Driveline angles, which axles you have, steering and brake up grades all come into play when you talk about running 35s. Any of those could cost more than the lift itself. Any time you go above 3" susp and maybe even a 3" susp lift you can run into drive line angle issues. Like stated above you can get around some suspension lift needs by dealing with fenders but you may still have issue with the axles, brakes that should be looked into.
