A lot of landlords feel weary about renting an apartment to a HASA tenant. Don't be. HASA (HIV/AIDS Services Administration) is New York City's resource organization for people who have been diagnosed with HIV/AIDS. They provide housing services including emergency transitional housing, non-emergency housing, rental assistance, and home care and homemaking services.
HIV/AIDS is not airborne nor contagious. It is only transferrable through the exchange of bodily fluids. This means that their medical condition will not affect you or any of the other tenants living in your residence. Sadly, a lot of these clients have been stigmatized and discriminated against for their HIV/AIDS status and have no place to live.
Stand above the rest. Depending on the person's resources, they may be required to pay a portion of the rent or program fees. Since a portion of the tenant's rent comes directly from the government, you are guaranteed to get a portion of your monthly rent (which is much more than you can say for working clients).
