Depending on the size of the loan, many things can be mortgaged. Usually people are talking about mortgage in the case of pretty big loans, like home loans. When you are buying a new home, usually you do not have the possibility to pay the whole house with a sum. You have to take a loan to be able to pay the whole. If you take one of the home loans, the mortgage will be the house itself. This can have advantages and disadvantages, too. The advantage of putting the new home as mortgage is that you can move in right after solving the paper work. On the other hand, if you will not be able to pay the debt, you can lose your home.
To change the mortgage from the home to something else does not require much. If you have a lot of valuable things in your house, you can count them together and put your home equity as mortgage. Home equity contains all the valuable things in your possession. The creditor will send professionals to estimate the value of your home equity, and you will be able to take a loan that can be covered by this value. This is a good solution to secure a loan. Think about it. You cannot know what the future brings, so if you get in trouble and you cannot pay the debt, you will lose the things in the house, but not the house itself.
Other things can be mortgaged, too. For example in the case of car loans the mortgage is the car. In this case it is exactly like with home loans. You will be the real owner of the car only after paying the whole loan.
The truth is that no matter for what you take the loans, the point is that you have to secure them with something. Otherwise you will have to pay a lot on the long run. Considering this, anything can be mortgaged. Even your garage can act as a mortgage, if it’s valuable enough to cover the loan that you take.
You can also mortgage your overseas property for example. For example Spanish mortgages are available if you own a vacation property in Spain.
