Are these numbers real ?! Using Section 8 FMR as Rental Comps

[Robert-Lee Pass]

Hey everyone so real quick Ive got a question about Section 8 . First of all what is your thoughts on using the section 8 fair market rent number as the comps for what i can get for a unit , and secondly will section 8 care about a garage or the square footage of the unit ?

I believe sq footage doesn't matter and its only Bed/Bath count that do but what about the garage ?

SECOND : I was doing research on the actual Max allowable rent for a particular county. I am finding numbers that say 1500 across the county and then i see numbers that say something completely different when I go to HUDuser.Gov. I want to believe the data they are showing but the top line they show is actually the zipcode i live in 80817 and its showing 3400 for a 4 bed when a 4 bed here is only 2400 market so I feel like that error means i have to scrutinize the whole data sheet.

If anyone has a second would you mind researching really fast as to what the Max Rent amounts are for Zipcode 81007 3 bed 2 bath (I'm seeing 1500 on some and 1840 on others , but that 1840 is what a new build class A rents for in that neighborhood / Zip. so its got me questioning. 

Thanks everyone .I'm about 2 months out from closing on a duplex . rental comps are currently 1600 a side for one of the units I'm buying .. I'm trying to see if 1500 is the Section 8 amount or 1850 because its right there on my comps of 1600 .
