A collateral mortgage is a type of readvanceable mortgage, meaning that you can borrow more money as you pay down your mortgage or if your home value rises. In order to do this, your lender will use your home equity as a collateral asset against your line of credit. As your home equity increases, your lender can extend more credit through a Home Equity Line of Credit (HELOC). This differs from conventional mortgages where you would need to refinance your mortgage in order to borrow more money from your lender.
Another difference is that a collateral mortgage is a loan that is not registered at your municipal registry office, which means it cannot be discharged or transferred to a different lender. If you were to refinance with another lender, you would have to pay legal fees to discharge and register your mortgage. In addition, your lender can require you to pay off any loans secured on your collateralized mortgage first. In contrast, a conventional mortgage charge can be directly transferred to other lenders.
You have a $600,000 house that you are buying using a collateral mortgage. You pay 25% down ($150,000) at the time of purchase. Your lender registers your home for 125% of the purchase price, meaning that if your home value rises, you will be able to access equity for up to 125% of the current value ($750,000).
The loan-to-value ratio allowed on your home is 80%, meaning that at any time you are able to borrow 80% of your appraised home value, minus the money you owe on it. At the time of purchase, since 80% of your home value is $480,000, and the money you owe on the home is $450,000, this means you are able to access $30,000 in home equity immediately.
Years later, you pay off $100,000 on your mortgage, and your home value rises to $700,000. Since you are able to borrow up to an LTV of 80%, you're eligible to access up to $560,000. With your mortgage of $350,000, this leaves you with $210,000 available for your HELOC.
Because your home was registered for $750,000 only, the maximum you would be able to borrow at any time would be $750,000, even if you pay off your original mortgage and your home price increases.
