The FY 2027 Boston-Cambridge-Quincy, MA-NH HUD Metro FMR Area Small Area FMRs

The following are the steps used to calculate the 2-Bedroom Small Area Fair Market Rent of $2,650 for ZIP Code 01431.

  1. Evaluate the reliability of the current 5-year ACS Adjusted Standard Quality (ASQ) 40th percentile 2-Bedroom gross rent. If the estimate has a margin of error ratio of less than 50% and at least one hundred survey case, use this as the ZCTA base rent for the SAFMR for the current year.
  2. If the 2-Bedroom rent is not reliable, evaluate the 1-Bedroom gross rent. If this estimate is reliable, convert it to a 2-Bedroom rent using the appropriate bedroom ratio of the parent HUD metropolitan area or relevant non-metropolitan county.
  3. If the 2 and 1-Bedroom rents are not reliable, evaluate the 3-Bedroom gross rent. If this estimate is reliable, convert it to a 2-Bedroom rent using the appropriate bedroom ratio of the parent HUD metropolitan area or relevant non-metropolitan county.
  4. Repeat the above three steps for the previous two ACS years. If a ZIP code has reliable 2-Bedroom equivalent rents in at least two or the three ACS years, update the non-current year ACS estimates for inflation, and take the average of the reliable estimates as the base rent for FY2027.
  5. Calculate a FY2027 Small Area Fair Market Rent by multiplying this base rent by the recent mover factor, the gross rent inflation update factor, and the forecasted trend factor.
  6. If the ZIP code does not have a reliable base rent, evaluate the quality of its 5-year ACS Adjusted Standard Quality (ASQ) median all bedroom gross rent for the previous three ACS years. If at least two of these three estimates are reliable, calculate ratios of the ZIP code median gross rent estimate to that of the ZIP code's parent HUD metropolitan area or relevant non-metropolitan county. Take the average of these ratios. If the ZIP code does not have reliable ZIP code median gross rents, examine the reliability of the ZIP code's parent county. If at least two of these three estimates are reliable, calculate ratios of the county median gross rent estimate to that of the county's parent HUD metropolitan area or relevant non-metropolitan county. If county level estimates are not reliable, set the ratio to 1.
  7. If necessary, apply the ZIP code rent ratio to the FY2027 2-Bedroom Fair Market Rent for the ZIP code's parent HUD metropolitan area or non-metropolitan county.
  8. Ensure that the 2-Bedroom SAFMR does not exceed 150% of the parent HUD metropolitan FMR or relevant non metropolitan county FMR.
  9. Ensure that the 2-Bedroom SAFMR is not lower than the ZIP code's parent state minimum FMR.
  10. Calculate SAFMRs for other bedroom sizes using the bedroom ratios for the ZIP code's parent HUD metropolitan area or non-metropolitan county.
  11. Ensure that the SAFMRs do not fall below the appropriate 90% floor.

The remainder of this page provides complete documentation of the development of the Final FY 2027 2 Bedroom Small Area Fair Market Rent (FMR) for 01431 within the Boston-Cambridge-Quincy, MA-NH HUD Metro FMR Area.

  1. Evaluate the bedroom size estimates of 40th percentile gross rent for 01431.

  2. Since 01431 does not have a useable bedroom base rent, its SAFMR will be based on a rent ratio.

  3. ZCTA level estimates of median gross rent will be used as the numerator for the small area rent ratio provided at least 2 of the most recent 3 estimates from 5-Year ACS samples are statistically reliable. Reliability is determined by calculating a margin of error ratio for each estimate. If the margin of error is less than 50% of the estimate, then it is considered reliable.

    2024 $1,500 $408 $408 / $1,500 = 0.27 Yes $2,293 $1,500 / $2,293 = 0.654
    2023 $1,278 $754 $754 / $1,278 = 0.59 No $2,205 $1,278 / $2,205 = 0.58
    2022 $997 $892 $892 / $997 = 0.89 No $2,074 $997 / $2,074 = 0.481

  4. Because the ZCTA does not have a local rent estimate, its Small Area FMR is based on the average of its neighbors, if applicable.

    Neighboring ZIP Neighboring ZIP SAFMR Weight
    01420 $1,790 6
    01462 $2,840 1
    01474 $3,400 4
    03048 $1,610 2

    The average of the neighboring ZCTA SAFMRs is $2,350

  5. Ensure that the 2 Bedroom Small Area FMR does not fall below the State Minimum FMR.
