Sources of Mortgage Notes

The full supply chain of mortgage notes -- from banks and hedge funds to exchanges, brokers, and the FIXnotes marketplace.

Finding mortgage notes for sale is the number one challenge new investors face. You can master due diligence, build a flawless pricing model, and have capital ready to deploy -- but none of it matters if you cannot find assets to buy. This lesson maps out the full supply chain of mortgage notes, from the institutions that originate them to the channels that bring them to your desk.

The secondary mortgage market is not a single exchange with a ticker symbol. It is a fragmented, relationship-driven ecosystem where loans flow through banks, hedge funds, exchanges, brokers, and individual investors. Each channel has different barriers to entry, deal sizes, and levels of competition. Understanding which channels match your current stage is the first step toward building consistent deal flow.

Banks and Credit Unions

Banks are the original source of most mortgage notes. When a borrower takes out a home loan, the bank originates it -- and when that loan stops performing, the bank needs to get it off its balance sheet. Selling non-performing loans frees up reserves so the bank can issue new loans.

Bank-direct deal flow offers the best quality and the best pricing, but it is the hardest channel to access. Banks want to work with buyers who have a track record, can close reliably, and can handle volume. You will not walk into a community bank on day one and walk out with a pool of NPLs.

What bank deal flow looks like:

  • Pool sizes range from a handful of loans at a community bank to hundreds or thousands at a top-20 institution
  • Data quality is raw -- expect internal codes, non-standard column headers, and abbreviations that require a data dictionary
  • Competition is moderate to low if you can establish a direct relationship, because the bank is not running a public auction
  • Best for intermediate to advanced investors who have closed enough deals to demonstrate reliability

Government-sponsored enterprises -- Fannie Mae, Freddie Mac, and HUD -- are the largest bank-adjacent sellers. Their auction programs move enormous pools (often $10M+) through competitive processes designed for institutional buyers. Individual investors rarely participate directly, but the loans that trade in these programs eventually trickle down through resale.

Hedge Funds and Private Equity

Hedge funds and private equity firms are major participants in the secondary mortgage market. They acquire large pools from banks and GSE auctions, work the assets for a period, and then resell subsets they no longer want to hold.

CharacteristicWhat to Expect
Data qualityHigh -- these are sophisticated sellers who provide clean, enriched tapes
PricingEfficient -- they know what their assets are worth and price accordingly
Deal flowCurated -- you are seeing what they chose not to keep, which means the easiest resolutions have often been cherry-picked
Minimum capitalModerate to high ($25K+)

The advantage of buying from institutional resellers is the quality of information and the smoothness of the transaction. The disadvantage is that you are getting what is left after they have already extracted the best outcomes. Your due diligence needs to account for why these specific loans are being sold.

Loan Exchanges and Online Marketplaces

Online marketplaces -- sometimes called exchanges -- are the most accessible entry point for new note investors. These platforms aggregate listings from multiple sellers and allow buyers to browse individual loans or small pools, submit bids, and close transactions online.

Some platforms run auctions where the highest bid wins after a set window. Others function like classifieds, listing loans at ask prices with room for negotiation. The key advantage is transparency: you can see loan-level data, property details, and sometimes even collateral file documents before you bid.

The disadvantage is competition. Because these platforms are open to all buyers, the most attractive loans attract dozens of bids. Pricing tends to be efficient, meaning sellers extract close to full market value and your margins are thinner.

Start here even if you are not ready to buy. Getting on the email distribution lists for marketplaces and reviewing the listings will accelerate your education. Studying how loans are packaged and priced teaches you market norms before you risk any capital.

Brokers

Brokers are intermediaries who source loans from banks, credit unions, hedge funds, and other asset owners, then market those loans to their buyer network. They are one of the most common entry points for individual note investors.

Active brokers send out regular email distributions -- commonly called tapes -- containing loan data for pools currently available for bidding. Building broker relationships takes time and credibility. Brokers want to work with buyers who can actually close. If you submit bids and then fail to perform, you will stop receiving tapes.

The daisy-chain risk. Not every person who sends you a tape actually owns the loans or has a direct relationship with the seller. A daisy chain occurs when multiple brokers sit between you and the actual asset owner, each adding a layer of markup and a layer of communication delay. The result is inflated pricing, slow execution, and confusion about who actually controls the trade. Lesson 2 covers how to detect and avoid this.

Broker QualitySigns
Legitimate, directCan answer detailed questions about the loans, provides a clear seller identity, has a track record of closed trades
Potential daisy chainVague about the seller, cannot provide collateral images or additional data quickly, pricing seems high relative to the asset quality

The seller typically pays the broker's fee, not the buyer -- but the fee is built into the asking price, so the end cost reflects that overhead.

Individual Investors

The most overlooked source of mortgage notes is other investors. Note investors who acquire pools often resell individual loans that do not fit their criteria. Private individuals who originated seller-financed mortgages may want to cash out. Small-scale real estate investors holding a handful of notes may not even know there is a secondary market for their assets.

Competition for individual investor notes is dramatically lower than for institutional deal flow. Most private sellers have never been approached by a buyer, and the transaction is simpler -- a single note with negotiated pricing rather than a competitive bid. The trade-off is volume: building a private seller pipeline takes consistent marketing effort, and conversion rates are low. This is a long-term strategy.

Reaching these sellers requires direct outreach -- data providers, public records research, and direct mail campaigns. For a deeper dive on these methods, read the blog post on how to find and buy mortgage notes for sale.

How the FIXnotes Marketplace Fits

The FIXnotes marketplace was built to solve the sourcing problem that every new note investor faces. Instead of cold-calling dozens of brokers, signing up for scattered email lists, and hoping someone has product, you can search and bid on assets from vetted sellers in one place.

What makes it different:

  • Aggregated trade desk. Assets from multiple sellers are listed in a single, searchable platform with asset-level data -- UPB, lien position, property details, payment status, and more.
  • Commission-free Buyer's Club. Registered buyers pay no buyer-side commissions. The pricing you see is the pricing you pay.
  • Pre-vetted sellers. FIXnotes screens sellers before they list, reducing the daisy-chain risk and the seller legitimacy concerns that plague other channels.
  • Searchable asset-level data. Filter by state, lien position, property type, UPB range, payment status, and other criteria to match your specific investment parameters.

The marketplace does not replace the other sourcing channels -- it complements them. As your business grows, you will build direct bank relationships, develop broker networks, and attend industry conferences. But for getting started and maintaining a baseline of deal flow, having a single platform with vetted, searchable inventory removes the largest barrier to entry.

Matching Your Source to Your Stage

Not every channel is appropriate at every stage. The key is to match your sourcing strategy to your current capital, experience, and operational capacity.

Investor StagePrimary ChannelsGoal
Beginner (first 1-5 loans)FIXnotes marketplace, online exchanges, small broker listsBuild experience; learn the process end-to-end
Intermediate (5-50 loans)Broker relationships, servicing trade desks, private outreachDevelop repeat deal flow; establish track record
Advanced (50+ loans)Direct bank relationships, institutional conferences, GSE participationScale capital deployment; negotiate exclusive flow

The most resilient note businesses diversify across multiple sourcing channels. Relying on a single broker or marketplace creates concentration risk -- if that source dries up, your pipeline stops. A multi-channel approach ensures you always have opportunities to evaluate.

What Comes Next

Finding a source is only the first step. Before you spend time analyzing loans or money on due diligence, you need to make sure the seller is legitimate, owns what they claim to own, and can deliver clean collateral. The next lesson covers how to vet your loan seller -- the four critical questions that protect you from wasting time and capital on bad counterparties.
