Cross-collateralisation is a lending arrangement where one lender holds more than one of your assets as security, or one asset for more than one loan, tying them together.

Also known as: cross-collateralization, cross-securitisation, cross security

Key points

  • Every asset in the arrangement supports every loan, so the loans stop being separate deals even though they have separate account numbers.
  • Lenders like it because the combined loan to value ratio looks safer than each loan judged on its own.
  • Selling one asset gets complicated: the lender can apply the proceeds to the whole debt rather than just the matching loan.
  • Untangling it later usually means a revaluation or refinancing one loan away to another lender.

Security (collateral)
security is the lender's interest in one asset, while cross-collateralisation links several assets and loans together
Personal guarantee
a guarantee adds a person's promise to repay, not another asset to the security pool

Frequently asked questions

How does cross-collateralisation work?

One lender takes security over more than one of your assets, or takes one asset as security for more than one loan. Each loan is backed by everything in the pool, so the lender can look to any asset if you fall behind, and it controls what happens when you sell one.

How do I know if my loans are cross-collateralised?

Check the security schedule in each loan contract. If a single loan lists more than one property or asset, or the same asset appears on several loans, they are linked. Your lender or broker can confirm it in writing, and a title search will show who holds what.

Is cross-collateralisation bad?

It is not automatically bad, but it costs you flexibility. It can help you borrow when one asset alone is not enough security. The trade off is that selling, refinancing or moving one loan elsewhere needs the lender's agreement, and the lender controls where sale proceeds go.

Can you undo cross-collateralisation?

Often yes. You ask the lender to release one asset and secure the loans separately, which usually needs a current valuation and enough equity in each. If the lender declines, the common fix is refinancing one loan to another financier. Both routes involve valuation and discharge fees.

Why do banks cross-collateralise loans?

It lowers their risk. Pooling the security means the overall loan to value ratio looks stronger than each loan alone, so they can lend more. It also keeps all of your borrowing with them, because moving one loan requires their consent to release the asset behind it.
