A phone call about a mortgage error can disappear into a service log; a properly directed written notice starts federal response duties. A servicer generally must acknowledge a qualified written request, notice of error or request for information within five business days and respond within 30 business days. The address, content and type of problem can change how the clock applies.
The letter must identify the account and the problem
The CFPB’s qualified written request guide says the letter should include the borrower’s name, information that lets the servicer identify the mortgage account and the reasons the borrower believes an error occurred or the information requested. A vague demand to “fix the loan” may not give the servicer enough to investigate.
Useful notices name the disputed payment, fee, escrow entry or payoff amount and attach copies rather than originals. The borrower should state the requested correction and keep the signed letter, enclosures and mailing proof. Account passwords and unnecessary sensitive documents should not be included.

The designated address can control whether the clock starts
A servicer may establish a special address for notices of error and information requests. It can appear on the periodic statement, website or transfer notice. Sending the letter only to a payment address or customer-service office can delay or defeat the federal procedure even if the company eventually receives it.
The CFPB’s mortgage-dispute instructions emphasize using the designated address and labeling the correspondence. Certified mail or another trackable method supplies a delivery date from which business days can be counted.
Five days covers acknowledgment, not resolution
The servicer generally has five business days after receiving a qualifying notice to acknowledge it. That acknowledgment can confirm receipt without deciding whether the borrower is right. The investigation and substantive response generally follow within 30 business days.
In some circumstances the servicer can extend the response period by 15 business days if it notifies the borrower and explains the extension. Certain urgent errors have shorter deadlines, and some requests made close to foreclosure follow special rules. A borrower facing a sale date should not rely on the ordinary 30-day timeline as emergency relief.
The response must explain the result
For a notice of error, the servicer generally must correct the account and notify the borrower or conduct a reasonable investigation and explain why no error was found. For a request for information, it generally must provide the requested material or explain why it is unavailable. A form letter unrelated to the issue may not satisfy those duties.
The formal rule appears in Regulation X section 1024.35 for notices of error, with the related information-request rule in section 1024.36. Comparing the response with the exact issue raised makes it easier to identify omissions.
Payments should usually continue during the dispute
A written notice does not ordinarily suspend the obligation to make scheduled mortgage payments. Stopping payment can create late fees, credit reporting and foreclosure risk unrelated to the disputed amount. Borrowers should continue paying what is undisputed unless a lawyer or servicer gives case-specific written direction.
If the dispute concerns where a payment was applied, bank records and the servicer’s transaction history should be aligned month by month. Escrow errors may require tax or insurance statements. A payoff dispute should include the quoted date because interest and fees can change the amount over time.
A missed deadline creates an escalation record
When the servicer fails to acknowledge or respond, the delivery proof and calendar become central. The borrower can file a CFPB complaint, contact the relevant state regulator or seek housing-counseling and legal help. An imminent foreclosure, bankruptcy or limitations issue warrants prompt professional advice rather than waiting for an ordinary complaint process.
The federal procedure gives borrowers a structured clock, not an automatic victory. A complete letter sent to the correct address generally produces the five-business-day acknowledgment and 30-business-day answer duties in the headline. Precision in the notice is what makes those enforceable dates easier to prove.
Borrowers should count business days from confirmed receipt rather than from the date the letter was written. Federal holidays and weekends do not enter the count, and a servicer’s extension notice can move the ordinary response date. A simple calendar attached to the mailing receipt makes an overdue response visible without guessing.
When the response arrives, it should be compared line by line with the original notice. A servicer may correct one payment issue while leaving an escrow or fee question unanswered. The Regulation X duties attach to the errors and information actually identified, so a complete initial letter produces a clearer final accountability record.
