I use a specialized pool inspector for my inspections that have pools in DFW. Given the potential expense related to them, I would rather give up that extra fee to me, and have clients get a really thorough pool inspection. The guy I use is a retired pool builder. I figure he has forgotten more about pools than I ever knew. I know he routinely saves clients lots of money and has a couple of times had bad enough news to cause the sale not to happen.
Most of the time though he finds $500 - $5000 worth of repairs and give a nice walk-through on what is what and how to work things.
If you are in the Dallas area I am happy to share his info.
