Cross-Collateralisation Explained

Cross-collateralisation is when a lender takes more than one property as security for your loans. It often comes up when you use equity in your home to buy an investment property, and it can affect what happens when you sell, refinance or buy again.

The short answer

Cross-collateralisation means a lender holds two or more properties as security for your loans, so the properties are tied together. It can make buying with equity simpler to set up. The trade-off comes later: selling, refinancing or borrowing again against one property may need the lender to revalue and reassess both.

How it works

Say you own a home with equity and buy an investment property with the same lender. Instead of each property securing its own loan, the lender may take both properties as security for both loans. Together they make one pool of security.

Why it matters later

  • Selling: when you sell one property, the lender may decide how much of the sale proceeds go to reducing the loans, based on what it needs to hold against the other property.
  • Refinancing: moving one loan to another lender may mean moving both, or restructuring first.
  • Valuations: a fall in one property’s value can affect your whole position with the lender.
  • Buying again: using equity for the next purchase can depend on how the lender views every property together.

How standalone loans differ

With a standalone structure, each property secures its own loan. Some borrowers use a separate loan against their home for the deposit and costs, and a separate loan against the investment property for the rest, and some use more than one lender. Standalone structures can take more set-up, and each lender sets its own rules. Which structure suits you depends on your situation, and the tax treatment is a question for your accountant.

What to ask before you buy

Ask how each loan will be secured, what happens if you sell one property, and whether the loans can be split or moved later. We compare the structures available on our panel and explain them before you decide. General information only, not tax advice.

Questions

Common questions, straight answers.

Is cross-collateralisation bad?

Not in itself. It can be simple to set up, but it ties properties together, so the lender has a say over both when you sell or refinance one. Whether it suits you depends on your plans.

Can I undo cross-collateralisation?

Often, by refinancing or restructuring so each property secures its own loan. That may need new valuations and fees, and the lender assesses it like a new application.

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

Your loan documents list the security for each loan. Your lender or broker can confirm it.
