What is a Collateral Charge Mortgage?
A collateral charge mortgage is a type of mortgage registered on title that allows the lender to secure more than the actual loan amount, often up to a percentage of the property’s value. It enables borrowers to access additional funds, such as lines of credit or future refinancing, without re-registering a new mortgage.
Why Collateral Charge Mortgages Matter in Real Estate
Collateral charge mortgages matter in real estate because they offer flexibility for future borrowing, such as home equity loans. However, they may limit a borrower’s ability to switch lenders at renewal without incurring new legal costs. Borrowers should understand the implications before choosing this structure.
Example of a Collateral Charge Mortgage in Action
A homeowner obtains a $400,000 mortgage registered as a collateral charge for up to $500,000. Later, they can borrow an additional $50,000 under the same registration without redoing legal paperwork.
Key Takeaways
- Collateral charge mortgages secure more than the initial loan amount.
- Allow borrowers to access additional funds without new registration.
- Can include multiple credit products under one charge.
- May restrict switching lenders without legal costs.
- Important to understand registration terms before signing.
