Headers Location Null But Response Ok

Not sure whats going on here. Bit of a newb to API's and REST. I made an API that's working but the location is returning null? 

code:

using (var client = new HttpClient())
            {
                client.BaseAddress = new Uri(BaseEndPoint);
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                HttpResponseMessage response;

                Console.WriteLine("POST");
                User NewUser = new User();
                NewUser.Email = "TestUser999@email.com";
                NewUser.Handle = "TestUser999";
                NewUser.Password = "12345";
                NewUser.FirstName = "Test99";
                NewUser.LastName = "User99";
                NewUser.Address = "366 South Myrtle";
                NewUser.City = "Kankakee";
                NewUser.State = "IL";
                NewUser.Zip = 60901;
                NewUser.JoinDate = DateTime.Now;
                NewUser.Ban = false;
                NewUser.UserPoints = 100;

                response = await client.PostAsJsonAsync("api/user", NewUser);
                if (response.IsSuccessStatusCode)
                {
                    Uri userURL = response.Headers.Location;
                    Console.WriteLine(userURL);

                    Console.WriteLine("PUT");//currently Location Not Returning 
                    NewUser.UserPoints = 999;
                    response = await client.PutAsJsonAsync(userURL, NewUser);

                    Console.WriteLine("DELETE");//currently Location Not Returning 
                    response = await client.DeleteAsync(userURL);
                }
