Start with the signed contract, not a generic timeline
NYC contracts do not all use the same financing language or deadline. The standard condominium form presents three financing alternatives in paragraphs 1.21.1 through 1.21.3 and, only when the mortgage commitment contingency option applies, ties the buyer's obligation to issuance of a defined Loan Commitment Letter by a stated Loan Commitment Date. A rider can modify those terms.
A co-op contract has its own financing provisions, definitions, and negotiated riders; buyers should not import the condo form's mechanics into a co-op deal. Ask counsel to identify the controlling provision, contract delivery date, commitment date, requested loan amount and term, required lender type, commitment definition, and any notice or extension procedure. Use the attorney-review guide to organize the handoff without interpreting the clause yourself.
A mortgage contingency is not the same as loan approval or funding
A contract contingency can turn on whether a qualifying commitment letter is issued by a deadline. That is different from final underwriting clearance, satisfaction of every commitment condition, clear to close, or the lender's actual funding at closing.
Under the standard condo form, an offer still conditioned on a lender-satisfactory appraisal is not yet a qualifying Loan Commitment Letter, while conditions concerning the purchaser may remain in a commitment and shift risk to the buyer. Buyers should not decide for themselves whether a lender letter satisfies the signed definition or whether an open condition preserves a contract remedy. Send the complete letter and condition list to counsel promptly, then use the commitment checkpoints for remaining loan work.
Build the deadline tracker on the day the contract is delivered
Record the delivery date used by the contract, the commitment deadline, the scheduled closing date, appraisal milestones, rate-lock dates, and any condo, co-op, board, waiver, or managing-agent deadlines. Use calendar reminders well before the contract date rather than treating the deadline itself as the first review date.
Keep the signed contract and riders, application confirmation, Loan Estimate, appraisal updates, lender emails, document requests, building-review requests, and attorney communications in one file. Preserve dates and full message threads so the professionals can see what happened and when.
Move from preapproval to a complete property-specific application
A preapproval obtained before the buyer selected a property is not a commitment on that apartment. CFPB guidance explains that a Loan Estimate is triggered after the lender receives the buyer's name, income, Social Security number for credit, property address, estimated property value, and requested loan amount. The lender generally provides the Loan Estimate within three business days, but that disclosure is neither loan approval nor a Loan Commitment Letter.
The standard condo form calls for diligent, good-faith application steps and, in its model language, submission of the application, supporting documents, and required fees within five business days after the Delivery Date. The signed contract or rider may change that framework, so buyers should ask counsel which timing and diligence terms govern their transaction.
After choosing a lender, communicate the intent to proceed and provide requested income, asset, insurance, building, and transaction documents promptly. CFPB notes that delayed documents can delay the loan and closing. Keep proof of submission, but do not treat submission alone as proof that underwriting or property review is complete.
Separate borrower review from property and building review
The buyer's income, assets, credit, employment, reserves, and source-of-funds review are only one lane. The lender may also need the appraisal, title information, insurance, contract documents, and property-specific answers.
NYC condos and co-ops can add project or building review. Missing questionnaires, financial statements, insurance materials, litigation information, owner-occupancy data, board approval, recognition-agreement documents, or managing-agent responses can delay a commitment even when the buyer's personal file is strong. Track the owner, last action, and next expected update for every missing item so counsel receives a usable status before the deadline.
Ask for a written lender status before the deadline gets close
Ask the loan officer or processor to state what is complete, what is outstanding, who owns each item, whether the appraisal is acceptable, whether project or building review is complete, and whether the lender expects to issue a commitment before the contract date. Ask again when facts change.
Send the written status and any commitment letter to counsel. The lender can explain its file, but the buyer's attorney should evaluate what that status means under the signed contract. The broker can help coordinate documents and contacts but should not interpret the contingency or draft a legal notice.
Do not improvise an extension or cancellation notice
If a commitment is not ready, ask counsel early whether an extension request, notice, supporting lender documentation, or another step should be considered. The answer depends on the signed language, timing, delivery method, diligence requirements, and transaction facts.
Do not assume that an oral conversation, copied email, lender delay, low appraisal, or pending building document automatically extends the deadline or creates a right to cancel. Do not send a legal notice based on a template from another transaction.
Buyer scenarios
A condo buyer's personal underwriting is nearly complete, but project review is waiting for the managing agent's insurance response. The buyer should document the request history, get written lender status, and send it to counsel before the contingency date rather than waiting for the questionnaire to arrive.
A co-op buyer receives a conditional commitment while board approval and a building item remain open. The buyer should provide the entire commitment to counsel and ask the lender which conditions relate to the buyer, property, building, or closing. A conditional letter should not be summarized from memory.
A low appraisal appears shortly before the deadline. The buyer should ask the lender for the report and status, calculate the potential financing gap, review the low-appraisal response workflow, and route contract-rights and notice questions to counsel before negotiating informally with the seller.
What changes the answer
The answer changes with the contract form and rider, delivery date, loan amount, lender type, commitment definition, appraisal result, borrower conditions, condo or co-op review, board timing, seller response, and any written extension.
This resource is general process education, not legal, mortgage, underwriting, tax, title, or financial advice. It does not decide whether a buyer has complied with the contract, may cancel, should waive a contingency, is entitled to a deposit return, or ultimately obtains financing. Those questions require the signed documents and the appropriate professionals.
