Bundled Mortgage (First-Second Bundle)

Definition

A bundled mortgage pairs a conventional first mortgage from a bank or B lender with a second mortgage from a separate lender — often a Mortgage Investment Corporation — funded together at closing to cover a shortfall the first lender's loan-to-value limit won't reach.

Why would a broker structure a deal as a bundled mortgage?

A bundled mortgage exists to close a financing gap: the client needs more borrowing power than a single A or B lender's maximum loan-to-value will allow, so a second lender funds an additional amount simultaneously, registered behind the first mortgage on title. It's a different structure from blend and extend, which combines old and new rates within a single lender's existing mortgage.

Because the second-position piece is usually unregulated private or MIC capital, a broker arranging a bundle has to watch the combined loan-to-value and combined monthly carrying cost carefully — not just the first mortgage's terms in isolation. Bundled structures are generally limited to conventional, uninsured deals, since default insurers do not permit simultaneous secondary financing behind an insured high-ratio mortgage.

How it’s used in Canada

Conventional deals only: bundling a first and second mortgage together is a conventional-financing technique; it is not available behind an insured high-ratio mortgage under CMHC, Sagen, or Canada Guaranty rules.

Second piece often unregulated: the second-position lender in a bundle is frequently a MIC or private lender, which is not subject to OSFI's Guideline B-20 the way the first lender may be.

Combined LTV and payments matter: brokers need to qualify and disclose the deal based on the combined loan-to-value and combined monthly cost of both mortgages, not just the first.

A workaround, not a workaround-free product: bundling has drawn regulatory attention when used to stretch beyond a lender's normal single-mortgage lending limits, so brokers should be transparent with clients about the total cost and risk of carrying two registered charges.
