A NYC co-op board package is the building's purchase application. It brings together your finances, references and transaction documents so the board can decide whether to approve the sale.

Start with the building's current written requirements. A complete package should be easy to review, with figures that agree across the application and supporting documents. This checklist will help you prepare, but the building's own instructions determine what you submit.

Get the requirements before you need them

Ask for the application, financial guidelines, fee schedule and submission instructions while you are evaluating the apartment. For co-ops covered by NYC's application timing law, the corporation must provide its application and transfer requirements promptly upon request. [1]

Before making an offer, confirm the permitted financing and how the building evaluates income and assets remaining after closing. Raise any purchase arrangement involving a gift, guarantor, trust or another buyer early. Knowing which arrangements the building accepts can save you from pursuing an apartment that does not fit your finances or plans.

Our guide to buying a co-op in NYC explains the broader purchase process.

The board package document checklist

Use the table below to track preparation. These are common categories, rather than requirements imposed on every buyer. The application will specify the periods covered, number of references, forms and signatures it needs.

Document category	What to confirm	Ready
Building application	Every required field, signature and authorization is complete.	[ ]
Financial statement	Account balances, liabilities and monthly obligations match supporting records.	[ ]
Bank and investment statements	The requested periods and all required pages are included.	[ ]
Tax returns and income records	The requested returns, schedules and current income evidence are supplied.	[ ]
Employment or business documentation	The evidence fits how you earn your income.	[ ]
Reference letters	The required types and number of letters are included and signed.	[ ]
Contract and financing documents	The signed contract and applicable lender documents meet the checklist.	[ ]
Other transaction requirements	Requested seller materials, fees and supporting documents are accounted for.	[ ]

For a financed purchase, ask when the mortgage commitment and any lender recognition agreements are required. Identify documents that depend on the lender or seller so that you can follow up before they hold up submission.

Make the financial statement easy to verify

Each amount should have a clear source. If a brokerage account is listed at its statement balance, use that same balance in the financial summary or explain why an updated figure differs. Show account ownership clearly and follow the application's instructions for joint assets.

For example, two applicants with a joint account containing $180,000 should not present it as two separate $180,000 assets. Identify it as joint and count it once in their combined assets. FirstService Residential's application guidance specifically warns against duplicating joint-account information. [2]

Next, calculate what will remain after the purchase. Suppose you have $900,000 in accessible assets and expect to use $360,000 for the down payment and closing expenses. The starting point for remaining assets is $540,000. If you also plan to spend $80,000 immediately on renovations, your own available cushion falls to $460,000. These hypothetical figures do not establish whether a particular board would approve you.

Ask which assets the building counts toward post-closing liquidity. Retirement funds, restricted stock and private investments may be treated differently from available cash. Keep your own renovation budget separate from the board's reserve calculation so you understand both.

Our REBNY financial statement guide and guide to the cash needed for an NYC purchase explain these distinctions in more detail.

Request letters with clear instructions

Give each writer the building's actual requirements, the correct addressee and a realistic deadline. An employment verification letter and a professional reference can serve different purposes; confirm which is requested.

A useful reference describes what the writer knows firsthand about you. Avoid supplying a script that produces several nearly identical letters. For examples and guidance on choosing writers, see our co-op reference letters guide.

Organize the package for the way it will be reviewed

Many applications use an online portal. Upload documents to the designated sections and check that every PDF opens, is legible and contains the required pages. Confirm how each applicant gives your broker access for review. If the building requires paper copies, follow its specific instructions. FirstService Residential, for example, provides an online process with permissions for applicants and brokers. [2]

If an index is requested or permitted, mirror the building's checklist. A simple order might be application forms, financial summary, supporting statements, income documentation, references, contract and financing documents. Use the building's order when it differs.

Provide a short factual explanation for an item that would otherwise be confusing, such as a recent job change or an unusually large transfer, when requested or appropriate. Keep it relevant to the application and supply the information the building needs to assess it.

Use the designated portal or secure delivery method for sensitive records. Confirm any permitted redactions before removing information needed to verify the application.

Understand the submission and review timetable

Check the contract's deadline for submitting the package and start preparing while financing is underway. Save your submission confirmation and subsequent notices.

For covered applications made on or after July 28, 2026, NYC's Local Law 58 generally requires acknowledgment within 15 days, stating whether the application is complete. If acknowledgment is not provided when due, the application is deemed complete. A decision is generally required within 45 days after acknowledgment of a complete application or the date it is deemed complete. Extensions and documented summer recesses can affect the timetable. [3]

The law excludes certain co-ops, including HDFCs, transactions subject to governmental housing-agency approval and properties with fewer than 10 dwelling units. Have your attorney confirm coverage and calculate the dates for your application. The timetable does not guarantee approval or set the closing date. [3]

Check these details before submitting

The financial summary reconciles to the supporting statements.
Joint assets and the contract deposit have not been counted twice.
Required statement pages, tax schedules and signatures are included.
Income documentation explains your actual compensation or business income.
References satisfy the building's requirements.
Lender and seller documents have been obtained where required.
Fees, delivery instructions and submission deadlines have been confirmed.

Review the final package yourself. You should understand the numbers and be able to explain your plans consistently when the board meets you. Our co-op board interview guide covers that next step.
