I am assuming you are looking at 4X4 Blazers as you are looking at a 69. Doglegs, rockers, torque boxes, toe boards where they meet the floors, the corners of the windshield frame under the triangular weatherstrip (hard to see if the top is on it), rearmost body mounts, and floor of the bed around the wheel wells and at the very back are common rust areas. Educate yourself on what should be correct. If it has been professionally restored, it should have the right motor and accessories under the hood i.e. correct intake, carb, air cleaner, radiator and shroud etc. etc. Inspect the wiring harnesses under the dash and under the hood - if they don't look neat and new (no birds nests) then an important step in the restoration was skipped. Make sure it has the right driveline and stock suspension in it - axle changes, lifts, different transfer cases etc. all detract from value. Check the VIN against the one on the title and against the frame and drive the vehicle. Take some cardboard to lay on and carefully inspect the underside - bring a flashlight. You are in Texas so one with a working original AC would be a plus. A good one fully restored that didn't start out as a rot box will generally go for at least $18000 at the very low end and to the mid 20's on up.
