How these numbers are calculated
- Voucher rent is the HUD FY2027 2-bedroom Small Area Fair Market Rent (SAFMR) where it applies, otherwise the county or metro Fair Market Rent. This is the basis housing authorities use to set payment standards, typically 90 to 110 percent of it, and it is a gross rent that includes a utility allowance.
- Typical market rent is the Zillow Observed Rent Index (ZORI) for the ZIP code as of September 2026, a smoothed measure of asking rents across all home types and sizes. Rent data provided by Zillow Research.
- Premium compares the 2-bedroom voucher rent against that blended market figure, which is the conservative comparison. Premiums for 3 and 4 bedroom homes are often larger.
- The premium is a screening signal, not a guarantee. Housing authorities run a rent reasonableness review against unassisted comparables before approving any contract rent, and the payment standard is a ceiling, not an entitlement. Always verify with the local housing authority.
