Financing a rural build with a line of credit the new lender had to accept

The situation

Huong and Anh had already tried to handle the purchase themselves before they came to us. Huong worked as a software developer and Anh as a chiropractor, both with strong, stable incomes, and they had found a rural lot near Newmarket where they wanted to build. Rather than involve a lawyer from the start, they had negotiated the purchase price directly with the seller, Kittipong, who was selling the land himself without an agent or a lawyer of his own, and had used a generic purchase agreement template they found online to put the deal in writing.

The arrangement had gone sideways within weeks. Kittipong, working from the same template, had made his own changes to a clause about the deposit and another about the closing date, initialing them without telling Huong and Anh, and the copy each side believed they had signed no longer matched. Neither party had done anything dishonest; both were simply negotiating a significant transaction, worth close to a million dollars once the lot and planned build were counted together, without anyone trained to keep the paper trail consistent.

Underneath that problem sat a second one. Huong and Anh planned to fund part of the down payment, roughly $180,000, by drawing on the home equity line of credit attached to the readvanceable mortgage on the home they already owned. That kind of line grows in available credit as the mortgage balance is paid down, and using it to fund a new purchase is common enough. But a construction lender financing a new build on a rural lot underwrites the file differently than a lender financing a resale home, and the source of every dollar in the down payment needs to be disclosed and documented in a form the lender will accept.

By the time Huong and Anh called our office, they had a purchase agreement with unclear terms, a seller who did not fully understand what he had agreed to, and a financing plan that had not yet been presented to their lender in the form the underwriting would require. They still wanted to close on the lot and start the build on schedule; what they had tried on their own had gotten them partway there and then stalled.

The legal question

The first question was whether the agreement the two sides believed they had actually existed as a single, enforceable document. When each party has initialed different, uncoordinated changes to a shared template, there is a real risk that no meeting of the minds occurred on the terms that were changed, which can leave either side able to argue the agreement is void, or open to dispute over which version governs. Because Kittipong was self-represented, he had also made changes without appreciating what they meant, which meant simply enforcing the document as written was not a safe answer either; it needed to be clarified and re-executed properly, with both sides working from an identical copy.

The second question concerned the down payment. A readvanceable mortgage with an attached line of credit lets a homeowner borrow against equity as it builds, and using that credit for a down payment on another property is legitimate and common. But lenders scrutinize the source of down payment funds closely, particularly on construction financing, because a down payment funded by new debt changes the buyer's real debt-service position in a way that funds from savings do not. If the source is not disclosed accurately, the lender's underwriting is based on an incomplete picture, and the mortgage commitment itself can be at risk of being treated as obtained on a misrepresentation, a serious problem to discover after a construction draw schedule is already underway.

Kittipong being self-represented changed the dynamic of the negotiation in ways that needed careful handling. He was not hostile, but he did not have anyone advising him on what was standard versus unusual, which meant requests that would ordinarily be handled through a quick exchange between two lawyers instead required plain, careful explanation directly to him, in writing, so that what he agreed to was something he actually understood. Rushing that process, or treating him as though he had the same grasp of the transaction that a represented seller would, would have created new risk rather than resolving the existing one.

What we did

1. Reviewed both marked-up copies of the template agreement line by line against each other, identifying every clause where the two versions diverged, so the actual points of disagreement were isolated rather than assumed. This mattered because Huong and Anh had been negotiating for weeks on the belief that they and Kittipong were working from an identical document, and a careful side-by-side comparison resolved in a single afternoon what could otherwise have taken further rounds of confused correspondence to untangle, or worse, gone unnoticed until closing.
2. Drafted a single consolidated agreement that resolved each divergence explicitly, with plain language explaining the deposit and closing-date terms so Kittipong could review it without a lawyer of his own and still understand exactly what he was agreeing to. Writing for a self-represented reader rather than relying on legal shorthand meant fewer follow-up questions later and produced a document both sides could genuinely rely on as the single, governing version of their deal.
3. Walked Kittipong through the consolidated draft directly, in writing and by phone, flagging that he was welcome to seek independent legal advice before signing. This was the right approach because a self-represented seller who later felt rushed or confused could have challenged the whole agreement, so taking the time to keep the process transparent produced a clean, informed signature and closed off that risk before it could ever surface.
4. Obtained a formal letter from Huong and Anh's home equity lender confirming the available credit limit on the line and the specific amount they intended to draw. A construction lender cannot simply take a borrower's word for where down payment money is coming from, so this third-party confirmation gave the underwriting file a verifiable document rather than a client statement, which is exactly the kind of proof that avoids delays once the file reaches approval.
5. Prepared a source-of-funds disclosure for the construction lender that set out the line of credit draw plainly, including how the draw affected the couple's overall debt position and monthly carrying costs. Doing this proactively, rather than waiting for the lender to ask, meant the underwriting reflected the real financing structure from the outset and produced an approval that could not later be reopened on the basis that something material had been left out.
6. Coordinated timing between the equity draw and the deposit so the funds moved through the transaction in a sequence the lender's underwriters could trace cleanly from account to account. This was important because even an innocent gap in the paper trail can look like layering to an underwriter reviewing the file cold, and a clean, traceable sequence produced a funds history that matched the disclosure exactly, with nothing left for anyone to question.
7. Confirmed the construction lender's acceptance in writing before advising Huong and Anh to proceed with further deposits. Committing more of their money to the deal before the financing structure had formal sign-off would have put them at risk if the lender pushed back, so holding that line protected their funds and produced a firm, documented green light before any further money moved.
8. Set out a written record of the whole file for the couple's own reference, summarizing the consolidated agreement's key terms and the lender's disclosure requirements. Because the build financing would move through further draw stages after closing, this record gave Huong and Anh a single clear reference document to work from, rather than needing to reconstruct the reasoning behind each term from memory months into construction.

The outcome

The purchase closed on the terms set out in the consolidated agreement, with Kittipong signing without objection once he understood what each clause actually meant. The confusion from the earlier, uncoordinated template did not resurface, because there was no longer any ambiguity about which version of the deal governed, and both sides worked from a single document through to closing.

The construction lender accepted the down payment as disclosed, treating the home equity draw as a legitimate, documented source of funds rather than a gap to investigate further or a reason to slow the file down. Huong and Anh's overall borrowing costs were somewhat higher than if the down payment had come purely from savings, since they were now carrying the equity line balance alongside the new construction mortgage, but that cost had been part of their plan from the outset and was never hidden from the lender at any stage of underwriting.

Because Kittipong was self-represented, the file required more direct communication and more patience than a transaction between two represented parties usually does. That extra care is also what avoided a dispute. A confused seller who later felt he had been rushed into signing something he did not understand would have been a far more serious problem, potentially unravelling the deal entirely, than the additional hours it took to walk him through the agreement properly and let him ask questions before he signed.

Huong and Anh's build proceeded on schedule, with a financing structure their lender had reviewed and accepted rather than one assembled after the fact under pressure. They still make the equity line payments alongside their new construction mortgage, a cost they had planned for and understood clearly before closing rather than discovering it as a surprise once the build was already underway.
