For an Adjustable-Rate Mortgage (ARM), specific disclosures must be provided to the borrower within three business days of receiving a completed loan application. These disclosures are required under TILA (Truth in Lending Act) and include detailed information about the loan’s terms, how the interest rate can change, and what potential payment increases might occur over time.

The Loan Estimate (LE), which includes ARM-specific information, must be provided within this timeframe to ensure the borrower understands the adjustable nature of the loan before proceeding further in the process.

Other options like at closing or when a loan is locked in are incorrect, as disclosures must be provided much earlier in the process.
