Their floor squeaks badly when they have sex and to top it off my bed shakes with their movement.

The federal Fair Housing Act of 1968 and the federal Fair Housing Act Amendments Act of 1988 prohibit discrimination on the basis of the following criteria (called “protected categories”): race or color; religion; national origin; familial status or age—includes families with children under the age of 18 and pregnant women; disability or handicap, or sex.

In one case, the Seller arranged for a six month free lot rent for his son only later did the new Owner find out the son was also a registered sex offender!  

Prohibited in all states is the refusal to rent because of ethnic background, race, religion, sex, sexual proclivity, age, marital status, or income source. 

For my house, my property manager lets me know the details of the animal, breed,  sex, and size, then I make the decision whether or not to rent to them.I think the bigger issue is the integrity of the tenants.

In fact, any time information is shared regarding any of the seven protected classes: race, color, religion, national origin, sex, disability, and familial status it gets scary quick.  

Doom & gloom sells more than sex.

Yes, as long as you live in the property you can dictate a specific sex.

In my area, that includes the following:Race, Color, Religion, Sex, Familial Status, National Origin, Disability, Military Status, Sexual Orientation, Age, Creed, Marital Status, Gender Identity, Source of Income, Immigration and Citizenship StatusBeing 19 y/o, the tenant is feels that this is unfair treatment based on age.

Sure, they think they're all in love forever, but in reality usually it's just sharing living expenses and free sex.
