Fair Market Rent Calculation Methodology
Show/Hide Methodology Narrative
Fair Market Rents for metropolitan areas and nonmetropolitan FMR areas are developed as follows:
20102014 5year American Community Survey (ACS) estimates of 2bedroom adjusted standard quality gross rents calculated for each FMR area are used as the new basis for FY2017 provided the estimate is statistically reliable. For FY2017, the test for reliability is whether the margin of error for the estimate is less than 50% of the estimate itself.
If an area does not have a reliable 20102014 5year, HUD checks whether the area has had at least minimally reliable estimate in any of the past 3 years, or estimates that meet the 50% margin or error test described above. If so, the FY2017 base rent is the average of the inflated ACS estimates.
If an area has not had a minimally reliable estimate in the past 3 years, the estimate State for the area's corresponding metropolitan area (if applicable) or State nonmetropolitan area is used as the basis for FY2017.
HUD calculates a recent mover adjustment factor by comparing a 2014 1year 40th percentile recent mover 2bedroom rent to the 20102014 5year 40th percentile adjusted standard quality gross rent. If either the recent mover and nonrecent mover rent estimates are not reliable, HUD uses the recent mover adjustment for a larger geography. For metropolitan areas, the order of geographies examined is: FMR Area, Entire Metropolitan Area (for Metropolitan SubAreas), State Metropolitan Portion, Entire State, and Entire US; for nonmetropolitan areas, the order of geographies examined is: FMR Area, State NonMetropolitan Portion, Entire State, and Entire US. The recent mover adjustment factor is floored at one.
HUD calculates the appropriate recent mover adjustment factor between the 5year data and the 1year data and applies this to the 5year base rent estimate.
Rents are calculated as of 2015 using the relevant (regional or local) change in gross rent Consumer Price Index (CPI) from annual 2014 to annual 2015.
All estimates are then inflated from 2015 to FY2017 using a national trend factor based on the forecast of gross rent changes through FY2017.
FY2017 FMRs are then compared to a State minimum rent, and any area whose preliminary FMR falls below this value is raised to the level of the State minimum.

 The calculation of the relevant RecentMover Adjustment Factor for OlympiaTumwater, WA MSA is as follows:

The calculation of the relevant CPI Update Factors for OlympiaTumwater, WA MSA is as follows:
HUD updates the 2014 intermediate rent with the ratio of the annual 2015 local or regional CPI to the annual 2014 local or regional CPI to establish rents as of 2015.
Update Factor Type CPI Update Factor 1.0519 Local CPI 
The calculation of the Trend Factor is as follows: HUD forecasts the change in national gross rents from 2015 to 2017. This makes Fair Market Rents "as of" FY2017.
National Trend Factor 1.0531  The FY 2017 2Bedroom Fair Market Rent for OlympiaTumwater, WA MSA is calculated as follows:
Area ACS_{2014} 5Year Estimate RecentMover Adjustment Factor Annual 2014 to 2015 CPI Adjustment Trending 1.0531 to FY2017 FY 2017 2Bedroom FMR OlympiaTumwater, WA MSA $931 1.039 1.0519 1.0531 $931 * 1.039 * 1.0519 * 1.0531=$1,071 
In keeping with HUD policy, the preliminary FY 2017 FMR is checked to ensure that is does not fall below the state minimum.

Final FY 2017 FMRs By Unit Bedrooms  

Efficiency  OneBedroom  TwoBedroom  ThreeBedroom  FourBedroom  
Final FY 2017 FMR  $784  $866  $1,071  $1,559  $1,887 
The FMRs for unit sizes larger than four bedrooms are calculated by adding 15 percent to the four bedroom FMR, for each extra bedroom. For example, the FMR for a five bedroom unit is 1.15 times the four bedroom FMR, and the FMR for a six bedroom unit is 1.30 times the four bedroom FMR. FMRs for singleroom occupancy units are 0.75 times the zero bedroom (efficiency) FMR.
