Adding lots of JFrame components would be tidious so i wish if there is some way to create a way to add all the JFrame components at once.
lbl_info = new JLabel("Values with an astrick(*) are necessary");
		lbl_propertyNo = new JLabel("Property Numner: ");
		lbl_propertyName = new JLabel("* Property Name: ");
		lbl_purchasePrice = new JLabel("Purchase Price: ");
		lbl_rent = new JLabel("Rental charges (per month)");
		lbl_occRate =  new JLabel("Expected Occupancy Rate: ");
		lbl_mgmtFees = new JLabel("Property management fees (per month): ");
		lbl_insurance = new JLabel("Annual Cost of Insurance: ");
		lbl_maintenanceCost = new JLabel("Annual Maintenance Cost");
 
		txt_propertyName = new JTextField("* Property Name: ");
		txt_purchasePrice = new JTextField("Purchase Price: ");
		txt_rent = new JTextField("Rental charges (per month)");
		txt_occRate =  new JTextField("Expected Occupancy Rate: ");
		txt_mgmtFees = new JTextField("Property management fees (per month): ");
		txt_insurance = new JTextField("Annual Cost of Insurance: ");
		txt_maintenanceCost = new JTextField("Annual Maintenance Cost");
