Advertising for who you want vs Fair Housing Act

[Donald S.]

My first property is in a up and coming area, it's on the verge of nice/bad. I'd like to attract the best tenants possible, but don't know where the fair housing act starts to be an issue. Is it against the fair housing act to advertise a "first responder special"? Or police, firefighter, military, discount? could I post something like "Ask about our specials" and then offer discounts to police etc...?
