Loan Pool

A loan pool is a group of mortgage loans bundled together and offered for sale as a single transaction in the secondary market. Also referred to as a portfolio, a pool is how institutional sellers — banks, hedge funds, government-sponsored enterprises, and specialty servicers — dispose of mortgage assets in bulk. The document describing the loans in a pool is the data tape, and buyers who purchase multiple loans from a pool in a single transaction are known as pool buyers.

How Loan Pools Are Created

Loan pools originate when a lender or loan holder decides to sell a group of assets rather than managing or resolving them individually. Common reasons include:

• Balance sheet management — Banks sell non-performing loans to reduce delinquent assets on their books and meet regulatory capital requirements
• Year-end portfolio cleanup — Institutional sellers frequently release pools in the fourth quarter to close out legacy positions before fiscal year-end reporting
• Loss mitigation strategy — Rather than spending time and money resolving problem loans internally, sellers offload them to investors who specialize in workouts
• Securitization — Performing loans are pooled and sold into mortgage-backed securities, though this market operates separately from the whole-loan note investing space

The seller groups loans into a pool based on shared characteristics — typically lien position, geographic region, performance status, or loan type — then distributes the tape to prospective buyers.

Anatomy of a Loan Pool

A typical pool contains anywhere from five to several hundred loans. Each loan is represented as a row on the data tape with columns of data describing the asset. Pools vary dramatically in size and composition depending on the seller:

How Note Investors Work with Pools

Receiving and Filtering the Tape

When a seller distributes a pool, the buyer receives the data tape — a spreadsheet listing every loan with its key data fields: UPB, lien position, property address, borrower name, payment history, and other loan-level details. The buyer's first task is filtering the tape against their buy box — the set of criteria that defines what they will and will not purchase.

On a 100-loan tape, a disciplined investor might eliminate 80–90% of the loans in the first pass based on geography, lien position, UPB range, delinquency depth, or property type. The surviving loans move into deeper analysis.

Bidding on Pools

Pool purchases use loan-level pricing even when the transaction closes as a single bulk deal. The buyer submits a bid on each individual loan they want to acquire, and the total pool price is the sum of the accepted loan-level offers. Some sellers require bids on the entire pool (all-or-nothing), while others allow cherry-picking — selecting only the assets that meet the buyer's criteria.

The bidding process typically follows this sequence:

1. Indicative bid — a preliminary, non-binding offer based on tape-level analysis
2. Due diligence period — the buyer reviews collateral files, orders title searches, BPOs, and credit reports
3. Final bid — adjusted pricing based on DD findings, with specific loans repriced, removed, or confirmed
4. LPSA — the loan purchase sale agreement formalizes the transaction terms, representations, and warranties

Bulk Due Diligence

Analyzing a pool requires a different operational approach than evaluating a single asset. With dozens or hundreds of loans to review, investors use standardized intake templates, bulk vendor orders (credit reports through services like CoreLogic Credco, title data through ProTitle USA), and systematic filtering processes to move efficiently from raw tape to final bid.

The cost structure scales differently at the pool level. First lien due diligence runs $250–$500 per asset, while junior lien DD runs $50–$200 per asset. On a 50-loan pool, those costs add up quickly — which is why experienced pool buyers apply aggressive first-pass filters to avoid spending DD dollars on assets they will ultimately reject.

Pool Pricing Dynamics

Buying from a pool typically provides better pricing than purchasing individual loans on the retail market. Sellers offer volume discounts to pool buyers because:

• Operational efficiency — selling 50 loans in one transaction is cheaper than managing 50 separate sales
• Speed — pool buyers can close faster, which matters to institutional sellers with regulatory or reporting deadlines
• Certainty — a committed pool buyer who will take multiple assets is more valuable than a retail buyer who may back out

The trade-off is that pool buyers must commit to analyzing and closing on a larger number of assets, absorbing the DD costs and operational complexity that comes with bulk acquisition. This is why pool buying favors investors who have established servicer relationships, efficient DD workflows, and sufficient capital to deploy across multiple assets simultaneously.

Pools vs. Individual Loan Purchases

Most note investors start by purchasing individual loans through retail marketplaces and brokers, then graduate to pool purchases as their capital, deal flow, and operational systems mature. The transition from retail to pool buying is one of the key inflection points in scaling a note investing business.
