Debexpert (debexpert.com) is an auction platform where sellers list debt portfolios — including real estate notes, consumer debt, and medical debt — and approved buyers compete in timed auctions. It is built mostly around portfolio-scale transactions. FIXnotes, by contrast, is a marketplace for buying individual residential mortgage notes with open browsing and per-note underwriting data.

How do Debexpert auctions work?

Sellers upload a debt portfolio, and Debexpert markets it to its network of approved buyers, who bid in one of four auction formats (English, Dutch, sealed-bid and hybrid). As of October 2026, Debexpert's site cites 14–21 days on average from submission to payment. FIXnotes uses a direct offer-and-counter workflow on individual notes instead of timed portfolio auctions.

Is Debexpert free to browse?

Partly. As of October 2026, Debexpert's auction calendar and summaries of past portfolios are public, while data files, due diligence and bidding require approved registration. FIXnotes' listings and asset pages can be viewed without an account.

What does Debexpert offer that FIXnotes doesn't?

Debexpert handles portfolio-scale auctions across multiple debt classes — consumer, medical, auto, and other receivables alongside real estate notes — with seller-side tools including a built-in CRM for post-sale management and iOS and Android apps. Sellers disposing of large mixed portfolios, or buyers operating at pool scale, will find that infrastructure on Debexpert. FIXnotes focuses on individual residential mortgage notes.

Which platform is better for buying mortgage notes?

They serve different transactions. Debexpert is strongest for portfolio auctions with approved-buyer access, which fits institutional or bulk buyers. FIXnotes is built for buyers underwriting individual residential notes, with buyer qualification, a free deal calculator and a free Knowledge Base included.
