Seasoning

Seasoning describes how long a mortgage loan has been in existence since its origination date, and it is one of the most fundamental data points note investors use when evaluating a loan on a tape. A loan with 24 months of seasoning has been active for two years; one with 120 months has been on the books for a decade. In the secondary note market, seasoning matters because it provides a track record — a longer payment history gives buyers more data to evaluate borrower behavior, while the absence of payments over an extended period raises questions about collectability and statute of limitations exposure.

How Seasoning Affects Different Loan Types

Seasoning carries different implications depending on the loan's payment status:

For re-performing loans specifically, buyers typically want to see a minimum seasoning threshold before paying a meaningful premium over NPL pricing. Industry norms vary, but the general benchmarks are:

• 3-6 months of re-performance: Still priced near NPL levels; high re-default risk
• 6-12 months: Moderate confidence; pricing begins to improve
• 12-24 months: Strong seasoning; the loan begins to trade closer to performing note pricing
• 24+ months: Fully seasoned re-performer; investors treat these nearly the same as performing loans

Seasoning and Statute of Limitations Risk

For non-performing loans that have been delinquent for years, seasoning becomes a liability rather than an asset. Every state has a statute of limitations governing how long a lender can enforce a mortgage debt after default. If a loan has been non-performing for eight years in a state with a six-year statute, the note holder may have lost the right to foreclose or sue on the promissory note.

When reviewing a data tape, compare the loan's last payment date and default date against the applicable state statute. Watch for these red flags:

• Last payment date more than 4-5 years ago (approaching limits in many states)
• No acceleration letter on file — unclear when the clock started
• Prior servicer lost records of partial payments that might have reset the clock
• Loan has been transferred multiple times without any enforcement action

Seasoning on the Data Tape

On a typical loan tape, seasoning-related fields include the origination date, first payment date, last payment date, next due date, and months delinquent. The difference between the origination date and today gives you the loan's total seasoning. The difference between the last payment date and today tells you how long the loan has been non-performing.

Experienced investors develop quick filters around seasoning when screening loan pools. A pool full of recently originated loans that defaulted quickly may signal underwriting problems. A pool of long-seasoned performers with years of clean payment history is a different risk profile entirely. Context matters — seasoning is never evaluated in isolation, but rather alongside unpaid principal balance, lien position, property value, and borrower payment behavior to build a complete picture of the asset.
