There is a website; http://raidsonline.com/ - that has crime information on many cities. I do not know if Greer participates, as that is a small town (but growing fastj) and the smaller ones tend not to participate in the newer technologies.
Although I am in the Charleston area, I have done business in Greer and know folks who live in or near Greer. It is a delightful town with a strong sense of community. It is between Greenville and Spartanburg, which are fast becoming one due to the development and industry moving in. So far, the growth has been well planned and fairly well maintained. BMW has placed their new transmission plant there, and it is part of a fast growing technology corridor between G'ville and Spartanburg.
It is a beautiful area, in the foothills of the Appalachian mountains, and only an hour from Asheville, NC.
Quality of life is rated quite high, but know that much of it is still rural. Only minutes from Greenville, though!
In working with sales agents, be careful! Find one that will give you information needed, will provide answers to questions you didn't know to ask, and is really interested in meeting your needs, not just in selling you something. Real Estate sales agents in SC are a dime a dozen, and there isn't a high level of professionalism overall. However, there ARE some professional ones. You just have be diligent and use discernment..
