Rate Collateral

Rate collateral is the security a lender may require in exchange for holding a rate. It is not interest and not a fee in the ordinary sense; it is something of value the lender can look to if the borrower does not complete the mortgage on the agreed terms. Common forms include a cash deposit held by the lender, a collateral charge registered on title, or a pledged asset such as a term deposit. Rate collateral is not standard on every file — many lenders hold a rate on nothing more than an application and a credit check.

How rate collateral differs from a rate hold or rate lock

A rate hold or rate lock is the lender's promise to keep a quoted rate available for a set period. Rate collateral is the other side of that promise: what the lender asks for in return. Lenders tend to ask for it when a rate is held for an unusually long period, when the file sits near the edge of their policy, on construction and land financing, on private or alternative lending files, or on unusually large transactions where the lender wants evidence the borrower intends to close.

Forms rate collateral can take

• Cash deposit held by the lender, sometimes credited toward the down payment or closing costs at funding.
• Collateral charge — a collateral mortgage registers a charge on title that can secure the mortgage itself and, with some lenders, future credit as well.
• Pledged assets such as a term deposit or investment account assigned as security.
• A deposit or fee tied to the commitment, such as a commitment fee or holdback, which may or may not be refundable depending on the lender's terms.

Why it matters to a borrower

Collateral changes what a borrower gives up and what happens if plans change. A refundable deposit credited at closing is very different from a non-refundable one, and a collateral charge can remain on title after the mortgage is paid out, which can affect the cost of renewing, refinancing, or switching lenders later. Because terms vary by lender and by file, the practical step is to ask in writing what is being pledged, whether it is refundable, how and when it is returned, and what happens if the purchase or refinance does not complete. Comparing offers by total cost of borrowing rather than headline rate gives a clearer picture; see the guide to rate holds and rate locks for how holds interact with pricing.

Nothing here is a recommendation, and lenders set their own requirements. Confirm the specific terms in the commitment letter before relying on them.
