Marked years use a different HUD benchmark than FY 2027, so they are not a like-for-like change.
How much will Section 8 pay for a two-bedroom in ZIP 76831?
Housing authorities set voucher payment standards, normally between 90% and 110% of the FMR. With the county-wide two-bedroom FMR of $1,102, which applies unless the housing authority uses Small Area FMRs, that basic range is $992 to $1,212 a month; under the ZIP-level Small Area FMR of $1,090 it would be $981 to $1,199. The voucher pays the lower of the payment standard or the gross rent, minus the tenant's share, which is usually about 30% of adjusted monthly income. Confirm the local housing authority's current schedule before underwriting.
