Frequently Asked Questions
- What is the best mortgage note marketplace for buyers?
- It depends on what you buy. FIXnotes lists individual residential mortgage notes, most of them non-performing, with buyer qualification, a free Knowledge Base and a free bi-weekly Community Chat. Paperstac runs a public listing marketplace that shows asking prices and yields, with an online closing workflow. Debexpert sells debt portfolios, including real estate notes, through timed auctions.
- Which note platforms are free to browse?
- FIXnotes and Paperstac both show their active listings to visitors without an account. Debexpert publishes its auction calendar and summaries of past portfolios, while data files and bidding require approved registration. Watermark Exchange showed a public listing index with note detail behind a login as of June 2026.
- What is the difference between FIXnotes and Paperstac?
- Paperstac shows an asking price and computed yield metrics on every public listing and runs closings online with escrow, notary and a collateral audit. FIXnotes focuses on non-performing residential notes: buyers qualify before making offers, an accepted buyer gets a 3-week exclusive due diligence window, and the Knowledge Base and Community Chat are free.
- Do any note platforms offer educational resources?
- Yes. FIXnotes publishes a free Knowledge Base and runs a free bi-weekly Community Chat for logged-in members. Paperstac publishes a free help center, a blog and a weekly podcast, and sells a paid Academy that includes a weekly live call. Debexpert publishes a blog aimed mostly at sellers.
- Which note marketplaces have shut down?
- As of October 2026, NotesDirect (inactive since 2024; its domain redirects to NoteSchool), LoanMLS (its domain redirects to a lender-matching site) and NoteTrader (a parked domain) no longer run note marketplaces.
- What websites do note brokers use?
- Brokers can look at the same note marketplaces buyers use. The ones compared on this page are listed under "Note Broker Websites" with what each is; each platform's own comparison page gives the date we last checked it and any availability note. FIXnotes is a marketplace for non-performing notes; people who want to place notes with buyers rather than buy them start with the Broker Bundle: the Accelerator program, twelve months of the FIXnotes platform and a 1:1 strategy session.
