A wise man one said, that the neighborhood the home resides in is what really sells the home. Well, pretty much every real estate agent will tell you that, but it's still true. Home and property values go up and down for many factors, but more predominantly because of the surrounding houses and aspects of the neighborhood.
It's a high pressure situation buying a home, and there are plenty of things to look at and for when researching the area. Security obviously should be a priority, as are things that you need to be nearby (schools, grocery stores, restaurants, etc). We all love our coffee right? If you're in a large area I bet there is a Starbucks nearby.
Take a look at the house and neighborhood at night. It's one common thing that doesn't always cross the mind of a potential buyer. You never know what might be different once the sun goes down.
Whether it's Wimberley real estate or anywhere else, it's important to take your time and do the proper research. Not only on the home itself, but everything close by. How good are the testing scores at schools your kids may go to? Are you sure you can see yourself in the home for at least the next five to seven years?
