Ask to groom and tack yourself, go early morning and arrive early- that way they have little chance to work her before you get there, and if they've beasted her the night before, you'll notice dry sweat when you groom.
Take a trainer with you, or a farrier who knows what he's talking about, and let them tell you whether she can be 'helped' out of her little problems. Some are easier, some are harder.
Ride her as much as you can, as often as you can, before purchase. Her laziness may just be a sign of bad education, or ill fitting tack- you never know.
