I just posted and asked the same question, you can search on my name. Above and beyond a home inspection, I had a pool inspection, separate leak detection company do an inspection, and separate HVAC and plumbing inspections. The pool inspection was fairly basic. The sellers in NW Arkansas were very accommodating and while they had already closed the pool and pool cabana and winterized, they had the pool opened and operating, including the heater. The pool inspector operated all the equipment, noting what was either out of date, single speed pump, and at end of life but still "working" heater. I asked about removing, replacing some equipment, adding SWG, and inspector noted that there was room, plumbing needed cleaning up a bit, lots of 90s. I asked about a check valve prior heater, not existing but could be added. I also asked about bonding, grounding, GFCIs, dedicated circuit breakers. The most valuable thing I did was take pictures of the equipment pad layout and detail shots of all the equipment labels. TFP members stepped up with telling what each piece did, directional arrows, and lots of advice on what to look for, what to update with and replace. The leak detection company was very thorough. He dived and was in the pool more than an house. They area is a sellers market. I had this done so I knew what I was getting into $ wise when I took over. One thing, if they tell you something, make sure they put in a written report, especially if you think you want to use it for credit on the price of the purchase.
