Blanket Mortgage

A blanket mortgage is a single mortgage secured by more than one property at the same time, letting one charge, one payment stream and one set of terms cover several separately titled properties.

How a blanket mortgage works

The lender registers one charge against each property in the group, and those properties become cross-collateralized: they all stand behind the same debt. The combined loan-to-value ratio is measured across the whole portfolio rather than property by property, so equity in one property can support borrowing on another. This differs from a collateral mortgage, which uses one property as security for a revolving or re-advanceable credit facility.

Blanket financing appears with credit unions, monoline lenders and private lenders, and it is used in real estate investment, farmland and multi-building portfolios.

Partial discharges and releases

Because several titles secure one debt, selling one property is not automatic. The borrower normally negotiates a partial discharge or release clause in the mortgage commitment, setting out how a property can be freed, usually by paying down a defined portion of the loan first. Without that clause the lender is not obliged to release a single title, so confirm the wording before signing.

Why it matters to a borrower

Possible advantages include one application, one set of legal fees, and pooled equity that may support a larger loan than separate mortgages would. The trade-offs are linked risk and less flexibility.

All properties are at risk if the borrower defaults; the lender can enforce against any or all of them.
Renewal, refinancing and rate decisions apply to the whole package.
Each title stays encumbered, which affects future sales and other borrowing.
Residential mortgage default insurance is generally tied to financing on a single property, so insured high-ratio borrowers typically do not use this structure; confirm the current CMHC rules.

Compare the two structures: separate mortgages give each property its own payment, term and exit, while one blanket mortgage offers flexibility in exchange for linked risk. Ask the lender how the combined loan-to-value is calculated and what triggers a demand for repayment.

Frequently asked questions

Is a blanket mortgage the same as a collateral mortgage?

No. A blanket mortgage secures one debt with several properties at once, and each property is registered as security for that debt. A collateral mortgage secures borrowing on one property and is drafted to allow re-advancing, which is why it is often paired with a home equity line of credit. Some lenders combine both features.

Can one property be sold while a blanket mortgage is in place?

Only if the lender agrees to a partial discharge or release. The commitment should state how much of the loan must be repaid before a title is freed. Without that clause the lender can decline the request. Review the wording with a real estate lawyer before you rely on selling part of the portfolio.

Why do lenders use blanket mortgages?

Pooling several properties into one charge lets a lender assess combined value and combined rental income rather than one property at a time. That can support larger loans and simplify administration, but it also means every property backs the entire debt, so a shortfall on one property affects the whole package.
