To advertise your unit for rent with the HCV program, submit the Listing Form via email, fax or mail. The Northern Virginia Association of Realtors provides a full library of free forms, which are reviewed and updated regularly, for all members.Don't waste time printing out the contract, signing manually and then scanning back in as a pdf. The form may be in an electronic format on a computer or in paper form. Agent processed changes DO NOT need to be sent to the CRAAR office.
