Hitting the bullseye is one way to avoid ROVs. It's not the only way. Delivering a well written, fully supported appraisal also works. One of the requirements for that is doing the work. To the best of my recollection, in the relatively few ROVs I've gotten, I've never been given a sale that had not already been considered and was safely tucked away in my work file.
I've worked ROVs from both sides, and imo, most of the time, the Homeowner/Realtor/Loan Officer knows that you did a good job. What they don't know is how willing you are to bend over when they complain.
