HUD HCV Guidebook § 3.1.1

It is important for a PHA to understand what affects rents in its local rental housing market. In some markets,
a feature might affect the rent, but in another it might only affect the desirability of the unit; this desirable
feature might result in the unit renting faster but not in a higher rent.
Not all of the factors that HUD requires PHAs to review have the same effect on rents, and there is
considerable variation on what is important from market to market. However, the three most important
factors in explaining differences in rents are:
          Location of the unit;
          Number of bedrooms in the unit; and
          Type of unit (e.g., high rise, garden apartment, duplex, single family home).
PHAs are not required to quantifiably document or consider all nine factors discussed in Section 2.2, as such
a method is unnecessary and time-consuming. PHAs should take a common-sense approach to valuing a unit
based on these factors.
