We can't answer that question for you ... it is a decision that each individual property owner must make themselves.
We can tell you that we have experience with several of the voucher program agencies, specifically the Section 8 Voucher program through Prince Georges County and Saint Marys County, along with the State of Maryland's Department of Health and Mental Hygene Voucher program through Charles County. In each case, the rent due to the landlords is received by us directly from the State of Maryland. There are also inspections that are done by the Voucher Program officials.
One thing that we have found out about the Voucher Programs is that they determine what the monthly rent will be for the property. This seems to be based on their own formula that takes into consideration the comparable rentals in the area, whether or not utilities are included, and the income of the applicant.
