Self‑employed renters blocked — verified income proof for landlords (50–100 chars)

Many landlords and property managers are increasingly faced with qualified applicants who cannot present traditional W‑2 pay stubs, leaving self‑employed renters blocked from leasing despite steady cash flow; this friction slows leasing cycles, increases vacancy costs and creates manual work for teams that oversee roughly 50 million rental units in the U.S. The problem is acute for mid‑market and institutional owners who need standardized, auditable income evidence at scale rather than ad‑hoc document collection and subjective underwriting. You could build a B2B SaaS verification platform that ingests tenant‑consented bank and business accounts via open‑banking APIs, standardizes transaction analysis, pulls invoices/1099s/tax returns, and outputs a time‑series income score plus a signed, landlord‑facing verification report and API endpoint for property management systems. Pricing could combine per‑verification fees and a subscription per unit (targeting an $80/year average revenue per unit to align with a $4.0B market opportunity), while features would include machine‑readable audit trails, fraud checks, and configurable underwriting rules for different owner risk tolerances. The timing is favorable: self‑employment and gig income are growing, open‑banking connectors make automated access feasible, and leasing workflows are increasingly digitized, which together lift a previously structural barrier to product adoption. To stand out you must demonstrate materially better predictive power on rental performance for variable income earners, prioritize privacy and compliance, and lock in integrations with 2–3 major property management platforms or regional managers early; the primary challenges will be landlord trust, initial data sparsity, and regulatory/privacy complexity even though the market score is high (92/100) and revenue potential strong (85/100).
