John and Jane Doe's report is basically written. I have a template that I use that has been slowly built and improved over the past projects. It's a fine start but still requires a fair amount of custom writing, since each house has enough unique issues that need to be addressed.  There's report software out there such as Recurve's, EAI, or BizEE, but none have that personal touch that comes from a written report.  So here's some items from the report:
