Set a property value to 0, when creating a user! MVC : how can i set the balance property to 0, when registering a new account on my create view in mvc. I want the balance to be 0 as default for the user who has just been registered!

        namespace CSGO_MVC.Models
    {
        public class SteamAccount
        {
            [Key]
            public int Id { get; set; }
            public long SteamId { get; set; }
            public Balance accountbalance { get; set; }
            public string UserName { get; set; }
            public string Password { get; set; }
            public bool UserStatus { get; set; }
            public string TradeLink { get; set; }
    
        }
        
         
    }


Here is my controller 


    [HttpGet]
    public ActionResult Create()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Create(SteamAccount acc)
    {
       
        if (ModelState.IsValid)
        {
           

            AccountRepo.Insert(acc);
            AccountRepo.Save();
            return RedirectToAction("Index");
        }
        else
        {
            return View(acc);
        }
    }

Thank you guys!
