All of those people have given you great resources to use, to check out an area's crime statistics.
What they haven't done, completely, I feel, is answer the question of WHY Realtors and Real Estate Agents cannot tell you if an area is "Safe".
Crime is a very random occurrence & Safe is a relative term. For example:
What if you were told an area was "safe" and then you become a victim of a crime in this area, even if you are the first, ever?
What if you were told an area was "unsafe" and you don't buy, and crime takes a holiday and you end up paying twice as much somewhere else?
What if you were the seller of a property, and had never had a problem, due to alarms or coincidence, etc. but no one buys your home, because the area has a bad reputation?
What if you were a buyer of a home, and an agent tells you that the area is 'unsafe', just to steer you to another, more expensive listing or area?
Don't let someone else make that determination for you. Follow those examples they spoke of below:
Check the history using those resources on-line.
Talk to your potential future neighbors. (some neighborhoods have bloggers)
Drive the area at various times of day or night.
Speak to local police for a professional opinion, (although some police departments have taken to avoiding answering those questions for liability reasons)
And, when using those resources, do a few more things.
Compare the crime statistics looking at population density.
<Life in an urban area will sometimes have higher crime rates than other, less densely populated areas, Very little car theft on Mount Everest, for instance. ;) >
Compare the crime statistics with an area you are already familiar with and comfortable with.
Raw data can be scary, and most people have no idea how much crime is going on, even in the areas they have lived in for years. Once you know what its like in a "baseline" area, you can determine, for yourself, whether an area is "Safe" or not, for yourself.
