What I have to do is implement a loop into this project and I was thinking about looping my DisplayInfo method to display all 4 houses as well as all the info about them at the same time.

public class Houses
{
    
    public string Address;
    public string Color;
    public int Price;
    public int RoomNumbers;

   
    public void DisplayInfo()
    {
            Console.WriteLine($"Address: {Address}");
            Console.WriteLine($"The color of the propery is: {Color}");
            Console.WriteLine($"The price of this property is valued at ${Price}");
            Console.WriteLine($"This property has {RoomNumbers} rooms.");
  
    }
}
class Program
{

    static void Main(string[] args)
    {
        
        Houses[] house = new Houses[4];
        {
            house[0].Address = "55 New Bridge Ln.";
            house[0].Color = "Red";
            house[0].Price = 200000;
            house[0].RoomNumbers = 2;


            house[1].Address = "101 Coders Dr.";
            house[1].Color = "Yellow";
            house[1].Price = 250000;
            house[1].RoomNumbers = 3;

            house[2].Address = "2041 Hungry Man Cir.";
            house[2].Color = "Green";
            house[2].Price = 350000;
            house[2].RoomNumbers = 5;

            house[3].Address = "3080 Falmoth Dr.";
            house[3].Color = "Purple";
            house[3].Price = 400000;
            house[3].RoomNumbers = 6;
        }
        for (int i = 0; i < house.Length; i++)
        {
            house[i].DisplayInfo();

        }
    }

} }

you are missing object initialization for single house, you can do it like this:

    var house = new Houses[]
    {
        new Houses{
          Address = "55 New Bridge Ln.",
          Color = "Red",
          Price = 200000,
          RoomNumbers = 2
        },
        new Houses{
          Address = "33 New Bridge Ln.",
          Color = "Orange",
          Price = 300000,
          RoomNumbers = 1
        }

        ///...
    };
    for (int i = 0; i < house.Length; i++)
    {
        house[i].DisplayInfo();
    }

in addition you can move to foreach loop

    foreach(var singleHouse in house)
    {
        singleHouse.DisplayInfo();
    }

in general I would use a constructor in your Houses class

public class Houses
{
    
    public Houses(string address, string color, int price, int roomNumbers)
    {
        Address = address;
        Color = color;
        Price = price;
        RoomNumbers = roomNumbers;
    }

...

    var house = new Houses[]
    {
        new Houses("55 New Bridge Ln.", "Red", 200000, 2),
        new Houses("33 New Bridge Ln.", "Orange", 300000, 1)
        ///...
    };
