What has to happen when your mortgage servicing gets sold, explained

Your loan being sold doesn't change your rate, balance, or terms — but the company you send your payment to can change, sometimes more than once. Regulation X spells out exactly who has to tell you, how far in advance, and what protects you if the timing goes wrong.

Two servicers, two notices, one transaction

Under 12 CFR § 1024.33, a servicing transfer involves a transferor servicer (the one giving it up) and a transferee servicer (the one taking it over) — and RESPA's Regulation X requires each of them to send the borrower a written notice of transfer. The transferor's notice has to go out no less than 15 days before the transfer's effective date; the transferee's notice has to go out no more than 15 days after it. The two servicers can also send a single combined notice instead of two separate ones, as long as it goes out at least 15 days before the effective date — a common practice when the transfer is planned rather than triggered by a servicer failure.

The exception: transfers forced by servicer trouble

When a transfer happens because the old servicer's contract was terminated for cause, or because the servicer (or its parent) entered bankruptcy or FDIC conservatorship/receivership, the notice deadline stretches to 30 days after the effective date instead of the tighter combined-notice window — recognizing that an orderly 15-day advance notice isn't realistic when the transfer itself is a symptom of the servicer failing.

The 60-day grace period that actually protects you

The rule most borrowers never hear about until they need it: for 60 days beginning on a transfer's effective date, a new servicer cannot treat a payment as late, and cannot charge a late fee or report you delinquent, solely because you mailed the payment to the old servicer instead of the new one. This is a real, mandatory grace period under § 1024.33(c)(2) and § 1024.39 — not a courtesy some servicers choose to extend. If a payment sent to the wrong address during that 60-day window gets treated as late anyway, that's a compliance failure worth raising directly with the new servicer, and escalating to the CFPB or your state regulator if it isn't fixed (see how to file a complaint).

What this rule does and doesn't cover

These notice and grace-period requirements apply to the transfer of servicing rights — who collects your payment and manages your escrow — not to a sale of the underlying loan's ownership, which can happen without any change in servicer at all and carries no equivalent notice requirement of its own. Federal compliance here also preempts state law: a state can't impose its own separate borrower-notice timing requirement on top of Regulation X's. It also has nothing to do with what happens inside your escrow account once a new servicer takes over — see our escrow analysis explainer for that.
