In my state, there is no requirement to disclose a SP in the vicinity. There is no way to prove the seller or his/her agent knew.

In my state, buyer agents have had board troubles arizing from disclosing such information because it potentially stigmitizes a property.

And generally speaking, local agents know and don't show the property, which tends to be listed with an out of area agent.

Am I the only one who thinks one day the Fair Housing Act will be ammended to create protection for SP? Nothing will surprise me.
