How much should I loose?

When I started I looked at bmi, what I weighed in college and chose a number based in that yet I did not say a particular body fat percentage or something like that. I am not a small framed guy- I have a a pretty good amount of muscle as well. I am 40 years old 5 11 and was originally 250 lb and I chose to go down to 180 as my goal. I figured I was 165 when I went to college and slowly gained there sophomore year probably 180. I looked at bmi and 180 was just slightly higher then needed in the bmi scale. I figured that would be a good goal weight to start. Kind of scientific. I even said to myself I would see how I feel then and then possibly go as low as 165. I used to bodybuild/weightlift so my muscles have memory and come back. Certainly not as big as 20 years ago but still there. Recently in a conversation I realized that bmi is not the best measuremy because Arnold Shwartzenniger in his competition weight, as well as Labron James, and Michael Jordan in their competition weight would be listed as obese. So sould I be looking at waist not weight? Should I be looking at body fat percentage instead? Should I go to a personal trainer and get a impededence test for body fat. Was the original weight loss number good or too low? I do insanity workouts and calisthenics as my main exercise. So trying to maintain muscle mass. Lost 40 lb so far and 6 pant sizes. Wondering if I chose the appropriate goal weight or was it too low? Any opinions/experience in this subject of goal weight would be appreciated.
