a funding source becomes an assessment. Compare what the board intends to do against what it has set aside.

Reserve against one project
SCALE TEST

Ask what a single facade project on a building of that height and age costs, then read the reserve balance against it.

Repeated small assessments
PATTERN

Frequent small assessments in a well-run building can be prudent. A long silence in an ageing building is a warning rather than a comfort.

Sponsor unsold units
CONTROL

While a sponsor holds a significant block it controls the board, sets budgets, and can dispose of units in bulk at a discount.

Arrears and collections
NEIGHBOURS

Owners behind on charges shift the burden to those who pay. High arrears in a small building is a genuine risk to the budget.

Insurance history
CLAIMS

Repeated claims raise premiums permanently and can indicate a recurring physical problem the statements alone do not name.

Point 4Co-op specifics: the lease is the constraint

In a cooperative the proprietary lease decides whether an approved purchase is actually usable.

A co-op’s proprietary lease governs subletting, renovation and, in many buildings, whether the apartment must be a primary residence. Buyers who intend to be away for months, to let the apartment, or to renovate significantly should read the lease before making an offer rather than after board approval.

Co-op financial statements also carry an item condominium buyers never see: the building’s underlying mortgage. Its balance, rate and maturity affect maintenance charges directly, and a refinancing due in a higher-rate environment is a foreseeable increase rather than a surprise.

Point 5Where new construction differs

A new building has no financial history, so the review shifts to the offering plan and the projected first-year budget. Those projections are prepared before anyone knows how the building runs: staffing is estimated, insurance is quoted without a claims history, and reserve contributions are set at a level that helps units sell.

Underwrite above the projection rather than at it, and compare the projected charge per square foot against operating buildings of similar scale and staffing. Establish when sponsor control of the board transfers, and how many units remain unsold — until that block clears, someone still selling apartments is setting your monthly costs.

What is the single most useful document?

Board minutes for the last two years. They record deferred projects, disputes and assessments under discussion — the problems that have not yet reached the financial statements.

How large should a reserve fund be?

There is no universal figure. The practical test is whether it could absorb one major capital project for a building of that size and age without an assessment.

Is a special assessment a red flag?

Not by itself. An assessment funding necessary work in a building that discusses it openly is governance working. A pattern of emergency assessments with no planning is the warning.

Can I get these documents before making an offer?

Usually yes for a resale, through the managing agent or the seller's attorney. In new development the offering plan is public and the projected budget is inside it.

What if the seller will not provide them?

Treat that as a finding. In a market where these documents are routinely produced, reluctance is information about either the building or the seller.

Does the inspection cover any of this?

No. A physical inspection covers the unit's systems and visible condition. Building finances, litigation and governance are a separate review conducted on paper.
