During my long, illustrious career, I have compiled a list of software that I consider essential to researching and creating appraisal reports (SnagIt, Google Earth, etc.); software that promotes safe computing (antivirus and firewall); and software that has saved me on more than one occasion (UndeletePlus and SmartSync). I'm cheap, so I like freeware and the only 2 pieces of softare that cost anything are SmartSync and SnagIt - about $100 total. I pay for these because I haven't found an equivalent free replacement.
I have used all of this software on my own computer and I absolutely guarantee they will work for you too!*
Enjoy.
