How to Legally Assign a Construction Mortgage

Why More Mortgage Options Matter—Especially for Assignment Purchases

One of the biggest advantages of working with an independent mortgage professional is access to choice.


Instead of being limited to one lender and one set of products, mortgage brokers work with multiple lenders—each with different guidelines, risk tolerances, and mortgage solutions. That flexibility becomes especially valuable when your situation doesn’t fit neatly into a “standard” box.


A great example of this is purchasing new construction through an assignment contract.


Why Assignment Purchases Can Be Challenging

Assignment purchases are often viewed as higher risk by traditional lenders. Rather than declining these deals outright, many lenders quietly make them difficult by adding layers of conditions, restrictions, or uncertainty.

This can lead to delays, frustration, or financing falling apart late in the process.


The Good News

There are lenders—available exclusively through the broker channel—that have clear, favourable policies for assignment purchases. With the right lender and proper planning, these transactions are absolutely doable.


Typical Financing Requirements for Assignment Purchases

While every situation is unique, many lenders that allow assignment financing look for the following:

  • Standard purchase qualification, including income verification, credit, and down payment
  • Assignments accepted at either the original purchase price or current market value
  • Minimum 620 credit score, with no prior bankruptcies or consumer proposals
  • The full down payment must come from the purchaser—seller incentives cannot be used


Required Documentation

To secure financing, lenders typically require:

  • The original purchase agreement signed by all parties
  • The MLS listing (if applicable)
  • The assignment agreement signed by the builder, original purchaser, and new buyer
  • Any side agreements outlining changes to the purchase price
  • A full appraisal to confirm value


This list isn’t exhaustive, but it highlights that while assignment purchases require more coordination, they are very achievable with the right lender and guidance.


Final Thoughts

Assignment contracts can open doors to great opportunities—but only if your financing supports the transaction. This is where access to multiple lenders and specialized policies makes a real difference.

You’ve outgrown your current home. It no longer fits your life, so moving makes sense. And you’re not interested in juggling two properties. Selling first and buying something new feels like the right move. Ideally, you want possession of the new home before leaving the old one. That overlap makes moving easier, reduces stress, and gives you time to paint, renovate, or settle in before the boxes arrive. But there’s a common challenge. What if the down payment for your next home is tied up in the equity of the one you’re selling? That’s where bridge financing comes in. How bridge financing works Bridge financing temporarily unlocks equity from your current home once it has a firm sale . It bridges the gap between selling your existing property and purchasing your next one, allowing you to use that equity toward your down payment. What about competitive markets? In a hot market, a strong offer often means a larger deposit . If you don’t have that cash sitting in your account, but you do have equity, a deposit loan can help you compete with confidence. The non-negotiable requirement To qualify for bridge financing or a deposit loan, your current home must have a firm, unconditional sale . No firm sale = no bridge or deposit loan. Lenders need certainty to calculate available equity and manage risk. Bottom line A firm sale is the key that unlocks bridge financing and deposit loans. If you’re planning a move and want to understand how these options could work for you, let’s talk. I’m always happy to walk you through your options and help you plan your next step with confidence.
