The real savings come from comparing the entire transaction, not pretending an assumption has no closing costs.
By Sherri Echols, Broker Associate, eXp Realty
I’ve heard two opposite versions of assumable-mortgage costs.
Version One:
“Assumptions are basically free!”
Version Two:
“They’re so complicated they cost a fortune!”
Neither one helps.
An assumable mortgage can reduce or avoid certain costs associated with originating a completely new first mortgage.
That can be meaningful.
You still have closing costs.
You still have transaction expenses.
You may have assumption-related fees.
You may have title and settlement expenses, insurance, prepaid items, recording costs, inspections and costs connected with secondary financing if you need it.
So please don’t build your homebuying budget around the sentence:
“I heard assumptions are cheap.”
Let’s look at yours.
Why an Assumption May Cost Less Than a New First Mortgage
When you originate a brand-new mortgage, there can be costs attached to creating that loan.
Origination charges.
Underwriting expenses.
Discount points depending on the structure.
Other lender charges.
Potential valuation requirements.
An assumption uses the existing first mortgage instead of originating an entirely new first loan.
That means some new-loan costs may be reduced or avoided.
But that does not mean the transaction becomes free.
This is why I want buyers shopping for the financing as carefully as they shop for the property. I explain that approach in Shop for the House and the Money.
What Costs Don’t Magically Disappear?
You’re still buying real estate.
The title company did not become a charity because the seller’s mortgage rate is 3%.
Depending on the transaction, there may still be:
Title and settlement costs.
Recording charges.
Homeowners insurance.
Prepaid taxes or escrow items.
Inspections.
Assumption-processing charges.
Servicer fees.
And other transaction-specific expenses.
If there’s a second loan, that financing can carry its own closing costs too.
The exact number depends on the actual loan, property, servicer and structure.
That is why I want written estimates.
VA Assumptions Have Their Own Fee Rules
VA assumptions have their own program-specific costs.
Under current VA guidance, the VA funding fee for a loan assumption is generally 0.5% of the remaining loan balance, unless the assuming borrower qualifies for an applicable funding-fee exemption.
That is not 0.5% of the purchase price.
It is based on the loan amount being assumed.
And because exemption status and program requirements matter, I still want the actual file reviewed before anybody builds a closing budget around a general rule.
If the VA side of the transaction also raises entitlement questions, read VA Entitlement: The Part of a VA Assumption I Refuse to Treat Like a Footnote.
The Seller May Have Costs Too
Assumptions are not only about buyer savings.
The seller may have carrying costs if the transaction takes longer than another financing path.
There may be negotiation around closing costs.
The seller still has normal selling expenses.
If the mortgage is valuable, the seller may ask for stronger financial terms in exchange for participating in the assumption.
That doesn’t automatically make the deal unfair.
It makes it a negotiation.
What Is the Low Rate Actually Worth?
This is the fun part.
Suppose the buyer can assume a substantial mortgage balance at a rate several percentage points below realistic new financing.
There may be meaningful monthly savings.
There may also be substantial interest savings over the remaining term.
That financial benefit has value.
The seller may reasonably want some recognition for providing access to it.
Maybe through price.
Maybe fewer concessions.
Maybe reimbursement of some carrying costs.
Maybe stronger terms.
But the buyer still needs to keep enough of the benefit for the assumption to be worth doing.
If the seller captures every dollar of value through an inflated price, congratulations, we have successfully killed the golden goose.
That is why the best assumable mortgage is not automatically the one with the lowest rate. I explain that in The “Golden Goose” Isn’t the Lowest Mortgage Rate. It’s the Best House + Money Combination.
Premium Does Not Mean Greed
I’m comfortable saying a seller may receive a premium of sorts for valuable financing.
I’m also comfortable telling the seller they can’t lose their mind.
Those two positions fit together.
Imagine the financing could save the buyer meaningful money.
The seller should not necessarily give that away with no recognition.
But the home still has a market value.
Condition still matters.
Other homes still exist.
The buyer has alternatives.
We want a balanced exchange where both people get something useful.
Closing Costs Aren’t the Same as Cash to Close
This is another distinction worth making.
Buyer closing costs are one thing.
