Household
Stability Index™
Behavior-first decision intelligence for modern housing providers. HSI turns verified financial and housing signals into an explainable 0–100 stability score with a full audit trail on every recommendation.
Renter screening was built for a world that doesn't exist anymore.
Credit scores were designed to predict how someone manages debt. That is a different question from whether a household will pay rent reliably. When housing decisions ride on the wrong question, qualified renters get filtered out and housing providers absorb avoidable risk.
Credit scores measure debt — not housing stability.
A high credit score can belong to someone who has never paid rent. A lower score can belong to someone who has paid on time for a decade. Neither is a stability signal in isolation.
One financial setback can eliminate qualified renters.
A single hardship event — a medical bill, a job change, a divorce — can suppress a credit file for years, even when the applicant has fully recovered and is paying rent on time now.
Housing providers need better decision tools.
Traditional screening returns opaque scores that are difficult to defend under audit and disconnected from the behavioral signals most closely associated with lease outcomes.
Multiple behavioral signals. One enterprise decision framework.
The Household Stability Index™ combines verified payment history, income adequacy, financial resilience, support systems, and behavioral signals into a single 0–100 score. Every score returns with a category breakdown, machine-readable reason codes, and a plain-English recommendation for the housing provider.
HSI is explainable AI — not a black-box score. Every input, every weight, every model version, and every reason is surfaced on every decision, so operators can defend the outcome and applicants can understand it.
- 5 weighted categories. Payment · Income · Financial · Support · Behavioral
- Machine-readable reason codes. The same tokens shown in-app also appear on the adverse-action report.
- Version-stamped model card. Model version, weight configuration, input hash — reproducible for audit.
- Human-in-the-loop. HSI recommends. Housing providers decide.
From applicant to housing provider in one auditable workflow.
Every step is versioned, timestamped, and stored in the audit trail — so every decision is reproducible weeks or years later.
Consents to data collection; completes intake in the applicant portal.
Income, rent history, and supporting documentation verified from first-party sources.
Payment consistency, recovery patterns, and disclosure behavior evaluated across the 5-category HSI model.
0–100 score computed against HSI v1.1.0 (payment-first). Weights are landlord-configurable within admin bounds.
Category breakdown, top reason codes, supporting evidence, and risk flags — surfaced in the decision panel.
Approve · Conditional · Cosigner · Decline. AI recommends; humans decide.
Reviews recommendation with full audit context; issues final decision and (if declining) an adverse-action-ready report.
Explainable, transparent, and consistent — by design.
These are engineering commitments, not legal or regulatory guarantees. HSI is designed to reduce ad-hoc decision variance and improve auditability compared to opaque credit-only screening.
Explainable AI
Every score exposes its inputs, weights, and reason codes. No opaque outputs — the model behavior is inspectable on every applicant.
Transparent by default
Applicants can request a copy of their HSI report, see the category breakdown, and understand the reason codes attached to any decision.
Consistent scoring
Weights and thresholds are configured once, applied to every applicant equally, and versioned across time so historic decisions remain reproducible.
Reduced bias risk
Protected-class variables are not used as inputs. Housing type is never a penalty. Recovery patterns after documented hardship are rewarded, not punished.
Behavior-first intelligence
Verified payment behavior — among the strongest indicators of the next 12 months of rent — is weighted more heavily than any credit tradeline.
Human authority preserved
HSI recommends. Housing providers decide. No autonomous adverse action, ever.
Designed to sit alongside your existing operator stack.
HSI is built as an interoperable decision layer, not a walled garden. Integrations below are described conceptually — StabilityLogic is actively scoping partnerships and does not claim any active vendor relationship until published.
CRM systems
Bi-directional lead sync with applicant pipelines, tour scheduling, and communication histories so HSI scores travel with the applicant record.
Property Management Systems
Push approved applicants and adverse-action reports into your PMS of record; keep decision context threaded to the lease file.
Bank verification
Consented open-banking connections verify income adequacy and payment behavior — feeding trusted first-party signals into the HSI model.
Applicant portals
White-label intake, consent capture, income verification, and report retrieval — running under your brand or ours.
Future API ecosystem
Score retrieval, applicant intake webhooks, decision events, and PMS/CRM sync — sandbox and production keys, versioned endpoints, signed audit logs.
Enterprise controls
Multi-tenant org isolation, per-property roles, per-decision audit trail, and DPA-ready onboarding for institutional deployments.
Better decisions on both sides of the lease.
For housing providers
- Auditable, defensible decisions on every applicant.
- Approve qualified renters that credit-only screening would filter out.
- Adverse-action-ready reports with consistent reason codes.
- Fair-housing posture is documented and versioned — not ad-hoc.
- Configurable weights within governance bounds — model behavior stays your call.
- Human-in-the-loop by design: HSI recommends, you decide.
For renters
- Verified rent-payment behavior counts — not just credit history.
- Housing type is never a scoring penalty (hotel, subsidized, family placement).
- Recovery after a documented hardship is rewarded, not held against you.
- Request a copy of your HSI report, understand the reasons behind any decision.
- Consent-first data handling — you control what's shared, when, and with whom.
- A path forward: reason codes tell you exactly which signals to strengthen next.
