Depending on what you are looking for in a 3 bedroom rental the prices will vary substantially. Matthews will be the least expensive and you can get a decent place to live for around $1200 a month and up there. Southpark and ballantyne will be in the higher point also depending on waht you want in the place in addition ot the 3 bedrooms. But I have seen prices for rentals in there go from $1500 up to as much as $3000. Uptown area is probably be very expensive becuase of the location and proximity to uptown and expect to pay at least $2000 and up there
