Section 8 Fair Market Value of Rent

[Thomas Visaggio]

I am looking to rent out an apartment in Newark, NJ to a section 8 tenant (my first time). Does anyone know exactly how the fair market rent value is determined? 

Is it done independently by an appraiser - or can I supply them comps directly to support the rent I am requesting?

Lastly - it is a 3 bedroom apartment (although 1 of the bedrooms is smaller and currently does not have a closet). Would this be seen as a 2 bedroom apartment which would lead to a fair market rent value being based off other 2 bedroom apartments in the area although it is being utilized as a 3 bedroom apt?

I look forward to hearing your thoughts!
