Pretty simple but confusing why you ask this question over and over.

    public class Vehicles
    {
        public DateTime? MOTDate { get; set; }
        public DateTime? TaxDate { get; set; }
        public DateTime? RegDate { get; set; }
        public DateTime? InsuredDate { get; set; }
        [NotMapped]
        public string MOTDateString 
        { 
            get 
            { 
                return MOTDate?.ToString(); 
            } 
        }
        [NotMapped]
        public string TaxDateString { get; set; }
    }

Hi polachan,

Is there anything wrong?As mgebhard said,it could set the MOTDateString, TaxDateString automatically which depends on the value of  MOTDate , TaxDate.

Model:

public class Vehicles
{
    public DateTime? MOTDate { get; set; }
    public DateTime? TaxDate { get; set; }
    public DateTime? RegDate { get; set; }
    public DateTime? InsuredDate { get; set; }
    [NotMapped]
    public string MOTDateString
    {
        get
        {
            return MOTDate?.ToString();
        }
    }
    [NotMapped]
    public string TaxDateString
    {
        get
        {
            return TaxDate?.ToString();
        }
    }
}

Controller(For easy testing,I just set the value manually):

var data = new Vehicles()
{
    MOTDate = DateTime.Parse("2019-8-7"),
    TaxDate = DateTime.Parse("2020-7-7")
};

Result:

Best Regards,
