Notice of Error or Request for Information
Mr. Cooper
P.O. Box 619098
Dallas, TX 75261
A Notice of Error or Request for Information should be clearly labeled and sent to the specifically designated address. Sending it to the regular payment address may delay its handling.
Borrowers should verify all addresses through the official Contact Us page before mailing.
Payments, Payoffs, and Escrow Assistance
Borrowers can generally make payments through:
- The online account
- AutoPay
- The automated telephone system
- Approved third-party payment services
Keep payment confirmation and allow sufficient delivery time for mailed checks.
Eligible borrowers can request a payoff quote through their online account or automated telephone system. A payoff quote includes more than the principal balance and may account for interest, fees, escrow, and other amounts due through a specified date.
Preparation and expedited-delivery fees may apply to some payoff statements.
For escrow concerns, review the most recent escrow analysis before contacting Customer Service. Changes in property taxes, insurance premiums, required reserves, or shortages can affect the monthly payment.
Mortgage Assistance and Foreclosure Concerns
Borrowers experiencing financial hardship should contact Mr. Cooper promptly and ask about available mortgage-assistance options.
Possible options depend on the loan and may include:
- Repayment plans
- Forbearance
- Payment deferral
- Loan modification
- Short sale
- Deed-in-lieu review
- Disaster assistance
Approval is not guaranteed. Borrowers should submit complete documents by the stated deadlines and continue monitoring the secure Message Center.
A general complaint does not automatically stop foreclosure, extend an appeal deadline, or suspend contractual payment obligations. Borrowers facing foreclosure should consider contacting a HUD-approved housing counselor or qualified attorney promptly.