The seller’s equity gap is another.
Suppose you’re purchasing a $400,000 home and assuming $325,000.
That $75,000 difference is not a “closing fee.”
That is purchase price that still has to be delivered to the seller.
Then you add the buyer’s actual transaction costs.
When somebody asks:
“How much do I need to buy an assumable home?”
I don’t just ask about fees.
I ask:
How much equity are we solving?
That number can dwarf the actual closing costs.
Second Financing Can Change the Savings
Maybe you don’t have $75,000.
Could appropriate secondary financing cover part of the equity gap?
Possibly.
Now we have another interest rate.
Another payment.
Possibly another set of costs.
That does not automatically make the assumption bad.
But we need to combine everything.
Assumed first mortgage.
Secondary financing.
Taxes.
Insurance.
Mortgage insurance where applicable.
HOA dues where applicable.
Cash needed.
Then compare the complete structure with new financing.
I break down the second-mortgage question in Can I Use a Second Mortgage to Buy a Home With an Assumable Loan?
The Remaining Term Matters to Savings
Suppose you assume a mortgage with 22 years remaining.
Your long-term interest comparison should be based on that actual remaining term.
Not a fictional new 30-year mortgage at the seller’s rate.
The existing amortization matters.
That can be an advantage.
It may mean the debt is being paid off sooner.
It can also affect the monthly payment.
Again, we use real numbers.
The Process Itself Can Affect the Cost
Costs do not exist in isolation from the rest of the transaction.
If an assumption takes longer than another financing path, carrying costs and timing may matter to the seller.
If documents are incomplete or a file is poorly managed, delays may create additional pressure for both sides.
That is why the transaction has to be evaluated as a process, not just an interest rate.
I walk through the complete assumption process in How Does an Assumable Mortgage Actually Work From Start to Finish?
Sellers Should Market Savings Carefully
If I’m listing an assumable home, I want the financing advantage explained.
Not hyped.
I want a buyer to understand:
The approximate remaining balance.
The rate.
The remaining term.
The likely payment components.
The seller equity.
And how the assumed financing compares with a reasonable new-loan alternative.
What I do not want is:
“SAVE $250,000 GUARANTEED!!!”
Nobody knows how long that buyer will own the house.
Nobody knows whether they will refinance later.
Taxes and insurance can change.
The transaction still requires qualification and approval.
Facts sell better than hype anyway.
For sellers, the financing can still become part of the marketing strategy without turning into a ridiculous promise. That is the same principle behind Your Low Mortgage Rate Isn’t a Prison.
The Best Assumption Is a Balanced Transaction
Buyer gets meaningful financing value.
Seller gets paid for the house and equity.
Seller may receive stronger terms because the financing is attractive.
Buyer doesn’t surrender the entire benefit.
Costs are understood.
The equity gap is solved.
The property itself makes sense.
That’s a good transaction.
An assumption being “cheap” is not the goal.
A financially smart purchase and sale is the goal.

Frequently Asked Questions
Do assumable mortgages have closing costs?
Yes. An assumption may reduce or avoid some costs associated with originating a completely new first mortgage, but normal real-estate expenses, assumption-related charges and other transaction-specific costs can still apply.
What is the VA assumption funding fee?
Under current VA guidance, the funding fee for a VA loan assumption is generally 0.5% of the remaining loan balance unless the assuming borrower qualifies for an applicable exemption.
Is the equity gap a closing cost?
No. The equity gap is generally the difference between the negotiated purchase price and the remaining balance of the mortgage being assumed. That amount is separate from the buyer’s transaction and closing expenses.
Can a seller charge more for an assumable mortgage?
Valuable financing may support stronger terms or a reasonable premium, but the property still needs to make sense at the negotiated price and the buyer still needs to retain enough benefit for the assumption to be worthwhile.
Can a second mortgage reduce the cash I need?
Potentially. Secondary financing must be available, compatible with the assumption, acceptable under the applicable requirements and financially sensible for the buyer.
Should I compare an assumption with new financing?
Always. Compare the full structure, including the remaining first-mortgage balance, rate, term, equity gap, cash needed, any secondary financing, transaction costs and complete monthly payment.
