Washington DC HCVP Program Rents

[Brendan August]

I am currently under contract for a 4 bedroom 3 bath home in Columbia Heights that I plan to live in for a year with roommates and then look for HCVP voucher holders to rent the entire home in the 2nd year. When running my numbers is it safe to just use the approved HCVP rents for a 4 bedroom in that neighborhood or is that just the upper limit that the rent could be and I should expect to receive less? 

The home is nice and has central AC, washer/dryer and decent finishes. I'm not sure if this has an impact on the HCVP rent or it is just the number of bedrooms. 

Any advice or experiences people have had would be great. Thanks!
