Though your questions are good ones, I cannot answer them. They both relate to laws on Fair Housing and no matter how they are answered, they can be construed as discriminatory and any realtor that did answer could be subject to being fined, jail and loosing their license.

With regard to zip codes, depending on the county they are located in, most county web sites outline the demographics, weather, schools, income levels, etc.
