You may be dead set on a particular neighborhood, but keep an open mind and ask your realtor for suggestions. Unless you have previously lived in the area, no one can gauge 100% of their living experience based on online research.
Remember that real estate agents are not only there to help you buy a home, but to also truly advise you every step of the way. They know the area better than most and know common pitfalls that buyers make. Ask your real estate agent about the proposed area or if they can suggest other areas near you. By doing this, you may find a hidden gem or save thousands on your rent or mortgage.
