Two sisters, one numbered company, and a lender that wanted more

Mihaela and Mona had used a numbered company to hold a small rental property for years. Buying a bigger family home the same way did not protect them the way they expected it to.

The situation

Mihaela and Mona are sisters, not a couple, and that distinction shaped almost every decision in this file, from how ownership was split to how the sisters thought about what happened if one of them, someday, could not pay her share. Roughly eight years earlier, on their accountant's advice, they had pooled savings and bought a small rental duplex together through a numbered company, splitting ownership evenly and using the corporate structure mainly to keep the property's liabilities separate from their personal finances and to simplify their eventual estate planning between them. The arrangement had worked without incident for years, generating modest rental income and, more recently, real equity as the property's value grew.

Mihaela worked as an early childhood educator and Mona as a dental assistant, both steady but modest incomes, and neither had significant savings outside what the rental property had generated over the years. Neither sister was married, and both had built their financial lives around a shared, cautious plan rather than around a single household income the way many couples do. When their aging parents needed a larger, more accessible home to live in with them, the sisters decided to sell the duplex and use the proceeds, combined with careful additional saving, toward a bigger shared property in Kanata in the roughly $400,000 to $600,000 range that could house both their households, and their parents, under one roof.

Because the numbered company already existed and already held the rental property's proceeds after that sale closed, continuing to purchase through the same corporate entity seemed like the straightforward path. It avoided winding up the company and distributing funds personally, which would have triggered its own tax consequences, and it kept the arrangement consistent with how the sisters had structured their finances together for years. Their accountant, consulted again for this purchase, saw no reason to change course.

What neither sister anticipated was how a lender would view a small, closely held numbered company with no independent credit history applying for a residential mortgage. Rania, the underwriter handling the file at their bank, was clear from the first conversation: the company itself had no track record the lender could rely on, and approval would depend on personal guarantees from both sisters regardless of the corporate structure. For Mihaela and Mona, that requirement cut directly against the reason they had used a numbered company in the first place, and it arrived just as their parents' timeline for moving was becoming urgent.

What the other side was relying on

Rania's position was not unusual, and it was not really open to negotiation in principle. Lenders routinely require personal guarantees when a mortgage applicant is a closely held corporation with no meaningful independent credit history or income of its own, because the company's ability to repay a mortgage over twenty or twenty-five years depends entirely on the individuals behind it, not on the corporate shell. A numbered company with two shareholders and no other assets or operating history offers a lender essentially nothing to rely on except the shareholders themselves.

The lender's standard policy, which Rania cited directly, treated corporate residential borrowers as functionally equivalent to personal borrowers for underwriting purposes, just with an extra layer of paperwork. That policy did not distinguish between a numbered company set up for genuine business reasons, as the sisters' had been for the rental duplex, and one set up purely to try to obtain a mortgage without personal exposure. From the lender's perspective, the guarantee requirement was simply how the risk got covered either way.

This mattered because the sisters' entire reason for using the corporate structure had been liability protection, keeping the property's debts and risks separate from their personal finances. A personal guarantee undoes a meaningful part of that protection: if the company defaulted on the mortgage, the lender could pursue Mihaela and Mona personally for the shortfall, the exact exposure the corporate structure was meant to prevent. Rania's team was, in effect, relying on a common and largely accurate industry assumption that closely held numbered companies rarely have enough independent substance to be treated any differently.

With a limited budget for legal fees, Mihaela and Mona could not afford an extended negotiation or a fight over lending policy in principle. Every hour of legal time had to be aimed at something that would actually change their exposure, not at arguing a point the lender was never going to concede. That reality was as much a part of the file as the guarantee itself: a client with a larger budget might have shopped the mortgage to several lenders to see whether any would treat the corporate structure differently, but that was not a realistic option here, and it was important to be honest about that early rather than let the sisters spend money testing a door that was very unlikely to open.

