I see that you are interesrted in by some kind of property; but the question is, where is the property so we can properly advise you. Since we have to consider several elements within the proposed purchase. Furthermore, the sales /buying proceses is very involved and the advise that you need only a knowlegeable broker/agent will most likely put toghether that kind of info for you(since he has been retained) like:
Area Comp( true Market Value)
Crime Statistic and so forth. I hope my answer will give you an insight into the situation. Thanks.
