The process is very simple and given step by step below;
Go to each room in your home and take pictures or videos of the items that you want to get covering your insurance plan.
Make a list of your items on paper or your computer.
Mention the estimated cost of each item in your list.
If you have receipts for important items, you should take pictures. Keep your receipts and a copy of them at different locations. Save the pictures on more than two devices for a good backup of your receipts.
Write down the model number and other specifications in your list if you have some expensive items at your home.
Calculate the estimated value of your clothes, other items at your home, or kitchen appliances.
Add all in the list to calculate the total amount of all items in your house or apartment.
Doing this will give you an estimated amount your insurance policy should cover. If you buy new items, add them to your list to have an updated list occasionally.
