this is what i found...not sure if it answers the question... so like i said i say yes i would be open to it but then find a legit excuse as to why you went with some one else... its hard these days as people try to trap and sue you for so many things...
hopefully some one who knows better will chime in...
Q: Are landlords required to lease to people who have Housing Authority vouchers?
A: No. As a landlord, you have the freedom to rent to whoever you like, so long as you are not discriminating against potential tenants based on color, race, religion, sex, familial status or national origin. The Housing Authority does not require landlords to house families involved in the program, nor does it screen families. Rather, the Housing Authority only determines program eligibility and leaves the responsibility of screening families up to the landlord. So long as you require all potential tenants to complete an application and screening process, you are fully within your rights as a landlord.