What we did

  1. Reviewed the numbered company's structure and history to confirm there was no realistic alternative lender likely to waive the guarantee requirement, so the sisters were not spending money chasing an option unlikely to exist rather than working the one actually in front of them, given how little room their budget left for a search that was unlikely to change the answer.
  2. Explained clearly what a personal guarantee actually exposes, in plain terms, so Mihaela and Mona understood the real difference between the corporate liability shield they thought they had and the personal exposure the guarantee would create, before either of them signed anything at all, and before the pressure of a closing date could rush that understanding past two people who deserved to weigh it properly first.
  3. Reviewed the guarantee document line by line against the lender's standard template, checking specifically whether it was limited to the mortgage debt itself or drafted broadly enough to cover other present or future obligations to the same lender, a distinction the standard form did not make obvious on a first read and one the sisters would never have caught reviewing the document on their own.
  4. Negotiated to narrow the guarantee's scope to the specific mortgage on the Kanata property, removing broader language in the lender's draft that would have exposed the sisters personally for other unrelated obligations of the company, a change that cost little in negotiation time but meaningfully limited what either sister could ever be pursued for if their finances outside this one property ran into difficulty later.
  5. Confirmed the guarantee was several, not joint and several without limit, meaning each sister's personal exposure was tied to her actual share of the debt rather than each being on the hook for the full amount if the other could not pay, an important distinction given they were sisters with separate households and finances, not a couple sharing one income.
  6. Advised on the tax and structural consequences of keeping the property in the numbered company versus transferring to personal ownership, confirming that continuing with the corporate purchase, despite the guarantee requirement, still avoided the immediate tax cost of winding up the company that would have come with switching structures at this stage of a tight-budget purchase, money the sisters simply did not have room to spend on a restructuring they did not actually need.
  7. Kept the scope of work tightly focused on the guarantee terms and closing mechanics, deliberately avoiding broader corporate reorganization advice the sisters could not afford and did not need to complete this specific purchase, even though a wealthier client facing the same guarantee demand might reasonably have asked us to look at the whole corporate structure more broadly rather than just this one purchase.
  8. Set out the sisters' respective positions in writing between themselves, confirming in a short internal memo how their several guarantee shares corresponded to their ownership split in the company, so there was no ambiguity later about who owed what if the mortgage ever became a problem, protecting the sisters' relationship with each other as much as either one's individual finances.
  9. Confirmed the land transfer tax and closing cost implications of proceeding through the numbered company rather than personally, checking that continuing the existing structure did not trigger any additional charges beyond what a personal purchase in Kanata would have involved, which it did not, closing off one more expense the sisters had been quietly worried about without needing to spend legal time confirming it further.

The outcome

The purchase closed with personal guarantees in place for both sisters, tied specifically to the mortgage on the Kanata property and structured on a several rather than unlimited joint basis. That is the honest bottom line: the liability protection Mihaela and Mona had originally sought through the numbered company was not fully preserved. If the mortgage were ever to go into default, both sisters remain personally exposed for their respective shares, something a personal purchase would have meant regardless, but something the corporate structure had been specifically meant to avoid.

The narrower scope of the guarantee, limited to this mortgage rather than any future dealings with the lender, and the several rather than joint-and-several structure, meant the exposure that remained was contained to what was actually necessary rather than the broadest version the lender's standard documents would otherwise have created. That distinction mattered practically: it meant Mona's exposure was not tied to Mihaela's share and vice versa, which the sisters considered important given they were managing separate households sharing one property.

Legal costs stayed within what the sisters had budgeted, because the work stayed focused on the guarantee terms and closing rather than expanding into a broader corporate restructuring the family could not afford at this point. The company retained the property, the tax consequences of an unwind were avoided for now, and the sisters closed on their parents' new home on schedule. It was not the outcome they had hoped for when they first assumed the corporate structure would insulate them the way it had for the rental property, and we were clear with them throughout that it would not. What we could do, and did, was make sure that gap was as narrow and as well understood as possible before either sister signed, rather than something they discovered only if the mortgage ever went into difficulty.

Mihaela and Mona's parents moved into the Kanata home on the schedule the family had planned around, which was, in the end, the outcome that mattered most to them day to day. The guarantee sits in the background of that arrangement now, a real but bounded risk the sisters understand clearly, rather than an unclear one they might otherwise have signed without fully grasping what it meant.

What you can learn from this

  • A numbered company with no independent credit history rarely protects you from personal guarantee requirements when applying for a residential mortgage, no matter how genuine the original business reasons for setting it up were.
  • If a personal guarantee turns out to be unavoidable, its scope matters as much as its existence; always ask whether it is limited to the specific loan or drafted broadly enough to cover other present or future obligations.
  • When multiple people are guaranteeing a debt together, ask specifically whether the obligation is several or joint and several; the difference changes significantly what happens to each person if one of them cannot pay their share.
  • Keeping an existing corporate structure can still make good tax sense even in a purchase where it does not deliver the liability protection you originally expected it to provide.
  • On a tight legal budget, focus negotiation effort on the specific document terms that actually change your exposure, rather than on arguing broader points a lender's standard policy is very unlikely to concede.
