RentScope

About

Is your rent overpriced — or too good to be true?

  RentScope shows HUD Fair Market Rents directly on Zillow and Apartments.com listing pages, so you know exactly how any rental compares to the government benchmark before you decide.

  WHAT RENTSCOPE SHOWS YOU
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  📊 Full FMR table — Studio through 4BR for the listing's ZIP code, with your unit size highlighted.

  📍 ZIP-level precision — 38,000+ ZIP codes covered using HUD Small Area FMRs (SAFMR), with county-level fallback for the rest of the country.

  🏷️ Diff % badge — see at a glance whether a listing is at FMR (green), slightly above (amber), or significantly overpriced (red,
  >20% above FMR).

  🎫 Section 8 HCV check — instantly see whether the listing falls within HUD's Housing Choice Voucher payment standard (~110% of FMR). Ideal for voucher holders and housing advocates.

  ⚠️ Fraud signal — listings priced below 50% or 35% of local FMR are flagged as suspiciously low, a common pattern in rental scams.

  🏢 Multi-unit buildings — Apartments.com buildings show a per-floor-plan breakdown (Studio / 1BR / 2BR …) with individual diff% for each unit type.

  🔍 Manual ZIP lookup — check the FMR for any US ZIP code without opening a listing, right from the popup.

  All FMR data comes from the U.S. Department of Housing and Urban Development (HUD FY2025). The data is bundled inside the extension
   — no network requests are made at runtime.
