RentWise — Rental Qualification Platform

Most rental platforms solve discovery. They don't solve approval confidence. Renters apply to places they won't qualify for. Landlords review applicants who were never a good fit.

Problem

Most rental platforms solve visibility, not decision quality.

Most rental platforms solve visibility, not decision quality. Renters apply to properties they won't qualify for.

Landlords receive applications that were never a good fit. Both sides waste time and energy on bad matches.

The core problem wasn't finding listings — it was knowing which ones were actually worth pursuing.

Qualification logic needed to come before the application, not after rejection.

What I Built

6 key contributions that defined the build

  • Built the detailed renter onboarding flow capturing income, household size, guarantors, pets, vehicles, and rental history — mirroring what landlords actually evaluate.
  • Implemented hard-requirement filtering that removes clearly mismatched listings before a renter considers applying.
  • Developed a multi-factor scoring layer that ranks listings by fit strength, not just availability.
  • Integrated third-party background check APIs for credit, criminal, and screening data.
  • Designed the match-focused dashboard showing strongest property opportunities with qualification visibility.
  • Collaborated directly with founders on qualification logic, scoring weights, and product flow validation.

Key Decisions

Tradeoffs and approaches that shaped the final outcome

Challenge

Qualification filtering that's too aggressive breaks trust; too lenient removes the product's core value — the right calibration required real business judgment, not just technical rules.

Approach

Modeled qualification rules after real landlord criteria so filtering felt accurate and fair — users saw it as helpful, not restrictive.

Challenge

Handling sensitive personal data (SSN, background check inputs) responsibly without building internal screening infrastructure.

Approach

Delegated screening data to third-party background check APIs, keeping sensitive information outside internal storage and reducing compliance exposure.

Impact

Transformed the product from a listing marketplace into a qualification engine — a genuine competitive differentiator that neither Zillow nor Apartments.

  • Transformed the product from a listing marketplace into a qualification engine — a genuine competitive differentiator that neither Zillow nor Apartments.com offered.
  • Reduced wasted application effort for renters and improved applicant lead quality for landlords on both sides of the match.
