Read this article first, like https
/www.lightandmatter.org/2017/equipment-reviews/camera-comparisons/nikon-d7500-vs-d7200-whats-the-difference/ That will help you make a tough decision
1) You Should Buy the Nikon D7500 If…
you plan to shoot a lot of action like: sports, news events, weddings, wildlife
you plan to shoot events in a dark setting: concerts, clubs, weddings, wildlife
you need to shoot 4K video, especially telephoto, or digitally stabilized HD Video
you want to use Nikon’s SB-5000 flashes and radio trigger system
you want a touch-screen and/or articulated rear LCD
2) You Should Buy the Nikon D7200 If…
you shoot landscapes or other detail oriented genres at low ISOs, including: studio portraits, product images, still-life works
you shoot action photography but don’t need a full 10 frames per second (the D7200 is a very capable action camera)
you shoot long events (or spend a long time in the field) and want better battery life
you want to save money on the body to buy better lenses (which is what I always recommend)
