Cross-collateralisation, explained
When one bank holds two of your properties as security for each other, the bank gains control and you lose it.
What it is
You own a home and want to buy an investment. The bank offers to lend the full price of the new property, secured by both. No cash deposit is needed and the paperwork is simple. Your two properties are now tied together.
What goes wrong
- Selling. When you sell one property, the bank decides how much of the proceeds it keeps to reduce the other loan.
- Revaluing. To release equity from one, the bank can revalue both. A fall in one drags down the total.
- Refinancing. You cannot move one loan to a better lender without unpicking the other.
- Trouble. If one loan runs into difficulty, both properties are exposed.
The standalone alternative
We release equity from your home as a separate loan split, secured only by your home, and use it as the deposit. The investment property then has its own loan, secured only by itself, and it can be with a different lender. The total borrowed is the same. Each property stands alone.
Already crossed?
It can usually be undone with new valuations and some restructuring, often during a refinance. If you own more than one property with the same bank, ask us to check how the securities are held.
Questions people ask
Is cross-collateralisation ever fine?
Sometimes it is the only way to make a purchase work, for example where equity is thin. We tell you when that is the case and plan how to separate the loans later.
