Why Assuming a Mortgage Isn’t Always a Great Idea: Understanding the Risks

Back to all blog posts

In the world of real estate transactions, assuming a mortgage loan can seem like an attractive option, offering potential buyers a shortcut to homeownership. However, beneath the surface simplicity lie complexities and risks for the buyer and seller that may not make it the best choice for everyone. Let’s delve into why a mortgage assumption isn’t always a great idea.

Understanding Mortgage Assumption

Mortgage assumption occurs when a buyer takes over the seller’s existing home loan instead of securing a new one. This process maintains the original loan’s principal balance, interest rate, repayment period, and terms. Not all mortgage types allow assumptions, and it is not beneficial for many situations. Assumptions only apply to the remaining balance on a loan. If this is not enough to cover the price of the property, the buyer will have to come up with the difference. This can be done by either paying the remainder in cash, or taking a second mortgage loan out, such as a home equity loan. While it may seem straightforward at first, there are critical nuances to consider.

two types of mortgage assumptions: simple or novation

A simple assumption is a private transaction that occurs between a home seller and a buyer. The seller’s mortgage payments become the responsibility of the buyer as they take the title of the home. The transaction may not involve loan underwriting. If the buyer misses payments or defaults on the loan, the credit scores of both the buyer and the seller would be reflected because the seller is still liable for the outstanding mortgage debt.

In a novation, a mortgage lender transfers the rights and responsibilities of the existing mortgage from the seller to the buyer. This releases the seller from all liability on the loan and the buyer becomes solely liable for repayment. The buyer is required to formally qualify for the loan in order for the mortgage holder, or seller, to agree to a novation. Unless the mortgage is that of a relative’s, to assume a mortgage loan, the buyer will need to meet the same credit and income requirements that apply for a new loan.

The Drawbacks of Mortgage Assumption

1. Stringent Approval Process
Assuming a mortgage isn’t a walk in the park. Buyers must provide extensive documentation and undergo a lengthy approval process, often taking up to 90 days. This can be cumbersome and time-consuming, potentially delaying the home buying process.
2. Seller’s Liability
In a simple assumption, the seller remains liable for the outstanding mortgage debt. If the buyer defaults on payments, both parties’ credit scores are affected. This shared risk can strain the relationship between buyer and seller and lead to financial repercussions for both.
3. Limited Flexibility
When assuming a mortgage, buyers are bound by the existing terms of the loan. This includes fixed interest rates and repayment periods, leaving little room for negotiation or adjustment. As a result, buyers may find themselves locked into less-than-ideal terms, potentially leading to higher costs over time.
4. Risk of Disqualification
Unless assuming a relative’s mortgage, buyers must meet the lender’s same stringent credit and income requirements as they would for a new loan if the seller wants to completely release all liability on the loan, which they usually do. This increases the risk of disqualification, especially for buyers with less-than-perfect credit or irregular income streams. Even though buyers avoid loan origination costs with an assumption, they could be charged a loan assumption fee, various processing fees, and credit report fees on top of closing costs.
5. Covering equity
If the seller has significant equity in the property, the buyer could be at risk of paying a much higher down payment than they would for a new mortgage to cover the seller’s equity. They’ll need to inform the lender of the assumable mortgage that they’re getting a second mortgage because it could be prohibited by the first mortgage’s contract terms. The combined loans also cannot exceed the first mortgage lender’s required loan-to-value (LTV) ratio.

The Alternatives to Mortgage Assumption

While assuming a mortgage may offer certain benefits, including lower interest rates and reduced closing costs, there are alternative paths to homeownership that may prove more advantageous:
1. Securing a New Mortgage
Opting for a new mortgage provides buyers with the opportunity to shop around for the best rates and terms. It also allows for greater flexibility and customization, ensuring that the loan aligns with the buyer’s financial goals and circumstances.
2. Exploring Government-backed Loans
Government-backed loans, such as FHA, VA, and USDA loans, often offer assumable options with fewer restrictions. However, buyers should carefully weigh the benefits and drawbacks of each program before proceeding.
3. Considering Seller Financing
In some cases, sellers may be open to financing the purchase themselves, eliminating the need for a traditional mortgage altogether. This arrangement can offer greater flexibility and negotiation opportunities for both parties.
While assuming a mortgage may appear to offer a shortcut to homeownership, it’s essential to weigh the risks and benefits carefully. From stringent approval processes to limited flexibility and shared liabilities, there are significant drawbacks to consider. Exploring alternative financing options and consulting with a trusted real estate professional can help buyers navigate the complexities of the home buying process and make informed decisions that align with their long-term financial goals.
