Last questions, can't a voucher holder apply to any home of any size in their approved area? 

Depends on the size of the job, but I am a big fan of a draw schedule where the first draw is after the demo phase. 

If any of those are missing, well you've only got a 2 legged table and it's going to be issues. 

I would use all 3 plus look at properties currently available for rent that are similar to what you are trying to comp (3 bedrooms/2 baths; similar condition; size; etc). 

or in the 700's because most people think they have perfect credit.You also have to know occupancy type like primary, vacation, investment, how many units, LTV/CLTV, Term, Fixed or Variable, Prepay or No prepay, Loan size etc.

It is a 6 bedroom and while I see a couple of sales in that 1.6 to 1.8 for 5 or 6 bedroom in that size, that seems to be few and far between.  

For my clients, in every city I am set-up in I have an agent who pulls all the comps and writes up an opinion on the value based on size, area, finishes, market. 

There is no one-size-fits-all for markets and salespeople.

It totally depends upon the size of the STR. 

A nice but rental quality unit gets 1500-1650 regularly in that area depending on the size and finishes.
