A spousal buyout mortgage in Alberta lets one partner keep the home after separation by treating the buyout like a purchase instead of a refinance — and that distinction is everything. Under the insured spousal buyout program offered through Canada’s mortgage insurers (CMHC, Sagen and Canada Guaranty), the staying spouse can borrow up to 95% of the home’s value, rather than being capped at the 80% limit on a normal refinance. For many separating couples, that extra room is the difference between keeping the home and being forced to sell it.
Why does the 95% limit matter so much?
On a standard refinance, you can only borrow up to 80% of your home’s value. If most of your equity is locked in the house — which is common early in a mortgage — 80% may not cover both the existing mortgage balance and the departing partner’s share of the equity.
The buyout program exists for exactly that gap. Because the insurers treat the transaction as a purchase, the ceiling rises to 95% of value. The staying spouse takes a new mortgage that pays out the old one and pays the departing spouse their share, and title transfers into one name.
What do you need to qualify for a spousal buyout?
The common requirements are straightforward, though details vary by insurer — confirm how they apply on your file. Both spouses are currently on title to the home. There is a finalized separation agreement or court order that documents the buyout and each partner’s share.
A full appraisal establishes the home’s current value, since every number in the buyout flows from it. The staying spouse must qualify for the new mortgage alone, and the stress test applies just as it would on any new mortgage.
Joint debts named in the separation agreement may be included in the new mortgage under insurer rules — again, that is program-specific, so it needs to be checked against your agreement rather than assumed.

How does the buyout math actually work?
The framework is simple: appraised value minus the existing mortgage equals equity. The departing spouse’s share is whatever the separation agreement says — often half. The new mortgage is the old balance plus that buyout amount, and it must fit within the 95% ceiling. Also see what breaking the existing mortgage early would cost.
Here is an illustration with round numbers, not a quote: a home appraised at $500,000 with a $300,000 mortgage has $200,000 in equity. A 50/50 share is $100,000, so the new mortgage is $400,000 — 80% of value, which fits comfortably.
Now picture the same home with a larger mortgage or a larger agreed share. The $475,000 ceiling at 95% is what gives the buyout room a refinance cannot. Running these numbers early shows whether keeping the home works before anyone commits to it in writing.
That is why the mortgage math should be run before the separation agreement is finalized, not after. A buyout figure written into an agreement that no lender can fund helps nobody — the agreement and the mortgage have to be built together. A Mortgage Renewal Check is not the tool for this, but a proper review through my Pre-Approval & Refinance Check is where we test whether you qualify alone, and for how much. If the separation sale and purchase don’t align, see bridge financing when the separation sale and purchase don’t align.
