Research on delinquency timing can easily overreach. Payment records reflect household circumstances, posting practices, assistance, disputes, legal protections, communication access, and local rules. This protocol limits the question to recorded administrative events and emphasizes resident protections, privacy, and qualified review. It must not be used to automate eviction, deny assistance, or profile residents.
Set an appropriate research question
Ask whether recorded account and communication events can describe time to specified administrative outcomes within a defined portfolio and period. Predefine outcomes such as reconciled payment, approved arrangement, correction, assistance referral, unresolved at cutoff, or transfer to qualified review. Do not treat legal action as a success outcome.
Construct the event timeline
Record charge posting, grace or policy milestones, payment and reversal events, ledger corrections, approved contacts, resident responses, disputes, assistance steps, holds, arrangements, and the study cutoff. Use the policy and law applicable at the time. Distinguish system timestamps from effective dates and preserve superseded entries.
Protect residents and sensitive data
Minimize fields, separate identifiers from analytic records, restrict access, and suppress small groups. Exclude free-text details that are unnecessary for the question. Review fair-housing, consumer-protection, debt-collection, bankruptcy, privacy, and local landlord-tenant implications with qualified advisers before extraction or use.
Address selection and confounding
Contact timing is not randomly assigned. Amount, prior history, channel access, staff workload, disputes, assistance, holidays, policy, and resident circumstances can affect both timing and outcome. Describe these factors when captured, but do not imply statistical adjustment has removed all bias. Unrecorded communication remains an important limitation.
